An interactive application for sculpting in 3D.
Distance functions defining the surface of a shape can be added additively and subtractively to form complex shapes. Functions are added to an octree which causes affected areas to be re-evaluated. Function evaluation consists of iterating over a hierarchical grid to find distances smaller than some threshold. Zero-crossing points are collected and uploaded to an openGL vertex buffer, then drawn.
