Detailed Description

The light module manages light data buffers and light culling system.

The culling follows the principles of Tiled Culling + Z binning from: "Improved Culling for Tiled and Clustered Rendering" by Michal Drobot http://advances.realtimerendering.com/s2017/2017_Sig_Improved_Culling_final.pdf

The culling is separated in 4 compute phases:

• View Culling (select pass): Create a z distance and a index buffer of visible lights.
• Light sorting: Outputs visible lights sorted by Z distance.
• Z binning: Compute the Z bins min/max light indices.
• Tile intersection: Fine grained 2D culling of each lights outputting a bitmap per tile.
