 surface trimming
 The proposed algorithm is suitable for interactive operations of surface trimming. In existing methods of surface trimming, cutting lines are usually picked manually or assumed to be known or determined by computing the intersection between two surfaces. Surface trimming is widely used in surface modeling, texture mapping and medical simulation.
