Can someone point to a resource/tutorial for learning point splatting (the 90s rendering technique)? Gaussian Splatting has completely over taken the search results, and the original technique is now near impossible to find.

Westover’s thesis https://www.cs.unc.edu/techreports/91-029.pdf

It's going to be even more impossible to find now because the present paper introduces "Gaussian point splatting".
