Lego Tutorial by Archee [web]
Lego tutorial by Archee 4KB procedural image for NVscene 2014 Features fuzzy specular reflections, diffusion, indirect lighting, refraction (glass) and motion blur using montecarlo. This is not raymarching. The intersection of the ray with the objects is caluclated by solving the intersection equations, and then chosing the closest intersection. A hierarchy tree is based on bounding spheres with branching. 3D CSG boolean is used to create shapes from quadratic functions and planes. Diffusive surfaces reflect the ray in a random diretion or in random occasions in the specular direction. One big shader takes 20 seconds to compile. As you see the size is far below 4K, but adding more to the scene would make shader compilation slow. The rest of the time is used to shoot the scene with photons from the camera point of view. The faster GPU you have, the less noizy result you get after all the 58seconds are past. Needs full HD screen to run. 1920x1080 run leg_compatible_fullhd.exe to see rendering in progress. thx to Crinkler
