%description
Render scenes using pathtracing. Build 3D scenes out of spheres, cubes,
planes, disks, triangles, cones, curves, line segments, cylinders,
ellipsoids, and 3D models in the 'Wavefront' OBJ file format or the PLY
Polygon File Format. Supports several material types, textures, multicore
rendering, and tone-mapping. Based on the "Ray Tracing in One Weekend"
book series. Peter Shirley (2018) <https://raytracing.github.io>.
