Interactive Manipulation of Voxel Volumes with Free-formed Voxel Tools
نویسندگان
چکیده
Manipulation of high-precision voxel volume at interactive speed is still not immediately possible by known algorithms on today’s workstation hardware. We propose to decompose a voxel-based modeling system into layers. The concept opens the possibility to apply less precise but fast algorithms of manipulation and rendering, but also to produce voxelmodels at the higher precision possibly required by the application. With this concept in the background, we present a fast, though slightly imprecise algorithm for the problem of updating a voxel workpiece touched by a voxel tool interactively moved by the user along a path with six degrees of freedom. On an SGI Octane MXE, interactive speed is achieved for workpieces up to voxels and tools up to voxels.

Development of a free anthropomorphic voxel model of human body for wide-band computational electromagnetics dosimetry
To calculate and evaluate wave scattering and penetration of electromagnetic waves in different biological tissues it is necessary to use a realistic model of the human body, with all tissues resolved and separately assigned with appropriate electric/magnetic properties. We report the development of a realistic 3D whole-body human model that has been adapted for simulation in CST software, cont...

Interactive sculpting is the process by which a designer can impose free-form shape changes on the object being designed. It has potential applications in the fields like computer aided geometric design arid rapid prototyping. Our approach to interactive sculpting is through the intermediate step of interactive virtual nlachining (IVM). IVM is a subset of interactive sculpting in that the degre...
