Interactive freeform solid modeling with haptic interface

Abstract

"This dissertation presents the development of a Virtual Sculpting system and addresses the issues of interactive solid modeling with haptic interface. A virtual reality (VR) approach is taken to make the use of modeling tools more intuitive and interactive. The virtual sculpting method is based on the metaphor of carving a solid block into a 3D freeform object. The VT interface includes stereo viewing and force feedback. The geometric modeling is based on the Sweep Differential Equation method to compute the boundary of the tool swept volume, and based on the ray-casting method to perform Boolean operations between the tool swept volume and the virtual stock in dexel data to simulate the sculpting process. A new method for surface reconstruction from dexel data is presented"--Abstract, page iii.
