Abstract
A method and apparatus for providing a three-dimensional object on live video includes processing that begins by filling at least a portion of a back butler with a key color, where the key color indicates the presentation of the video. The processing then continues by writing the three-dimensional object into the back buffer. Note that by providing the key color into the back buffer as a clearing operation or having a back most Z value, when the three-dimensional object is written into the back buffer, it will be in a foreground viewing perspective with respect to the live video. The processing then continues by flipping the back buffer to become a primary surface such that the data stored in the primary surface is subsequently displayed on a display device.
