Abstract
The present invention provides a method and apparatus for rendering an input video stream as a polygon texture. The method provides process steps to receive the input video data in a Mip Map generator, wherein the Mip Map generator converts the video data to Mip Map data and stores the Mip Map data in a first memory storage device; wherein the first memory storage device is located in a V buffer. The method further includes sending a data set from a Z buffer to V buffer and mapping the data set to RGB values at a texel address in the V buffer memory. The data set includes U, V and Z coordinates, Mip Map level and channel identification data. The V buffer includes a V buffer fetch module that receives the data set from the Z buffer and maps to RGB data within V buffer memory.
