Picogen is an outdoor Monte Carlo ray tracing system designed to render large-scale terrain with realistic day/night-illumination and detailed plant populations. It also is a heightmap-creation tool, in which heightmaps are programmed in a syntax that reminds of LISP.
- Whitted-Style Ray Tracer for quick previews
- Rudimentary path tracer for high quality results
- Partial implementation of Preetham's Sun-/Skylight Model
- Procedural Heightmaps, though before rendering they are tesselated
