Spectral Ray Tracing
2024-04-13 I’m sharing this to give some background on my recent artworks exploring light, color, and perception through spectral ray tracing. This ray tracer that I’ve written has shown up in a few of my series, and I wanted to explain what “spectral ray tracing” even is.
This is physically sound under our current model of the universe, as we assume the laws governing light transport are symmetric with respect to the direction of time (a.k.a. For example: yellow has a corresponding wavelength as seen in the above visible spectrum at around 580nm, but it can also be reproduced with a mix of red and green light (as it must be, given that the diagram itself is being rendered using only RGB values on a computer monitor).
