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.
