### 1. Rapid Rendering of Massive Models

Research with CAD software on developing algorithms to render massive models using current graphics cards. The algorithm accelarates the rendering of such models. Models used for research include the complex systems of a submarine.

### 2. Interactive and Exact Collision-Detection Systems.

Research develops efficient algorithms for collision detection between polygonal and curved models.

### 3. 3D Polyhedral Morphin Using Feature-Based Surface Decomposition.

Used for computer animation, modeling and shape recognition, morphin computes the transformation which changes one object into another. The algorithm presented computes the morphing necessary for corresponding pairs of surface patches.

### 4. OBBTree

### 5. Metamorphosis of the Cube.

Research asks the following questions:
a.) Can you unfold a complex polyhedron into a simple polygon?
b.) Can you fold a simple polygon into a complex polyhedron?
