Generation of swept volumes of toroidal endmills in five-axis motion using space curves
Accurate prediction of the swept volume of a cutting tool is essential in NC verification algorithms for detecting deficiencies in a proposed tool path, such as gouging, undercutt...

Matchmaker: manifold BReps for non-manifold r-sets
Many solid modeling construction techniques produce non-manifold r-sets (solids). With each non-manifold model N we can associate a family of manifold solid models that are infini...

A novel FEM-based dynamic framework for subdivision surfaces
Subdivision surfaces have been extensively used to model smooth shapes of arbitrary topology. Recursive subdivision on an userdefined initial control mesh generates a visually pl...

Fast volume-preserving free form deformation using multi-level optimization
We present an efficient algorithm for preserving the total volume of a solids undergoing free-form deformation using discrete level-of-detail representations. Given the boundary r...

Resolving non-uniqueness in design feature histories
Nearly all major commercial computer-aided design systems have adopted a feature-based design approach to solid modeling. Models are created via a sequence of operations which app...

Optimal Analysis-Aware Parameterization of Computational Domain in Isogeometric Analysis
Abstract. In isogeometric analysis (IGA for short) framework, computational domain is exactly described using the same representation as that employed in the CAD process. For a CAD...

Distance Computation between Non-Convex Polyhedra at Short Range Based on Discrete Voronoi Regions
An algorithm for calculating the minimum distance between non-convex polyhedra is described. A polyhedron is represented by a set of triangles. In calculating the distance between...
