| Texture swizzle tests |
| |
| Tests: |
| + dEQP-GLES3.functional.texture.swizzle.* |
| |
| Includes: |
| + All texture swizzle modes applied separately for each channel |
| + Randomized swizzle mode combinations |
| + RED, RG, RGB, RGBA, A, L, LA texture formats |
| |
| Excludes: |
| |
| Description: |
| |
| Texture format tests render a single quad, consisting of two triangles. |
| The viewport is configured to match the texture size. Texture coordinates |
| yield a 1:1 mapping from texels to framebuffer pixels. Thus filtering |
| shouldn't affect the final rendered image. |
| |
| The rendered image is compared against a reference that is produced by |
| reference renderer. A simple threshold-based comparison is used. |
