Procedural Geometric Synthesis on the GPU

Manuscript accompanying poster at GP^2: The ACM Workshop on General Purpose Computing on Graphics Processors, and SIGGRAPH 2004 poster, Aug. 2004

We present a framework for translating procedural production rules, such as parametric L-Systems based on scene graphs instead of turtle graphics, into a form that can iteratively grow geometry completely on graphics hardware. The formulation is extended to handle context-sensitive, conditional and non-deterministic rules. We also examine and enhance existing GPU-based techniques for bitonic merge sorting. The result is procedural geometry synthesized directly on the graphics card.
