Analytic Drawing of 3D Scaffolds

Novel techniques for computer-assisted analytic drawing of 3D scaffolds. Geometric constraints derived from the scaffold allow precise 3D geometry to be inferred from sketched stroke input.

Approximating Subdivision Surfaces With Gregory Patches for Hardware Tessellation

A new method of approximating Catmull-Clark subdivision surfaces with Gregory patches is. These patches are easily accelerated by the new Direct3D 11 hardware tessellator, resulting in excellent performance.
