Picogen is a rendering system for the creation and rendering of artificial terrain, based on ray tracing. It is free software.
Overview
[edit | edit source]While the primary purpose of picogen is to display realistic 3D terrain, both in terms of terrain formation and image plausibility, it also is a heightmap-creation tool,[1] in which heightmaps are programmed in a syntax reminiscent of Lisp.[2]
The shading system is partially programmable.[3]
Example features
[edit | edit source]- Whitted-Style ray tracer for quick previews
- Rudimentary path tracer for high quality results
- Partial implementation of Preetham's Sun-/Skylight Model [4]
- Procedural heightmaps, though before rendering they are tesselated
Frontends
[edit | edit source]Currently there is a frontend to picogen, called picogen-wx (based on wxWidgets). It is encapsulated from picogen and thus communicates with it on command-line level. Picogen-wx provides several panels to design the different aspects of a landscape, e.g. the Sun/Sky- or the Terrain-Texture-Panel. Each panel has its own preview window, though each preview window can be reached from any other panel.
Landscapes can be loaded and saved through an own, simple XML-based file format, and images of arbitrary size (including antialiasing) can be saved.
