摘要： An image processing system for producing an image from three-dimensional image data. The system uses a command generator to generate one or more plotting commands for producing the image, and features a coordinate calculator for transforming the three-dimensional data into two-dimensional data. The coordinate calculator operates as a coprocessor of the command generator, and as such does not require use of the system bus to perform its functions.

摘要： The present invention relates to the architecture and use of a computer system optimized for the efficient modeling of graphics. The computer system has a primary processor and a graphics processor. The primary processor has two vector processor units within it, one which is closely connected to central processor unit. Simultaneously performing complex modeling calculations on the first vector processor and CPU, and geometry transformation calculations on the second vector processor, allows for efficient modeling of graphics. Furthermore, the graphics processor is optimized to rapidly switch between data flow from the two vector processors. In addition, the graphics processor is able to render many pixels simultaneously, and has a local memory on the graphics processor chip that acts as a frame buffer, texture buffer, and z buffer. This allows a high fill rate to the frame buffer.

摘要： A data format is provided capable of assigning a desired color lookup table (CLUT) to a texture pattern of each polygon drawn on a two-dimensional display screen. Assuming that TPF represents a pixel depth of the texture pattern, when TPF is 00, 01, and 10, the format (CLUT) is applied of a 4-bit mode, an 8-bit mode, and 16-bit mode respectively, whereby its related command is decreased in word length and thus requires less storage in a source video memory.

摘要： A method and apparatus for generating images wherein access to a main memory is minimized during a translation of an image of a 3D object or the like on a display screen to increase the speed of the translation process. A string of draw commands for drawing an image is preceded by an offset draw command which indicates offset values for the coordinates of the vertices of the image, and the image is translated on the display screen in accordance with the offset draw command. A header portion of each of the offset draw command and the draw commands that constitute the draw command string includes data indicating the address on the main memory of the next draw command to be executed. The image generation apparatus includes a frame buffer in which an image is drawn, a CPU for generating a string of draw commands to draw the image and an offset draw command indicating offset values for the coordinates of the vertices of the image, a main memory for storing the string of draw commands and offset draw command generated by the CPU, and a drawing device portion for executing the string of draw commands and offset draw command from the main memory to draw a translated image on the frame buffer.

摘要： Apparatus and method which map a texture image onto a polygonal area in which the mapped image can have a dynamic brightness range greater than the dynamic brightness range of the original texture image. The brightness levels of the pixels of the texture image are ascertained and reduced, and the polygonal area onto which the texture image is mapped is shaded by multiplying the reduced brightness levels of the pixels by a shading factor, wherein a shading factor greater than 1 produces a mapped texture image which has a dynamic brightness range that is greater than the dynamic brightness range of the texture image.
