摘要：

In this paper, a volume parametric model is computed from a piecewise smooth skeleton. Generating a volume model from a stick figure S defined in 3D is an intuitive process: given S whose topology is a pseudo-graph and whose edges are embedded as Bezier curves in R-3, we propose a method for creating a thick volume parametric model "around" S. The volume model we generate is based on semi-simploidal sets, which guarantees a proper topology and provides a 3D parametric domain for Bezier spaces. This volume is a continuous piecewise Bezier representation which boundary corresponds to a B-Rep made of tensor product Bezier patches. (C) 2021 Elsevier B.V. All rights reserved.
