<p>This section of the PowerVR SDK Browser provides a range of example applications and tutorials that are implemented across multiple APIs. These examples include optimized and thoroughly commented code. They also make consistent use of our Framework and provide a wealth of techniques for the novice user to the advanced developer.</p>
<p>To get started with the examples:</p>
<ul>
<li>Select a navigation sub-tab to view the examples for a specific API. The tabs are organised by API name.</li>
<li>The examples are classified into beginner, intermediate and advanced categories. Browse to the desired example to view its details and corresponding .cpp and project files.</li>
<li>Additionally, use the <a href="../../Examples" target="_blank">Examples</a> folder supplied with this SDK to explore them.</li>
</ul>
<p><em><strong>Note:</strong> Some of the examples do not handle screen rotation, in order to keep the code as simple as possible. On devices with a portrait display the example images may appear stretched.</em></p>

<!--API_DESCRIPTION-->
<h1>OpenGL ES Examples</h1>
<h3>Programmable pipeline: OpenGL ES 2.0, 3.0 and 3.1</h3>
OpenGL ES is a cross-platform API for 2D and 3D graphics on embedded systems such as mobile phones, tablets, vehicles and appliances. It is a subset of desktop OpenGL, tuned to expose the most efficient features of embedded GPUs.
<p><br><b>OpenGL ES 2.0</b> introduced a programmable pipeline into the API, deprecating a lot of the fixed functionality in OpenGL ES 1.x in favour of programmable shaders. This is the most popular 3D API in existence today, and is widely used in most 3D and many 2D games on mobile and embedded devices. Shaders provide a lot of advanced functionality and flexibility to renderers resulting in substantially more ways to improve graphics fidelity and performance than in OpenGL ES 1.x. Supported on PowerVR Series5 and later</p>
<p><br><b>OpenGL ES 3.x</b> adds to the already powerful OpenGL ES 2.0 things such as multiple render targets, standardised texture compression, a new shading language and far more control over texturing. OpenGL ES 3.1 also adds compute shaders and advanced compute functionality, allowing General Purpose on GPU (GPGPU) processing. Supported on PowerVR Series6 and later</p>
<p>The descriptions below specify the minimum API version the demo has been written for. When more than one version are listed, there is differentiated code for each of them. For example, OpenGL ES 2.0/3.0 will have two different versions, one of them will make use of OpenGL ES 3.0 specific features.</p>

<p><strong>Description:</strong></p>
<p>Bump mapping is a technique for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during the illumination calculations. The result is an apparently bumpy surface rather than a perfectly smooth surface although the surface of the underlying object is not actually changed. This technique is used extensively in graphics applications to add perceived detail to models without adding further geometry.
This example can be used as the baseline for rendering an object. Uses different shaders for OpenGL ES 2.x and OpenGL ES 3.x

<div class="FullDescription" id="TexturingFull">
<p><strong>Description:</strong></p>
<p>Traditional rendering algorithms submit geometry and immediately apply shading effects to the rasterized primitives. Complex shading effects may require multiple render passes to produce the final pixel color, with the geometry submitted every pass. Deferred shading is an alternative rendering technique that submits the scene geometry once, storing per-pixel attributes into local video memory to be used in the subsequent rendering passes.
In these later passes, light volume primitives are rendered, and the per-pixel attributes contained in the buffer are retrieved at a 1:1 mapping ratio so that each pixel is shaded individually.
In the PowerVR architecture, the user can use fast on-chip memory instead of Multiple Render Targets, by utilising the Pixel Local Storage extension.
If running from a command line, add -forcemrt to force Multiple Render Targets rendering.
Requires at least OpenGL ES 3.0 capability for either MRT or PLS. Requires the extension GL_EXT_shader_pixel_local_storage for PLS.

<p>The Skinning demo shows a Skinned Character in combination with bump mapping. Skinning is the act of animating a vertex over time given a set (palette) of matrices and a known set of blend weights assigned to those matrices. For each frame the Matrix Palette is recomputed based on time. PVRAssets and POD files support skinning. either full transformation Matrices, or Quaternion rotation with Scaling and Translation vectors. The provided POD file contains matrix animation.
This example is using BoneBatching, which separates the mesh in smaller matrix palettes (Bone Batches) so that they can fit in the maximum number of allowed Uniform variables.
Up to 4 matrices from the palette, along with 4 weights can used for each vertext by the vertex shader to update the position to obtain the current animation frame position.

<h1>Framework</h1>
<p>The PowerVR Graphics SDK provides a framework which is made up of PVRShell and PVRTools.
PVRShell is a simple, light-weight architecture for the barebones of application setup, shutdown and event handling.
It is designed to streamline the process of writing cross-platform graphics applications.
PVRTools, on the other hand, is a cross-platform tools library containing the most commonly used functionality in a 3D graphics application.</p>

<div id="Overview">
<h2>Overview</h2>
<p>The PowerVR Framework is a complete framework source code, re-written from scratch and targeted for all major platforms, such as Windows, Linux, and OS X, as well as Android and iOS mobile platforms. The key strength of the PowerVR Framework is that it is platform-agnostic, meaning that with the same code, it is possible to compile for different platforms without changing source code.</p>
<p>The majority of the code is written in C++ and tested across different compilers (namely Visual Studio 2010, GNU Compiler Collection and Clang) using modern styling and in general provides a complete framework for application development. There is also the supporting per-platform code (Objective-C code for iOS and OS X, some Java code for Android, etc.), and project files.</p>
<p>The Framework consists of separate libraries that are divided by functionality, as shown in the figure below. These modules are provided to be compiled as static libraries, but you can choose to use them differently, if needed.</p>
<img src="./images/PowerVRFrameworkComponents.png"/ style="display:block; margin-left:auto; margin-right:auto">
<h3>PVRCore</h3>
<h4><strong><a href="../../Framework/PVRCore/Documentation/Index.html" target="_blank">View source code documentation</a></strong></h4>
<p>This is the supporting code of the library to leverage for your own use. PVRCore is also used by the rest of the Framework and because of that, all examples using any other part of the Framework should link with PVRCore.</p>
<h3>PVRAssets</h3>
<h4><strong><a href="../../Framework/PVRAssets/Documentation/Index.html" target="_blank">View source code documentation</a></strong></h4>
<p>This is the Framework’s asset code. It includes classes and helpers for scene representation, asset loading code, etc. PVRAssets supports the loading of POD files, PVR and PFX materials format, as well as limited support for a number of texture formats.</p>
<h3>PVRShell</h3>
<h4><strong><a href="../../Framework/PVRShell/Documentation/Index.html" target="_blank">View source code documentation</a></strong></h4>
<p>This is the native system abstraction (event loops, surfaces, windows, etc.) which greatly simplifies cross-platform compatibility. Essentially, PVRShell provides you with useful scaffolding for cross-platform development.</p>
<h3>PVRApi</h3>
<h4><strong><a href="../../Framework/PVRApi/Documentation/Index.html" target="_blank">View source code documentation</a></strong></h4>
<p>This is the actual Graphics API abstraction. PVRApi is a very powerful framework that allows cross-API development. In combination with PVRShell, this provides remarkable support to write code intended to run across different platforms, utilizing different APIs.</p>
<h3>PVRPlatformGlue</h3>
<h4><strong><a href="../../Framework/PVRPlatformGlue/Documentation/Index.html" target="_blank">View source code documentation</a></strong></h4>
<p>This helper project provides necessary abstraction between the underlying system (PVRShell) and graphics API (PVRApi).</p>
<h3>PVRUIRenderer</h3>
<h4><strong><a href="../../Framework/PVRUIRenderer/Documentation/Index.html" target="_blank">View source code documentation</a></strong></h4>
<p>This text and image 3D printing code can also be used as a text or sprite renderer code. It is built on top of PVRApi, making it inherently API-agnostic and contains code for using different parts of fonts to display text.</p>
<h3>PVRCamera</h3>
<h4><strong><a href="../../Framework/PVRCamera/Documentation/Index.html" target="_blank">View source code documentation</a></strong></h4>
<p>This is the code for interfacing with the camera of mobile platforms.</p>
</div>
<div id="PVRTools">
<h2>PVRTools</h2>
<p>The PVRTools library consists of various modules designed to facilitate common tasks associated with hardware accelerated graphics rendering. This includes:</p>
<div id="Building">
<h2>Building</h2>
<p>All PowerVR examples for all platforms will build the PowerVR Framework libraries they require. If you use them, or base your own code on them, you should not need to have to build the Framework separately. The PowerVR SDK usually also contains pre-built versions of the libraries in the folder <span class="code">[SDK]/Framework/Bin/[Platform]</span>, where <span class="code">[SDK]</span> is the SDK root and <span class="code">[Platform]</span> is the name of your platform of interest - this is where you would normally link.</p>
<p>All modules can be built separately, by navigating to <span class="code">[SDK]/Framework/[ModuleName]/Build/[Platform]</span>, where <span class="code">[ModuleName]</span> is the name of the specific module of the PowerVR Framework. You can then run a build command as normal for that platform, although this is not required, as building the examples automatically builds the Framework.</span>
</div>
<div id="CreatingAnApplication">
<h2>Creating an Application</h2>
<p>To create a typical application, please follow these steps:</p>
<ol>
<li>Firstly, either build the Framework components previously mentioned (by moving to the corresponding <span class="code">/Builds/[Platform]</span> or add their build scripts and projects to your own</li>
<li>Create a project or build script (Visual Studio, Makefile, etc.) for your platform. We suggest taking one of the scripts from the following location as base:</li>
<p><span class="code">Examples/[Intermediate/Advanced]/[API]/Builds/[Platform]</span>, where <span class="code">[Intermediate/Advanced]</span> is the folder for either the intermediate or advanced example applications supplied with the SDK. In more detail:</p>
<ul>
<li>Add include directories:</li>
<ul>
<li><span class="code">/Framework</span></li>
<li><span class="code">/Builds/Include</span></li>
</ul>
<li>Add library directories:</li>
<ul>
<li><span class="code">Framework/Bin/[Platform]</span></li>
<li>(Optional) <span class="code">/Builds/[Platform]/Lib</span></li>
</ul>
<li>Link against static libraries:</li>
<ul>
<li>(Optional) <span class="code">PVRUIRenderer</span></li>
<li><span class="code">PVR[API]</span></li>
<li><span class="code">PVRPlatformGlue</span></li>
<li><span class="code">PVRShell</span></li>
<li><span class="code">PVRAssets</span></li>
<li><span class="code">PVRCore</span></li>
</ul>
</ul>
<li>Create your application files. For a single CPP file, your includes will usually be:</li>
<ul>
<li><span class="code">PVRShell/PVRShell.h</span></li>
<li><span class="code">PVRApi/PVRApi.h</span></li>
<li><span class="code">PVRApi/AssetManager.h</span> (if you plan to use the AssetManager for loading)</li>
<li><span class="code">PVRUIRenderer/PVRUIRenderer.h</span> (if you plan to use the UIRenderer)</li>
</ul>
<li>Write the skeleton of your application (see description of <a href="#PVRShell" class="link">PVRShell</a>)</li>
</ol>
</div>
<div id="Guidelines">
<h2>Guidelines and Recommendations</h2>
<p>Below are a set of guidelines and recommendations you might want to consider when using PowerVR Framework:</p>
<ul>
<li>If you need to use the native API (for example OpenGL ES), we recommend using the header <span class="code">PVRApi/[API]/[API]Bindings.h</span>. This is a specially crafted binding for your specific API. For example, for OpenGL ES, <span class="code">OpenGLESBindings.h</span> it will provide you with a set of function pointers conveniently placed in the <span class="code">gl::namespace</span>. These functions follow the OpenGL ES specification, and can be called normally e.g. <span class="code">gl::MapBuffer(…)</span>. These function pointers get populated at runtime, allowing a unified entry point to the native API. Similarly, a set of function pointers for extensions are present in the <span class="code">glext</span> namespace. The function pointers get populated at initialisation time, but their use can be queried per-context, at runtime.</li>
<li>Add an AssetManager member to your class and use it for loading Models, Textures, Shaders and other files that may be duplicated. The AssetManager will cache files and make sure you do not double-load files. Initialize the AssetManager with your application class <span class="code">((initialise(*this))</span>, and use it to one-step load Textures, Models, Shaders and other objects that will have to be read from disc.</li>
<li>The <span class="code">pvr::assets::Model</span> class contains all the information you need for drawing, including cameras, lights, and potentially effects. Follow one of the PowerVR SDK examples (e.g. IntroducingPOD and IntroducingPFX) to understand its basic use, including getting out of a Model the information about the data layouts of its Meshes, etc.</li>
<li>Many utility functions and methods are built-in, so that you can easily cover most common use cases. For example:</li>
<ul>
<li><p><strong>Vector, matrix and quaternion mathematics:</strong> Helpers to calculate and operate transformation matrices and other associated mathematical operations.</p></li>
<li><p><strong>OpenGL ES extension handling:</strong> This helps to load and use OpenGL ES extension functions and capabilities.</p></li>
<li><p><strong>3D font drawing:</strong> A very flexible engine to handle font maps.</p></li>
<li><p><strong>POD loader:</strong> Helpers to load and access the model data included in PowerVR Object Data (POD) files.</p></li>
<li><p><strong>PVR loader:</strong> Helpers to upload and manage textures exported to the PVR texture container format.</p></li>
<li><p><strong>PFX loader:</strong> Helpers to load and access PowerVR Effects (PFX) files, which contain vertex and fragment shaders.</p></li>
<li><span class="code">getLayoutIntoPipeline</span> function allows you to quickly match a Mesh to a specific custom shader by providing what your shader's "required semantics" are and at which binding points (attributes) to assign these. This function will add the entire vertex definition to the pipeline descriptor.</li>
<li>This same functionality allows you to simply copy the whole data of the Mesh into a VBO, bind it and draw.</li>
</ul>
<p>The Tools library is used extensively throughout the PowerVR SDK. The PVRTools source can be found in the <a href="../../Tools/">Tools</a> folder in the SDK package. Further documentation is available at <a href="../../Tools/Documentation/Index.html">Tools/Documentation</a>.</p>

<!--API_DESCRIPTION-->
<h1>OpenCL 1.x Examples</h1>
<p>
OpenCL is a cross-platform API for parallel computing on modern processors, including CPUs, GPUs and custom accelerators. It is available both on desktop and embedded platforms, with an embedded profile which is used for more efficient rendering on mobile devices. Rather than being bottlenecked by the CPU, an application can use OpenCL to make use of processors like the GPU that may otherwise remain starved of work, accelerating the application. Also, many workloads that are typically run serially on a CPU are able to complete significantly faster by parallelizing the algorithm and executing them on a GPU. This API is available on PowerVR Series6 GPUs and later.

<p><strong>Description:</strong></p>
<p><p>Alpha testing is a technique through which a test is conducted on a per-fragment basis to determine whether that fragment should be discarded and not contribute to the final scene. This can allow complex shapes to be drawn using very simple geometries, but often at the price of hardware optimisations in the graphics pipeline. In programmable graphics pipelines supporting GLSL this is done through the use of the 'discard' keyword in the fragment shader while in the fixed function pipeline API OpenGL ES 1.x this is performed by calling either glEnable(GL_BLEND) or glEnable(GL_ALPHA_TEST).

<p><strong>Description:</strong></p>
<p><p>Bump mapping is a technique for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during the illumination calculations. The result is an apparently bumpy surface rather than a perfectly smooth surface although the surface of the underlying object is not actually changed. This technique is used extensively in graphics applications to add perceived detail to models without adding further geometry.

<p><p>This training course demonstrates the creation of a reflection effect from a 2D map and a cube map.

Two variations on the technique are shown using either a 2D map or a cube map.

OpenGL ES is a cross-platform API for 2D and 3D graphics on embedded systems such as mobile phones, tablets, vehicles and appliances. It is a subset of desktop OpenGL, tuned to expose the most efficient features of embedded GPUs. OpenGL ES 1.x is the first embedded version of the API, and exposes an efficient, fixed-function pipeline for rendering simpler applications. It is often used for 2D games as the 3D pipeline is more limited than the widely available OpenGL ES 2.x, and it is also used as a basis for teaching engineers about graphics on mobile due to its simpler concepts. If you've never coded OpenGL or OpenGL ES before, it might be useful to start here before moving onto programmable APIs. The examples below will walk you through various basic graphics techniques implemented with OpenGL ES 1.x. This API is available on all current PowerVR GPUs.
<h1>OpenGL ES Examples</h1>
<h3>Programmable pipeline: OpenGL ES 2.0, 3.0 and 3.1</h3>
OpenGL ES is a cross-platform API for 2D and 3D graphics on embedded systems such as mobile phones, tablets, vehicles and appliances. It is a subset of desktop OpenGL, tuned to expose the most efficient features of embedded GPUs.
<p><br><b>OpenGL ES 2.0</b> introduced a programmable pipeline into the API, deprecating a lot of the fixed functionality in OpenGL ES 1.x in favour of programmable shaders. This is the most popular 3D API in existence today, and is widely used in most 3D and many 2D games on mobile and embedded devices. Shaders provide a lot of advanced functionality and flexibility to renderers resulting in substantially more ways to improve graphics fidelity and performance than in OpenGL ES 1.x. Supported on PowerVR Series5 and later</p>
<p><br><b>OpenGL ES 3.x</b> adds to the already powerful OpenGL ES 2.0 things such as multiple render targets, standardised texture compression, a new shading language and far more control over texturing. OpenGL ES 3.1 also adds compute shaders and advanced compute functionality, allowing General Purpose on GPU (GPGPU) processing. Supported on PowerVR Series6 and later</p>
<p>The descriptions below specify the minimum API version the demo has been written for. When more than one version are listed, there is differentiated code for each of them. For example, OpenGL ES 2.0/3.0 will have two different versions, one of them will make use of OpenGL ES 3.0 specific features.</p>

<p>This training course demonstrates how to use the PVRApi library to render a scene from a pod file, using a .pfx effect file. PFX is both a file format and an API, and stands for PowerVR Effects. The library loads the POD file and the PFX file separately, creates a PVRAssets Model from the POD and a PVRApi Effect from the PFX file, and combines them to render the scene using the PVRApi necessary objects. Uses the PVRUIRenderer library to display simple text on screen. Different Shader versions provided for OpenGL ES 2.x and 3.x.

<p><p>This training course introduces the Print3D class from the PVRTools library. Print3D can be used to display text in both 2D and 3D modes. The default projection mode is 2D but supplying a modelview and projection matrices allow the user to render the text in 3D. Text in different colours is also possible.
</p></p>
<p>This training course introduces the PVRUIRenderer framework library.The user can create "Sprites" (2D elements) which can be grouped in 2D and/or 3D groups to be displayed as UI's or world text. 2D transformations (pixel and/or NDC coordinates) both single and in a group, anchoring on different parts of the screen or the group and 3D transformations of groups of sprites are all possible.
In this example, UIRendererer is used to display images and Unicode text, screen aligned and with 3D transformations.

<p><p>This demo illustrates various shadow techniques, such as the dynamic blob method which draws a transparent blob under the character and the blob moves based on the centre of the object. The projected geometry method draws the object "projected" onto the floor plane, only pure black shadows are possible due to multiple polygons being projected into the same location (would give intensity differences in the shadow if transparency would be used). The final method is a projected texture where the projected shadow texture is updated dynamically each frame (generated by rendering the scene from the point of view of the light source).

<p><strong>Description:</strong></p>
<p><p>This demo illustrates the visual difference between the following different texture filter modes: GL_LINEAR (Bilinear with no MIPMapping), GL_LINEAR_MIPMAP_NEAREST (Bilinear with MIPMapping), GL_LINEAR_MIPMAP_LINEAR (Trilinear).
</p></p>
<p>Bump mapping is a technique for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during the illumination calculations. The result is an apparently bumpy surface rather than a perfectly smooth surface although the surface of the underlying object is not actually changed. This technique is used extensively in graphics applications to add perceived detail to models without adding further geometry.
This example can be used as the baseline for rendering an object. Uses different shaders for OpenGL ES 2.x and OpenGL ES 3.x

<p><p>Cell-Shading is the "art" of rendering your objects to look like cartoons. This demo shows a dancing mouse with a hard black outline and banded shading to achieve the desired cartoon-look. Both effects are set up using optimised software routines.
</p></p>
<p>Traditional rendering algorithms submit geometry and immediately apply shading effects to the rasterized primitives. Complex shading effects may require multiple render passes to produce the final pixel color, with the geometry submitted every pass. Deferred shading is an alternative rendering technique that submits the scene geometry once, storing per-pixel attributes into local video memory to be used in the subsequent rendering passes.
In these later passes, light volume primitives are rendered, and the per-pixel attributes contained in the buffer are retrieved at a 1:1 mapping ratio so that each pixel is shaded individually.
In the PowerVR architecture, the user can use fast on-chip memory instead of Multiple Render Targets, by utilising the Pixel Local Storage extension.
If running from a command line, add -forcemrt to force Multiple Render Targets rendering.
Requires at least OpenGL ES 3.0 capability for either MRT or PLS. Requires the extension GL_EXT_shader_pixel_local_storage for PLS.

<p><strong>Description:</strong></p>
<p><p>This demo illustrates the Polybump technology developed by Crytek to enhance 3D-rendering quality without increasing the overhead in real-time rendering. It allows users to create and render an extremely low poly model using per pixel DOT3 lighting. The DOT3 NormalMap is automatically generated from a high poly model. As a result when displaying the low polygon model with the DOT3 map generated from the high polygon object there is virtually no visible difference between the two. Rendering time is greatly decreased and bandwidth is compressed. In this demo a model of a detailed human head is show even though there are only 276 polygons in the model.

<p>The demo utilises GPGPU (GPU Compute) to implement a particle system, which advanced and then rendered every frame, without any CPU editing of the data. Particle systems are techniques that use a large amount of sprites to simulate phenomena that would be difficult to reproduce with conventional rendering techniques. Furthermore, it also highlights the interaction between the Compute and the Rendering part of a simulation.

<p><strong>Description:</strong></p>
<p><p>This demo shows a transparent vase with dynamic reflections on its metallic sections. The effect is achieved through a mixture of texturing blending, and a two pass render that draws both the back and front face of the glass object separately with different culling modes.
</p></p>
<p>The Skinning demo shows a Skinned Character in combination with bump mapping. Skinning is the act of animating a vertex over time given a set (palette) of matrices and a known set of blend weights assigned to those matrices. For each frame the Matrix Palette is recomputed based on time. PVRAssets and POD files support skinning. either full transformation Matrices, or Quaternion rotation with Scaling and Translation vectors. The provided POD file contains matrix animation.
This example is using BoneBatching, which separates the mesh in smaller matrix palettes (Bone Batches) so that they can fit in the maximum number of allowed Uniform variables.
Up to 4 matrices from the palette, along with 4 weights can used for each vertext by the vertex shader to update the position to obtain the current animation frame position.
Shaders provided for OpenGL ES 2.0 and OpenGL ES 3.0

<!--API_DESCRIPTION-->
<h1>OpenGL ES 2.0 Examples</h1>
<p>
OpenGL ES is a cross-platform API for 2D and 3D graphics on embedded systems such as mobile phones, tablets, vehicles and appliances. It is a subset of desktop OpenGL, tuned to expose the most efficient features of embedded GPUs. OpenGL ES 2.0 introduces a programmable pipeline into the API, deprecating a lot of the fixed functionality in OpenGL ES 1.x in favour of programmable shaders. This is the most popular 3D API in existence today, and is widely used in most 3D and many 2D games on mobile and embedded devices. Shaders provide a lot of advanced functionality and flexibility to renderers resulting in substantially more ways to improve graphics fidelity than in OpenGL ES 1.x. The examples below both reproduce techniques in OpenGL ES 1.x using shaders, and also describe a number of other more advanced techniques. This API is available on all current PowerVR GPUs.

<p><strong>Description:</strong></p>
<p><p>Alpha testing is a technique through which a test is conducted on a per-fragment basis to determine whether that fragment should be discarded and not contribute to the final scene. This can allow complex shapes to be drawn using very simple geometries, but often at the price of hardware optimisations in the graphics pipeline. In programmable graphics pipelines supporting GLSL this is done through the use of the 'discard' keyword in the fragment shader while in the fixed function pipeline API OpenGL ES 1.x this is performed by calling either glEnable(GL_BLEND) or glEnable(GL_ALPHA_TEST).

<p><strong>Description:</strong></p>
<p><p>Bump mapping is a technique for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during the illumination calculations. The result is an apparently bumpy surface rather than a perfectly smooth surface although the surface of the underlying object is not actually changed. This technique is used extensively in graphics applications to add perceived detail to models without adding further geometry.

<p><p>This training course demonstrates the use of environment mapping with perturbed UVs. For any given surface on the object a normal map value is read, an angle of reflection between that normal and the eye direction is used to generate a new UV co-ordinate and finally, this UV co-ordinate is used to find the correct colour to reflect from the environment map.

<p><strong>Description:</strong></p>
<p><p>This training course demonstrates the creation of a reflection effect from a 2D map and a cube map. This technique is also known as environment mapping in that the environment around an object is rendered into a texture (in this case as a pre-baked step) and then this environment is sampled per fragment in order to simulate the effect of light from the environment being reflected from the object. Two variations on the technique are shown using either a 2D map or a cube map.

A number of operators are supplied and descriptions are included with the PFX file. The example allows the user to alter the exposure of the image by a number of stops, demonstrating the usefulness of floating point textures.

For each frame the Matrix Palette is recomputed based on time. Per vertex, up to 3 matrices, from the palette, along with 3 weights are used by the vertex shader to update the vertex position to obtain the current animation frame position. Two lighting modes are available; per vertex lighting, and bump mapped lighting.

<p><strong>Description:</strong></p>
<p><p>Spherical Harmonic lighting is a real-time rendering technique that uses a pre-processing step to realistically render scenes using any type of light source. It is primarily used to reproduce diffuse lighting. The diffuse vertex lighting requires at least four light sources to to be roughly equivalent to the spherical harmonics lighting for this scene. Implementing four diffuse lights requires more vertex shader instructions than the spherical harmonics calculations.

<!--API_DESCRIPTION-->
<h1>OpenGL ES 3.x Examples</h1>
<p>
OpenGL ES is a cross-platform API for 2D and 3D graphics on embedded systems such as mobile phones, tablets, vehicles and appliances. It is a subset of desktop OpenGL, tuned to expose the most efficient features of embedded GPUs. OpenGL ES 3.x adds to the already powerful OpenGL ES 2.0 with things such as multiple render targets, standardised texture compression, a new shading language and far more control over texturing. OpenGL ES 3.1 also adds compute shaders and advanced compute functionality, allowing General Purpose on GPU (GPGPU) processing. OpenGL ES 3.x is the most advanced embedded graphics API available today, and provides many features previously only found on desktop systems. This API is used by developers who want to target cutting edge devices and provide console quality entertainment on mobile systems. This API is available on PowerVR Series6 GPUs and later.

This can allow complex shapes to be drawn using very simple geometries, but often at the price of hardware optimisations in the graphics pipeline. In programmable graphics pipelines supporting GLSL this is done through the use of the 'discard' keyword in the fragment shader while in the fixed function pipeline API OpenGL ES 1.x this is performed by calling either glEnable(GL_BLEND) or glEnable(GL_ALPHA_TEST).

<p><strong>Description:</strong></p>
<p><p>In this training course two techniques are shown for generating an anisotropic lighting effect (the effect of surface grain on materials such as brushed metal, velvet etc.). The first technique uses per vertex and pixel calculations to calculate the shading and thus generate the effect on the fly. The second technique uses a texture lookup to determine the shading and would be useful in situations where bandwidth was more readily available than processing time.

<p><strong>Description:</strong></p>
<p><p>Bump mapping is a technique for simulating bumps and wrinkles on the surface of an object. This is achieved by perturbing the surface normals of the object and using the perturbed normal during the illumination calculations. The result is an apparently bumpy surface rather than a perfectly smooth surface although the surface of the underlying object is not actually changed. This technique is used extensively in graphics applications to add perceived detail to models without adding further geometry.

This is very similar to normal bump mapping but with the addition of a parallax effect based on the view vector. This training course serves as an example of implementing the parallax bump mapping effect.

<p><p>This training course demonstrates the use of environment mapping with perturbed UVs. For any given surface on the object a normal map value is read, an angle of reflection between that normal and the eye direction is used to generate a new UV co-ordinate and finally, this UV co-ordinate is used to find the correct colour to reflect from the environment map.

<p><strong>Description:</strong></p>
<p><p>This training course demonstrates the creation of a reflection effect from a 2D map and a cube map. This technique is also known as environment mapping in that the environment around an object is rendered into a texture (in this case as a pre-baked step) and then this environment is sampled per fragment in order to simulate the effect of light from the environment being reflected from the object. Two variations on the technique are shown using either a 2D map or a cube map.

<p><strong>Description:</strong></p>
<p><p>Spherical Harmonic lighting is a real-time rendering technique that uses a pre-processing step to realistically render scenes using any type of light source.

Implementing four diffuse lights requires more vertex shader instructions than the spherical harmonics calculations.

<h2>PowerVR Tools and SDK v4.0</h2>
<h3>Overview</h3>
<p>In this release, we aim to ease developers into the new generation of graphics APIs with our new Framework. It is a completely re-written cross-platform and cross-API framework which functions as scaffolding around which to build your own rendering or game engine. In addition to this, we have improved all of our utilities, though PVRTrace is the utility which has had the most changes – not only does it feature a large number of bug-fixes and back-end enhancements, but also a redesigned Scrubber for much improved Image Analysis. PVRTrace now also supports the Android Extension Pack. It also bears mentioning that PVRHub now is compatible with Android 6.0 Marshmallow, and it has been redesigned to support Android TV.</p>
<h3>General</h3>
<ul>
<li>Updated EULA to separate PowerVR SDK (now under MIT licence) and PowerVR Tools (with a revised free license)</li>
</ul>
<h3>Examples</h3>
<ul>
<li>Ported a core of relevant SDK examples to be targeting the new PowerVR Framework</li>
<li>Examples are still classified by beginner, intermediate and advanced levels</li>
<li>Examples are now built per API family instead of per API version. At the moment, OpenGL ES Programmable pipeline (2.0+) is provided.</li>
<li>Platform max supported API version is now checked at runtime, usually creating the latest possible OpenGL context version unless otherwise instructed</li>
<li>Revamped the look and feel of the SDK examples by using new themes and assets</li>
</ul>
<h3>Framework</h3>
<ul>
<li>Brand new PowerVR Framework, replacing the PVRShell and PVRTools. The new framework consists of separate libraries providing groups of functionality as modules. These modules are PVRCore, PVRAssets, PVRShell, PVRPlatformGlue, PVRApi, PVRUIRenderer and PVRCamera</li>
<li>PVRCore provides support for the other modules</li>
<li>PVRShell provides platform abstraction/entry point (replaces the old PVRShell)</li>
<li>PVRPlatformGlue provides platform/API joining functionality to PVRShell</li>
<li>PVRApi provides an API abstraction on top of which to build the example (replacing PVRTools)</li>
<li>PVRUIRenderer provides 2D element drawing/layout functions (replaces the old tools Print3D)</li>
<li>PVRCamera provides HW Camera abstractions (replaces the CameraModule)</li>
<li>Uses C++ (namespacing, smart pointers, OOP), the C++ standard library, GLM for maths</li>
</ul>
