Clustered rendering

Todo: Document bit more about this technique.

Clustered rendering (or Clustered shading), is a technique, similar to Deferred renderer, allows dynamic lights to be rendered with little to no performance impact.

Differences from deferred renderer

The differences with deferred is that clustered can be implemented in both forward and deferred renderers. This also allows the usage of sharper, but more expensive MSAA anti-aliasing (which are harder to implement, poor results with lower performance or simply unfeasible on deferred renderer).

Todo: More?

Usage

Source

The following Source games or branches use this technique:

• Strata Source use cluster forwards render (forwards+)
  • Portal 2: Community Edition (currently available via clustered beta branch).
  • Momentum Mod (currently available via 0.10.0-pre29 beta branch)
• Operation: Black Mesa use a hybrid render between cluster deferred render and cluster forwards render
