METHOD FOR DISPLAYING SECTION VIEWS OF A 3D MODEL USING A FRAGMENT SHADER

摘要

The present invention relates to a method for interactively displaying section views of a 3D model (10), characterized in that it comprises the following steps: ·Performing a projection of said 3D model (10); ·Using a table (20) having two dimensions comprising components of said projected 3D model (10), determining if each entry in said table (20) is modified or not by comparing the 3D coordinates of a point (30) corresponding to the entry before projection with an oriented section surface (40) and by defining if said point (30) is in front of or behind said oriented section surface (40); and ·Drawing said point (30) if said point (30) is behind said oriented section surface (40).
