Enhancements in Blending Algorithms
This article describes a rounding operation for a 3D CAD boundary representation (B-Rep) solid model. Complex combinations of convex and concave edges are handled predictably and reliably. At vertices the surfaces are smoothly connected by one or more surface patches. An algorithm for the creation of blending surfaces and their integration into the model is outlined. The sequence of topological modifications applied to the solid model is illustrated by examples including some special case handling.
