  • Method for converting three-dimensional polygon data into quad edge data structure
    Patent number: 6489959
    Abstract: A method for converting OFF (object file format) from three-dimensional polygon data into a quad edge data structure which includes a step to determine if an input triangle of object file format is a whole new triangle, a step to find two edges and perform splice operation if the input triangle is a whole new triangle in the determination step, a step to find a quad edge from vertex link of quad edge data structure if the input triangle is not a whole new triangle in the determination step, and a step to find a candidate edge for a splice operation by comparing the link generated in the preprocessing stage and the vertex link of quad edge data structure and performing the splice operation on the candidate edge and the new quad edge.
