Tessellation of a parameterized 3D modeled object

摘要

It is proposed a computer-implemented method for tessellating a three-dimensional modeled object parameterized for tessellation. The method comprises the steps of providing (S40) 2D meshes associated to geometrical data of a boundary representation of the modeled object, the boundary representation comprising the geometrical data including parametric surfaces and topological data including a set of faces each defined as a portion of the 2D domain of a respective parametric surface; and determining (S60) 3D meshes by evaluating the position of vertices of the 2D meshes on the respective parametric surfaces. Such a solution improves the tessellation of a 3D modeled object.
