Structure Synth
Simple Fractal in Structure Synth
Structure Synth is an application to generate 3D structure using a design grammar. Design grammar is a script with some rules. These rules decide final output. This page contains scripts that generate fractal like structure. The output can be exported in different file formats and rendered in Blender, Renderman, Sunflow and Povray.
