摘要
A volumetric data organization method for volume rendering that is both cache efficient and efficient for hardware graphics design and utilization. A volume data set is divided up into a number of smaller sub- volumes or blocks through a process called blocking. The size of each sub- volume is a function of the computer system being used and/or the application program being run. Typical sub-volume sizes are approximately 5% of cache size. Each voxel tuple in a volume data set is converted to a linear address for linear storage in memory. Two techniques are used for blocking: overlapping and non-overlapping. The non-overlapping blocking technique divides the volume data set up into sub-volumes such that each sub-volume contains a unique set of voxels with no overlap of voxels between sub-volumes. The overlapping blocking technique expands each sub- volume to include voxels located on six planes that are located one voxel away from the sub-volume's existing bounding planes. After employing either technique, each sub-volume can be selected as containing desired or non-desired data. The volume rendering system ignores any sub-volumes that do not contain desired data, greatly speeding up rendering time.
