The results are compared to verify correctness. 40 41 Rendering is ordered so that all occlusion queries are started before any 42 conditional rendering is done. 43 44 Call count test use many occlusion queries and simple occluder geometry. Every 45 second occlusion query is set to fail. Failing occlusion query geometry is 46 limited within a small region of the screen. Passing query geometry is evenly 47 spread around the screen. Conditionally rendered geometry is evenly spread. 48 49 Distant query tests have maximal screen distance between the query geometry 50 and the rendering the query controls. The setup is equivalent to the call 51 count cases with the exception of the distribution of the primitives rendered. 52 Occlusion query geometry is roughly on the opposing edge of the screen as the 53 geometry it controls. All edges have occluders.
