    A new SIMD parallel algorithm to extract a Boundary representation from Classical Octrees is presented. The algorithm makes use of a Geometrically Deformed Model (GDM) to smooth an initial naive polygonization. The GDM ...

    The union of axis-aligned boxes results in a constrained structure that is advantageous for solving certain geometrical problems. A widely used scheme for solid modelling systems is the boundary representation (Brep). We ...
