Procedural 3D Cave Generator
Procedural 3D Cave Generator for Java based 3D engines: JMonkeyEngine and Ardor3D. Cave geometry is generated in CPU, so this is not using geometry shaders.
Many technical ideas are got from GPU Gems 3: Chapter 1. Generating Complex Procedural Terrains Using the GPU. http://http.developer.nvidia.com/GPUGems3/gpugems3_ch01.html
