| Abstract: | Three dimensional imaging of medical objects from volume data is considered increasingly useful in various fields, such as medical diagnosis, forensic medicine, palaeoanthropology etc.Marching Cubes algorithm, as one of the advanced surface based rendering algorithms,is analyzed.The algorithm is improved in several aspects, including solution in several ambiguous cases and shortage of memory, reduction of the computing cost.An advanced 3D medical volume data rendering prototype system is provided, which is based on SGI Indigo2 Open GL platform and consists of a powerful display engine and has satisfying solution. |
