ABSTRACT:
An image processor adapted to perform a volume rendering operation from voxel data by a depth queuing method, comprising a three-dimensional memory for storing the voxel data therein, a plurality of three-dimensional address generators for generating addresses to read out the data from the three-dimensional memory, and a plurality of pixel calculators for processing the read-out data from the three-dimensional memory by the depth queuing method. The memory consists of a fast accessible one such as a static RAM. The required calculation time can be shortened to expedite the volume rendering operation, and a high-speed process is achieved due to the use of such a fast accessible memory.
