Clustered Forward Rendering - First Performance Metrics
From the blog "Josh's Dev Blog"
I was able to partially implement clustered forward rendering. At this time, I have not divided the camera frustum up into cells and I am just handing a single point light to the fragment shader, but instead of a naive implementation that would just upload the values in a shader uniform, I am going through the route of sending light IDs in a buffer. I first tried texture buffers because they have a large maximum size and I already have a GPUMemBlock class that makes them easy to work with. Becau
