WebDec 8, 2024 · I have a custom sphere of 1 million plus vertices that I'm using for an interactive. Looping through 1M+ points per mouse movement is exceedingly costly so I've decided to leverage frustum culling. This helps but all the points on the back-facing side of the sphere are still being looped through which is still very costly.
