Segmentierungsergebnis zu erhalten. A difficulty of voxel-based sculpturing and modeling is the limitation of the design space by the fixed boundaries of the voxel volume. We present the concept of an infinite voxelized virtual modeling space. A finite shape located in the virtual modeling space is embedded in a voxel window which is enlarged if required by the spatial development of the shape. In order to cope with highly resolved or large shapes, the voxel windows are stored in a virtual voxel memory which implements a paging mechanism to secondary memory.
Visualization is performed by meshes obtained by the marching cubes algorithm.
Because highly resolved or large shapes may cause a considerable number of triangles, an adaptive meshing approach based on a filtered hierarchy of voxel volumes is presented. The surface mesh is represented in a so-called surface octree which allows for fast rendering by the Performer library. Es wird das Konzept eines unendlichen gevoxelten virtuellen Modellierraums vorgestellt. A computer-based system is presented that is able to employ arm gestures to control a multimedial presentation. The modeling of presentations is realized based upon an abstract presentation paradigm.
