Hi, my name is Anthony Prior (better known as Tone) and I'm a PhD candidate at the School of Computer Science & Software Engineering at The University of Western Australia. My research is based on Haptic Virtual Sculpting. Outside of uni, I enjoy playing soccer, jogging, and spending time with friends.
My supervisors are Dr Karen Haines and Dr Amitava Datta.
I can be found in the W.A.S.P. area of the ground floor of the physics building, phoned on +61 8 6488 8147 or you can email me (do the obvious thing).
Virtual sculpting allows users to created 3-dimensional artworks and prototypes by using a 3D input device to control a sculpting tool. While existing methods allow a range of sculpting effects, they are limited to simplistic polyhedral tool shapes (usually spherical or point-based) or complex voxel-based tools that can only be applied at fixed orientations. My work is the development of a model for real-time voxel-based virtual sculpting that performs on-the-fly voxelization of a polyhedral tool to determine the region of the sculpture to modify. This allows the tool to take on a variety of shapes ranging from simple to complex polyhedra and also allows the tool to be applied to the sculpture at any orientation. The model provides 6-degrees-of-freedom haptic feedback allowing users to feel what they are sculpting. The scene is visualized using a localized Marching Cues algorithm. As an extension to this work, I am also developing a collaborative version of the sculpting model, allowing multiple users at remote locations to work on single sculpture simultaneously.
Below is a sample of some sculptures that have been produced by the sculpting application:
