OpenCASCADE Rational Bezier Curves eryar@163.com Abstract. Although polynomials offer many advantages, there exist a number of important curve and surface types which cannot be represented precisely using polynomials, e.g., circles, ellipses, hyperbo…

Mesh Algorithm in OpenCascade eryar@163.com Abstract. Rendering a generic surface is a two steps process: first, computing the points that will form the mesh of the surface and then, send this mesh to 3D API. Use the Triangle to triangulate the param…
