Compression of a three-dimensional modeled object
First Claim
1. A computer-implemented method for compressing a three-dimensional modeled object, comprising:
- providing a mesh of a three-dimensional modeled object;
parameterizing (u,v) the mesh on a two-dimensional plane;
converting the parameterized mesh into an image I;
defining a grid of cells from the image I, each cell being defined by a set of control points;
computing a relevance of each cell of the grid;
determining at least one cell having a relevance lower than a pre-determined threshold;
resizing the at least one determined cell and computing a resulting grid;
computing a transformation for each pixel of the image from the resulting grid; and
applying the computed transformation to the image I.

Abstract
The invention notably relates to a computer-implemented method for compressing a three-dimensional modeled object. The method comprises providing a mesh of a three-dimensional modeled object, parameterizing (u,v) the mesh on a two-dimensional plane, converting the parameterized mesh into an image I, defining a grid of cells from the image I, each cell being defined by a set of control points, computing a relevance of each cell of the grid, determining at least one cell having a relevance lower than a pre-determined threshold, resizing the at least one determined cell and computing a resulting grid, computing a transformation for each pixel of the image from the resulting grid, and applying the computed transformation to the image I.
