A Quick Crash Course on Ray Marching
Wait, this isn’t a post on Ray Tracing? Well not quite, I don’t mean “ray tracing” in the sense of scene rendering in computer graphics. My research is based on some very specific optical devices and I am interested in how geometry impacts their performance.
Ray tracing is typically complicated, but ‘Ray Marching’ is a simplified way to achieve a very similar result.
What I’m interested in “ray tracing” is the optical path a single ray will take inside the device - so by running Monte-Carlo simulations I can estimate the statistical nature of the device (exit angle, exit location, optical path length and more).
