Abstract
A transform engine within a graphics pipeline is configured to rotate, or rotate and translate, one or more polygons in response to a screen orientation. The transform engine obtains a texture from a pre-rotated polygon and applies the texture to the rotated polygon. An image that reflects the rotated or rotated and translated polygon is then rendered in response to the screen orientation.
