摘要： A fully programmable graphics processing engine is provided. The graphics processing engine includes three independent, programmable processors that run independent sets of instructions from independent instruction storage facilities. Graphics processing tasks may be distributed among the serially pipelined processors to allow for load balancing and parallel processing. The graphics processing engine may be a graphics co-processing core within a larger, general purpose computing system. Register files and storage units may be addressable by the system host processor. Each processor accepts incoming data for state or context updates. Each processor may execute a specific graphics processing function by executing a set of instructions when a predetermined memory address is accessed.

摘要： A volume of data, acquired from devices that output three dimensional data, is parsed into smaller subvolumes, or digital data segments, and each digital data segment is rendered allowing application of the original data without modifying or scaling the three dimensional volume of raw data. If measurements of the whole volume of data received by texture mapping hardware is not completely parsable into pre-defined digital data segments, dimensions of any irregular digital data segment are adjusted to overlap an adjoining segment to allow rendering of adjusted, irregular digital data segments as if they were pre-defined digital data segments. The adjusted texture coordinates are utilized to determine the point where the texture mapping engine begins texturing and to determine the percentage of overlap of the adjusted irregular digital data segment with the adjoining pre-defined digital data segment. This calculation accounts for overlap and allows application of digital data segments whose dimensions are not parsable into pre-defined digital data segments, or subvolumes.
