Project: modeler and animator

• Create a hierarchical model: A hierarchical model is a way of grouping together shapes and attributes to form a complex object. Parts of the object are defined in relationship to each other as opposed to their position in some absolute coordinate system. Think of each object as a tree, with nodes decreasing in complexity as you move from root to leaf. Each node can be treated as a single object, so that when you modify a node you end up modifying all its children together. You will use OpenGL to implement a hierarchical model in this project.
• Finish several curve interpolation modules: The skeleton code currently only support linear interpolation, please extend it to support multiple curve types. You are required to implement Bezier and Catmull-Rom curves. The others are left as bonus.
• Animate your hierarchical model to make an aimation: Given the skeleton code and your own curve interpoltion modules, you now can use this curve-based animation system to animate your model and produce an animation.

• alt + select a group of points: selection
• shift + click on a control point : remove a control point
• right mouse button + drag : zoom in/out
• right mouse button + shift + drag : pan

We will have an in-class presentation to show your classmates your animation. Please also send me all your source codes and the resulted video. You can look at the following websites for inspiration on model and animtion.
