    摘要： A method, apparatus and article of manufacture are provided for handling both scalar and vector components during graphics processing. To accomplish this, vertex data is received in the form of vectors after which vector operations are performed on the vector vertex data. Next, scalar operations may be executed on an output of the vector operations, thereby rendering vertex data in the form of scalars. Such scalar vertex data may then be converted to vector vertex data for performing vector operations thereon.

    摘要： A system, method and computer program product are provided for a hardware implementation of a blending of “skinning,” during graphics processing in a graphics pipeline. During processing in the pipeline, a plurality of matrices and a plurality of weight values are received. Also received is vertex data to be processed. A sum of a plurality of products may then be calculated by the multiplication of the vertex data, one of the matrices, and at least of the weights. Such sum of products is then outputted for additional processing.

    摘要： A system, method and article of manufacture are provided for programmable processing in a computer graphics pipeline. Initially, data is received from a source buffer. Thereafter, programmable operations are performed on the data in order to generate output. The operations are programmable in that a user may utilize instructions from a predetermined instruction set for generating the same. Such output is stored in a register. During operation, the output stored in the register is used in performing the programmable operations on the data.

    摘要： A method, apparatus and article of manufacture are provided for a transform system for graphics processing as a computer system or on a single integrated circuit. Included is an input buffer adapted for being coupled to a vertex attribute buffer for receiving vertex data therefrom. A multiplication logic unit has a first input coupled to an output of the input buffer. Also provided is an arithmetic logic unit having a first input coupled to an output of the multiplication logic unit. Coupled to an output of the arithmetic logic unit is an input of a register unit. An inverse logic unit is provided including an input coupled to the output of the arithmetic logic unit or the register unit for performing an inverse or an inverse square root operation. Further included is a conversion module coupled between an output of the inverse logic unit and a second input of the multiplication logic unit. In use, the conversion module serves to convert scalar vertex data to vector vertex data. Memory is coupled to the multiplication logic unit and the arithmetic logic unit. The memory has stored therein a plurality of constants and variables for being used in conjunction with the input buffer, the multiplication logic unit, the arithmetic logic unit, the register unit, the inverse logic unit, and the conversion module for processing the vertex data. Finally, an output converter is coupled to the output of the arithmetic logic unit for being coupled to a lighting module to output the processed vertex data thereto.

    摘要： A method, apparatus and article of manufacture are provided for sequencing graphics processing in a transform or lighting operation. A plurality of mode bits are first received which are indicative of the status of a plurality of modes of process operations. A plurality of addresses are then identified in memory based on the mode bits. Such addresses are then accessed in the memory for retrieving code segments which each are adapted to carry out the process operations in accordance with the status of the modes. The code segments are subsequently executed within a transform or lighting module for processing vertex data.
