Unnormalized texture coordinates · 036cc9aeAlexis Hetu authored
Unnormalized texture coordinates are pretty much the same as rectangle texture coordinates, with a few extra addressing modes to support. ADDRESSING_CLAMP and ADDRESSING_BORDER work properly. Other modes can't used with unnormalized texture coordinates, according to the Vulkan spec: "If unnormalizedCoordinates is VK_TRUE, addressModeU and addressModeV must each be either VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_EDGE or VK_SAMPLER_ADDRESS_MODE_CLAMP_TO_BORDER" Bug b/129523279 Change-Id: I3e39c16172bc5825ec48c6395f52e9b177df1304 Tests: dEQP-VK.texture.filtering.unnormal.* Reviewed-on: https://swiftshader-review.googlesource.com/c/SwiftShader/+/31648Tested-by:
