Dmitry Stepanov 4786663d9a use uniform visibility buffer to improve cache utilization 
- pass object count in each tile to gpu and not over-iterate there

Dmitry Stepanov eecfc18e4d use rgba8 pixel format for visibility buffer intead of r32f 
- floating point has 23 bits of mantissa, thus it's "binary" precision is limite to that bit count, rgba8 has 32 bit precision which is quite significant
 2024-08-28 14:34:54 +03:00
Dmitry Stepanov 6ecced47d0 removed redundant memory allocations each frame 2024-08-27 19:13:14 +03:00
Dmitry Stepanov 98b63b1b53 reduced tile size for better gpu parallelism 2024-08-27 18:40:36 +03:00
Dmitry Stepanov 32a350a8a8 use visibility test data from previous frame 
- this is needed, because occlusion culling algorithm uses depth buffer from previous frame and it also must use bounding boxes and view/projection matrices from the previous frame as well
- removes frame coherence problem, by the cost of 1 frame lag in occlusion test
 2024-08-27 18:05:09 +03:00
Dmitry Stepanov 353a7e78fc switch to enable/disable occlusion culling 2024-08-27 12:42:32 +03:00

 2024-08-27 11:56:32 +03:00
Dmitry Stepanov d06e9e91de fixed aabb -> screen projection 
- handle cases when points go behind near clipping plane
 2024-08-27 11:55:33 +03:00
Dmitry Stepanov 79413a95fd optimize visibility buffer on gpu before reading it on cpu 
- collapses fullscreen visibility buffer into (w_tiles X h_tiles) buffer, and essentially moves 98%+ of computational complexity to GPU
 2024-08-26 20:39:47 +03:00
Dmitry Stepanov 08b50aef9d finished first iteration of occlusion culling algorithm
