ABSTRACT:
A transform engine is configured to rotate, and/or rotate and translate, one or more polygons in response to screen orientation. Thus, when texture, obtained from a pre-rotated image is applied to a rotated polygon used to render such an image, a rotated version of such an image is generated in response to screen orientation. Alternatively, a user may select a rotation to re-orient an image to a screen view position.
