Method and system for the generation of a computer model

摘要

A method of producing a control data set capable of controlling a machine tool comprising the steps of: (i) providing processing means capable of generating data and causing said processing means to generate a parametric surface indicative of the shape of an object; (ii) causing said processing means to generate a mesh indicative of a shape of a relief, said relief comprising height contours and said mesh having at least one edge; (iii) causing said processing means to perform one of the following: project said mesh onto said surface; wrap said mesh on to said surface; intersect said mesh with said surface, so as to preserve said height contours of said relief relative to one another; and (iv) causing said processing means to determine a trim boundary of the surface, said trim boundary having at least one edge, by performing one of the following: projecting said mesh into said surface; wrapping said mesh onto said surface; or intersecting said mesh with said surface, using said processing means such that said at least one edge of said mesh and said at least one edge of said trim boundary are contiguous.
