THREE-DIMENSIONAL IMAGE COMPOSITING ON A GPU UTILIZING MULTIPLE TRANSFORMATIONS

A method includes performing a first transform operation with respect to an image element to transform the image element from an object space, defined by an object coordinate system, to an intermediate space defined by an intermediate coordinate system. A first computational operation is performed with respect to the image element in the intermediate space. A second transform operation is performed with respect to the image element to transform the image element from the intermediate space to a world space, defined by a world coordinate system. A second computational operation is performed with respect to the image element in the world space.
