Speech description

 

Reducing the amount of occluded geometry submitted to the GPU is crucial for efficient rendering. This is especially true for

games with a large number of props, where the developer has no total control of the content/level design, like UGC games.

This talk summarises the state of the art and describes practical approaches in GPU based occlusion culling combined with GPU driven

rendering, intended for SkySaga:Infinite Isles.”
