Deformable Solid Modeling using Sampled Medial Surfaces: A Multiscale Approach

We introduce a multiscale approach to modeling and rendering deformablesolid objects, replacing polygonal or spline-based B-repswith a medial representation (M-rep) based on hierarchically linked,discretely sampled medial figures. Each medial figure is a widthproportionallysampled medial surface which implies object boundarieswithin a width-proportional tolerance; boundary variationswithin this tolerance are specified separately by surface displacementsor texture-maps. M-reps share...
