"HBSurf" is a Hierarchical B-Spline modeler very similar to the one described by David R. Forsey and Richard H. Bartels in their SIGGRAPH '88 paper, Hierarchical B-Spline Refinement." It allows a user to create smooth patches of surface with fine details and export these patches to files that can be rendered by the public domain ray-tracer, POV-ray.
This modeler is "hierarchical" because it allows points on the patches surface to be manipulated at many "levels." At a low level, moving points on the surface will create large bulges around those points. At a higher level, moving those same points will create smaller bulges. Thus, manipulating points creates "coarse" changes at low levels and "fine" changes at high levels.
This modeler was created as a class project for a Computer Aided Geometric Modeling class. Its interface is rather clunky, but, with some patience, it can be used to create very detailed surface patches for use with POV-ray, or just for kicks!
