Ambient Occlusion - yvt/openspades GitHub Wiki
When r_radiosity
is set to 1
, OpenSpades renderer does large scale ambient occlusion. This takes more blocks in account than the [default ambient occlusion](Simple Ambient Occluson) does, making itself more suitable to simulate the shadow of sky light.
Computation is done in CPU in background, and the computation result is streamed to VRAM.
- Requires 16MB of VRAM.
- CPU must be fast enough to compute the ambient occlusion reasonably fast.
