31e5c31af7Sopenharmony_ciDescription:
32e5c31af7Sopenharmony_ci
33e5c31af7Sopenharmony_ciOcclusion query stress tests generate large amounts of occlusion queries
34e5c31af7Sopenharmony_ciin order to test implementation's ability to handle them. First a
35e5c31af7Sopenharmony_cispecified number of occluding triangles are drawn. Then the occlusion
36e5c31af7Sopenharmony_ciquery is started, specified number of target triangles are drawn and the
37e5c31af7Sopenharmony_ciocclusion query is terminated. After all occlusion queries and triangle
38e5c31af7Sopenharmony_cidraws are executed, glFinish() is called and all query results are read.
39e5c31af7Sopenharmony_ci
40e5c31af7Sopenharmony_ciActual query result values are not verified - only trouble-free result
41e5c31af7Sopenharmony_ciretrieval is tested. Query result correctness can be implemented later
42e5c31af7Sopenharmony_ciby inspecting framebuffer contents.
