Game Engine Programming 059.2 - Optimizing Forward+: using bounding spheres | C++ Game Engine
✅ Support Game Engine Series / gameengineseries
In the last video we cleaned up the C++ code for lighting as well as fixed a few bugs. So, now we're ready to optimize the light-culling shader, which is going to be the topic for the rest of this episode.
