Rapid processing of three-dimensional graphical objects from tomographic data |
摘要 |
Three-dimensional objects within a tomographic data-base are extracted for viewing by comparing the tomographic data to a predetermined threshold or range defining the object boundaries. A surface extraction method is structured so as to allow for several vector operations, thus adapting the method for implementation using an array processor.
