Requires:
- OpenGL 2.1
- Fast GPU; takes ~10 seconds to generate multisample images, or about 100..1000 ms for individual samples on Titan-class cards
Contains:
- compute pipeline using fragment shaders, with textures bound to framebuffers as in/out
- multioctave value noise terrain generator and hydraulic erosion (erosion is turned off for the party version build due to size limitations)
- mixed heightmap and signed distance field raymarcher
- atmosphere scattering (rayleigh + mie)
- monte-carlo global illumination (path tracing)
Can be used to produce images like this:
or this:
Supported platforms:
- Windows (target compo platform): viewer only
- Mac OS X (used for development): shader livecoding tool
- Linux (used for development): shader livecoding tool and wsad+mouselook
I have no plans to continue development or support this, but may occasionally play with it and tweak things out of boredom.
Released under WTFPL.
