Hierarchical Modeling, Manipulation and Animation of Human Body

In this project we built a hierarchical model of a human body out of a set of unorganized polygons. Necessary information was inferred from the original data to define the relationship among body parts and enable user manipulation. Special efforts were made to ensure correct modeling and rendering of joints. Animation was achieved by recording a sequence of frames and replay them. Although this is basically a modeling project, we did our best to refine the rendering. We implemented a surface normal calculation algorithm proposed by H. Hoppe[2] and precalculated surface normal. Using this information, we did a smooth shading rendering.
