ABSTRACT:
A mathematical computation circuit to interpolate attribute values along a line between two points where the attributes are known and a video circuit using the interpolation circuit. The interpolation circuit includes a circuit to calculate the rate of change of said attribute between said two points on a raster-scanned display on a per scan line basis and a circuit to add the rate of change of said attribute per scan line to the current attribute value for the current scan line as each new scan line occurs. The sum is used as the new current value. A video system uses multiple instances of this interpolation circuit and includes a sorter to sort vertices records from a display list and send the appropriate attribute data to the interpolation circuits. There rates of change are calculated and attribute values developed for each pixel location. A video control circuit then generates color, saturation and intensity data for use in filling a frame buffer in accordance with addresses generated by an address generation circuit. The frame buffer is then read to generate the display.
