Geometrically and physically based modeling for deformable objects simulating soft tissue interactions in surgery environments
Jörg Peters, Sukitti Punak · 2007
This dissertation contributes a method for modeling deformable objects that leverages computer graphics techniques and state-of-the-art hardware to simulate and visualize deformations, including topological transformations like cutting, in real time. The resulting models are suitable for interactive surgical simulation for illustration and teaching purposes. The approach has been tested, in particular, by modeling responsive fatty tissue. To support force feedback as well as visual feedback, the deformable object consists of three closely coupled representations for dynamic response, collision detection, and visualization. All three representations are implemented on the Graphics Processing Unit, rather than on the CPU, to leverage parallelism for speed.
