Reconstruction of feature volumes and feature suppression
Sashikumar Venkataraman, Milind Sohoni · 2002
This paper describes a systematic algorithm for reconstructing the feature volume from a set of faces in a solid model. This algorithm serves a dual purpose. Firstly, the algorithm generates the feature volume by extending or contracting the neighboring faces of the set of faces. Secondly, the algorithm may also be used to remove (or suppress) the face-set from the model. The algorithm uses a divide-and-conquer strategy and geometric cues to identify the correct topology. It robustly handles a wide class of feature volumes with complex topology and geometry. A simplified version of the algorithm has also been presented to handle volumes resulting from 2.5D features.
