Abstract
The use of computer animation is very common now, but authoring tools for making these works also increase their complexity to bring in new technologies. 3D computer animation is more difficult because of the complexity of it. So, the user must spend much time to be familiar the tool, and spend much time to edit the computer animation. There are many commercial tools now, but they are very hard to learn because of its complexity. Though as to professional user, the complicated operation is essential. , but as to just non-professional user, these too much operation will let them fear to retreat instead. So we think that it is essential that one user-interface for the non-professional user to user.
One of the general solutions for driving the motion of a 3D object is by constructing a skeleton and defining the binding relationship and then adjusting the key-pose of it. skeleton-driven deformation is the one of the common method to drive the deformation of the 3D model, but the generation of the skeleton is hard and time-consuming.
Based on the demand of above demands, we introduce an institute 3D animation edit interface. Our system can generate the skeleton of the model and generate the relationship between the skeleton and the surface of the model automatically. We adopted a sketch based input method for accelerating the learning and the editing process. We can easily generate an interesting computer animation by set some key frames by our interface. Because of the artifacts during deformation, some optimization such as smoothing is used, and we used displacement map to preserve the detail of the model. We also can manipulate the structure of the skeleton to fit the model better. This process will make the editing more institute and more interesting , it also can user more triangles to preserve the detail when doing some deformation.
As a result, our system provides user a institute interface, which is easy to learn and to do some animation. Non-professional also can be familiar to the system in few minutes, and create simple but interesting animations also in few minutes.
