31*35238bceSAndroid Build Coastguard WorkerDescription:
32*35238bceSAndroid Build Coastguard Worker
33*35238bceSAndroid Build Coastguard WorkerConditional rendering stress tests use a large number of conditional rendering
34*35238bceSAndroid Build Coastguard Workercalls under various conditions.
35*35238bceSAndroid Build Coastguard Worker
36*35238bceSAndroid Build Coastguard WorkerCall count and distant query tests prepare all vertex arrays before rendering.
37*35238bceSAndroid Build Coastguard WorkerAll tests are based on using occlusion queries with known results and rendering
38*35238bceSAndroid Build Coastguard Workerthe same scene with geometry culled either by conditional rendering or the
39*35238bceSAndroid Build Coastguard Workertest logic. The results are compared to verify correctness.
40*35238bceSAndroid Build Coastguard Worker
41*35238bceSAndroid Build Coastguard WorkerRendering is ordered so that all occlusion queries are started before any
42*35238bceSAndroid Build Coastguard Workerconditional rendering is done.
43*35238bceSAndroid Build Coastguard Worker
44*35238bceSAndroid Build Coastguard WorkerCall count test use many occlusion queries and simple occluder geometry. Every
45*35238bceSAndroid Build Coastguard Workersecond occlusion query is set to fail. Failing occlusion query geometry is
46*35238bceSAndroid Build Coastguard Workerlimited within a small region of the screen. Passing query geometry is evenly
47*35238bceSAndroid Build Coastguard Workerspread around the screen. Conditionally rendered geometry is evenly spread.
48*35238bceSAndroid Build Coastguard Worker
49*35238bceSAndroid Build Coastguard WorkerDistant query tests have maximal screen distance between the query geometry
50*35238bceSAndroid Build Coastguard Workerand the rendering the query controls. The setup is equivalent to the call
51*35238bceSAndroid Build Coastguard Workercount cases with the exception of the distribution of the primitives rendered.
52*35238bceSAndroid Build Coastguard WorkerOcclusion query geometry is roughly on the opposing edge of the screen as the
53*35238bceSAndroid Build Coastguard Workergeometry it controls. All edges have occluders.
