Lossless compression of a 3D mesh including transforming of the mesh to a image

摘要

It is proposed a computer-implemented method for compressing a three-dimensional modeled object. The method comprises:- providing (S10) a mesh of the three-dimensional modeled object;- parameterizing (u,v) the mesh in a two-dimensional plane, the parameterization of the mesh resulting in a set of vertices having two-dimensional coordinates;- providing a grid on the two-dimensional plane; and- modifying the two-dimensional coordinates of each vertex by assigning one vertex to one intersection of the grid.;Such compression method is lossless, completely reversible, suitable to efficiently reduce the storage size of a CAD file.
