Improved Skeleton Computation of Extreme Vertices Encoded Volumes

Faster ASV Decomposition for Orthogonal Polyhedra, Using the Extreme Vertices Model (EVM)

The alternating sum of volumes (ASV) decomposition is a widely used technique for converting a b-rep into a CSG model, with all its implicit uses and advantages -like form feature recognition, among others. The obtained CSG tree has convex primitives at its leaf nodes, while the contents of its internal nodes alternate between the setunion and set-difference operators. This paper first shows th...

Solving Point and Plane vs. Orthogonal Polyhedra Using the Extreme Vertices Model (evm)

In a previous work, Orthogonal Polyhedra (OP) were proposed as geometric bounds in CSG. Primitives in the CSG model were approximated by their respective bounding boxes. The polyhedrical bound for the CSG object was obtained by applying the corresponding Boolean Algebra to those boxes. Also in that paper, a specific and very concise model for representing and handling OP was presented: the Extr...
