Patent number: 6556199Abstract: The present invention relates to an apparatus and method for voxelizing geometric and volumetric models of objects in 3D space, i.e. converting these 3D models into a voxel-based volume representation. Based on an unconventional way of using the 3D graphics hardware in modern graphics workstations, the present invention generates slices of the model as frame buffer images, and then stores the slices in a 3D texture memory for interactive volume rendering. Since most of the computation is carried out directly by hardware, the voxelization algorithms of the present invention are much faster than existing algorithms, and are able to achieve interactive volume rendering and manipulation of complex 3D scenes consisting of intermixed geometric models and sampled volume data sets (e.g. CT and MRI scans).Type: GrantFiled: August 11, 1999Date of Patent: April 29, 2003Assignee: Advanced Research and Technology InstituteInventors: Shiaofen Fang, Hongsheng Chen
