Main lit rendering effectively mixes Forward+ with Visibility Buffer style rendering approaches or optimal performance.

Deferred+: Next-Gen Culling and Rendering for Dawn Engine

WebA subsequent compute shader generates, from the acquired visibility information, the data which is used for indirect rendering. As proposed by [Haar and Aaltonen 15], occluded objects are retested with the updated depth buffer from the current frame to avoid missing false negatives. Figure 1 gives an overview of the involved steps and resources.

The two triangles have poor quad utilization -- left is too small, right is too thin. The 10 red quads touched by the triangles need to be completely shaded, even though the 12 green pixels are the only ones that are actually needed. Overall, 70% of the GPU's work is wasted. fabrice bochet

"WebJun 5, 2001 · The idea I had was: Every triangle knows the material it will be rendered with. Then, during visibility, each visible triangle (or group of tris) is sent (copied) to a render buffer for the material. If the render buffer is full, then I would render it using compiled vertex arrays. So, every material has its own render buffer. " - Triangle visibility buffer

Unreal Engine provides methods of culling for visibility and occlusion. These culling methods are useful for optimizing game performance. Each method works to reduce the number of visible Actors in the Level by setting whether they should be drawn to the screen or not.
