Abstract

The objective of this work is to model 3D objects in multiple-object scenes. Towards this objective, we employ deformable simplex meshes first developed by Delingette. These meshes have several convenient characteristics, including the fact that their deformation is controlled with simple geometric entities and is, therefore, computationally inexpensive. We begin with a cloud of 3D points that represents one or more object.s The cloud is then encapsulated with an initial simplex mesh to be subsequently deformed. During deformation, a breaking process enables the mesh to split into multiple meshes, one for each object. The breaking process is based on a 2D net approach introduced by Yoshino and laser refined by Bro-Nielsen. We model the arcs in the mesh as springs that break when their tension exceeds a threshold. This breaking process is additionally controlled by heuristics to prevent breaking on edges of the same object. Once the modeling process is complete, each object is separated from other objects and modeled with its own simplex mesh.
