摘要

A NEW METHOD AS A POST-PROCESSING STEP IS PRESENTED TO IMPROVE THE SHAPE QUALITY OF TRIANGULAR MESHES, WHICH USES A TOPOLOGICAL CLEAN UP PROCEDURE AND DISCRETE SMOOTHING INTERPOLATE (DSI) ALGORITHM TOGETHER. THIS METHOD CAN IMPROVE THE ANGLE DISTRIBUTION OF MESH ELEMENT. WHILE KEEPING THE RESULTING MESHES CONFORM TO THE PREDEFINED CONSTRAINTS WHICH ARE INPUTTED AS A PSLG.
