Relief Analysis and Extraction

Extracting relief and details from surfaces by separating them into a base function and a height function. This approach estimates the height function without explicitly extracting the base surface.

Packing Circles and Spheres on Surfaces

Triangle meshes whose faces form a packing are a rich source of geometric structures relevant to freeform architecture, like circle patterns, ornamental patterns of planar panels, and optimized subconstructions.
