dc.description.abstract This research work focused on real time manipulation of 3D volumetric data which involved implementing graphic rendering and haptic rendering techniques that allow simulation of the interaction between di erent shapes of cutting tools and a 3D model. This work accommodates the interaction between any arbitrary 3D volumetric mod- els and di erent shapes of tools that include capsule, cylinder, cone and sphere. As an application, a virtual reality based dental surgery simulation system that exploits haptic interaction was developed in which 3D grid data representation of volumetric tooth model was used in haptic rendering. Collision Detection between 3D volumetric virtual tooth model and di erent shapes of virtual dental tools mentioned above is handled using volumetric sampling and occupancy map techniques. The force models for di erent shapes of virtual dental tools to compute the force responses based on the interaction with volumetric tooth data are implemented. Force response magnitude was based on the internal structures (di erent densities means di erent sti ness) of volumetric tooth model and number of collided volumetric sample points of tools. The main functionalities of the system are the simulation of dental surgical procedures such as probing and cutting on the volumetric virtual tooth model. The graphic rendering of tooth model and real time manipulation of volumetric tooth model using di er- ent shapes tool are implemented realistically and e ciently using PolyVox technology which internally uses Marching Cube algorithm for surface reconstruction. The sim- ulation system is mainly developed using C++ OpenGL programming languages in Microsoft Visual Studio 2005 in the windows platform. Finally a formal evaluation of the simulation carried out by dentists to verify the realistic feel of the surgical proce- dures on volumetric virtual tooth. The evaluation results suggested that the overall function of the simulator is very close to realistic. en_US
