Adding more geometric primitives to our "Simple Ray Tracer"

August 24, 2018

Adding more primitives and learning about the dreaded ray tracing "acne" caused by finite precision issues with computing ray-shape intersections. All rendering in the above movie is done in CUDA on a Titan V.  Unfortunately the youtube compression algorithm is a lit harsh for the above movie. 

 

A lot of useful material is available online:

 

1. great tutorial: https://www.scratchapixel.com

2. useful list of common raytracing mistakes: https://geekshavefeelings.com/posts/mistakes-to-make-on-a-raytracer 

3. finding the intersection of a ray and a cone: http://lousodrome.net/blog/light/2017/01/03/intersection-of-a-ray-and-a-cone/
