| Description: |
| |
| Conditional rendering stress tests use a large number of conditional rendering |
| calls under various conditions. |
| |
| Call count and distant query tests prepare all vertex arrays before rendering. |
| All tests are based on using occlusion queries with known results and rendering |
| the same scene with geometry culled either by conditional rendering or the |
| test logic. The results are compared to verify correctness. |
| |
| Rendering is ordered so that all occlusion queries are started before any |
| conditional rendering is done. |
| |
| Call count test use many occlusion queries and simple occluder geometry. Every |
| second occlusion query is set to fail. Failing occlusion query geometry is |
| limited within a small region of the screen. Passing query geometry is evenly |
| spread around the screen. Conditionally rendered geometry is evenly spread. |
| |
| Distant query tests have maximal screen distance between the query geometry |
| and the rendering the query controls. The setup is equivalent to the call |
| count cases with the exception of the distribution of the primitives rendered. |
| Occlusion query geometry is roughly on the opposing edge of the screen as the |
| geometry it controls. All edges have occluders. |
