Handling complexity is one of the key problems of computer graphics. Current applications of computer graphics, ranging from games to computer aided design, often have to handle highly complex three dimensional models. Usually, multi-resolution algorithms and data structures are employed for efficient processing: A model is represented at different levels-of-detail in order to adapt the representation accuracy to processing demands. A recent approach is the usage of point-based multi-resolution data structures: A geometric model is approximated by a hierarchy of sample points of different resolution. As being generally applicable and easy to use, such representations have recently gained some interest.

The talk will discuss different data structures for point-based multi-resolution representations. The data structures are employed for different rendering applications and their efficiency for these tasks will be discussed. Overall, the talk should demonstrate that point-based multi-resolution techniques can be employed to solve rendering problems that often have been hard to handle using former techniques.
