Then, a short description of the creation and rendering generally to surface-based representations is also given. 1 Polygonal Mesh Representations Polygonal meshes are the most popular and common representations for 3D objects in computer graphics. The representation is also the fundamental primitive for graphics hardware pipeline techniques. The main advantage is that the representation can represent any object with almost no topological restrictions. The representation can be adjusted according to the requirement of realism and better approximation.
Thus, physically-based techniques basically construct the rules which can be physical rules or behavioral rules and then follow the rules to update the behavior of the objects in the scene. However, these techniques are computationally expensive, since the simulations involve numerical computation including integration, solving the partial differential equations, and so on. Thus, the physically-based techniques are generally offline. All three methods mentioned are first designed for offline animation.
This has the benefit that changes in shape, but not topology, can be dynamically updated by simply resending the vertex data without updating the face connectivity. 5 shows the face-vertex mesh of a cube. However, the downside is that the edge information is still implicit, that is, a search through all surrounding faces of a given face is still needed, and other dynamic operations such as splitting or merging a face are also difficult. 3. Corner-table meshes The representation stores a set of vertices in a predefined table.
