| Color buffer clears |
| |
| Tests: |
| + dEQP-GLES2.functional.color.clear.* |
| |
| Includes: |
| + Full-screen color buffer clears: glClear(), glClearColor() |
| + glScissor() effect on color buffer clears |
| + glColorMask() effect on color buffer clears |
| + Combined glScissor() and glColorMask() effect |
| |
| Excludes: |
| + glViewport() effect on color buffer clears |
| + Out-of-rande inputs for glClearColor() |
| + Depth and stencil buffer clears |
| |
| Description: |
| |
| Color clear tests are organized based on the feature set used in the |
| test case. Each test case performs multiple iterations, each consisting |
| of multiple color clears. Parameters, such as color, scissor rectangle |
| or color mask are chosen using deterministic random number generator. |
| |
| Results are verified by building a reference image and comparing it |
| against the rendered image at the end of each iteration. |
