| // Each test generates an image with a color gradient where all colors should be unique when rendered without density map |
| // ( the number of each color in a histogram should be 1 ). |
| // The whole density map has the same values defined by input fragment area ( one of the test input parameters ). |
| // With density map enabled - the number of each color in a histogram should be [ fragmentArea.x * fragmentArea.y ]. |
| // |
| // Additionally test checks if gl_FragSizeEXT shader variable has proper value ( as defined by fragmentArea input parameter ). |
| // |
| // static_* tests use density map loaded from CPU. |
| // dynamic_* tests use density map rendered on a GPU in a separate render pass |
| // *_nonsubsampled tests check if it's possible to use nonsubsampled images instead of subsampled ones |
| // There are 3 render passes performed during the test: |
| // - render pass that produces density map ( this rp is skipped when density map is static ) |
| // - render pass that produces subsampled image using density map |
| // - render pass that copies subsampled image to traditional image using sampler with VK_SAMPLER_CREATE_SUBSAMPLED_BIT_EXT flag. |
| // ( because subsampled images cannot be retrieved to CPU in any other way ). |
