A Real-time 3D Virtual Sculpting Tool Based on Modified Marching Cubes
Kuo-Luen Perng, Wei-Teh Wang, Mary Flanagan, Ming Ouhyoung · 2001
We present a real-time interactive modeling system for users to create sculpture in a virtual world. This system uses voxels as the smallest editable unit, and uses a 3D tracker system to simulate virtual sculpting tools. A modified Marching Cubes is proposed for cutting edge anti-aliasing, and we apply octree and boundary division to accelerate the system and reduce the memory usage up to 20 times. Users can create virtual sculpture art pieces or 3D prototyping models easily through the intuitive user interface and immersing display device such as a HMD or a Vision Station. This system can run on a PC (PIII-500) supplied with any texture and lighting accelerated 3D graphics card in real-time. Fig.1 shows some of the models made by our system.
