Game Engine Programming 057.2 - Tile-based light culling: dispatch compute shader | C++ Game Engine
✅ Support Game Engine Series / gameengineseries
Previously we wrote our very first compute shader for Primal Engine, which will be used to compute a grid of frustums for light culling. Today we're going to set up the data and buffers that are needed, and try to run this shader by calling the dispatch function.
