Raytracing is one of my major areas of interest. At it's most basic, it's a process to figure out where a ray hits an object. There's a lot of different applications, a big one is simulating light behavior via pathtracing. Even within pathtracing, there's a lot of variation. Rays can go from the eye towards light sources, in the typical pathtracing approach, or from the light source in the case of forward pathtracing. I have had a lot of fun putting together my larger pathtracing projects, Siren and Daedalus. These posts are mostly about smaller one-offs that I messed with briefly, trying stuff out.
