Program design and its application for drawing ternary phase diagram;

Research of silhouette in pen-based 3D sketch rendering;

This paper analyzed technology and detection algorithm of 3D model silhouette, and proposed a new 3D model silhouette detection algorithm, then designed and implemented a 3D sketch rendering system with the algorithm, where user can interact with the 3D models freely and flexibly in the 2D environment.
