ABSTRACT:
A method of deferring evaluation of a transform, in accordance with one embodiment of the present invention, includes buffering a plurality of vertex data. The method also includes receiving a draw command, accessing a given vertex data corresponding to the draw command and an associated transform indicator bit. The given vertex data is transformed if the associated indicator bit is cleared. After performing the transform, the vertex data is overwritten with the transformed vertex data and the associated transform indicator bit is set.
