A GRAPHICS PROCESSING TECHNIQUE IN MECHANICAL PRODUCTS CAD

摘要

This article is to introduce a graphics processing technique that aims at employing computer to perform 2-D, 3-D part and assembly drawings of mechanical products. In 2D domain, three generating methods of graph are introduced and we propose loop operation. In 3-D domain, the theories and algorithm of the convex polygon's difference subdivision are put forward, 3-D part and assembly objects are operated in unified train of thoughts.
