Abstract
A pixel image at broadcast or graphics resolution is spatially transformed to represent the 2D projection of an image that has undergone movement in 3D space or is seen from a different viewer's position. For example, an image on a screen is delineated with four reference points designated by touching a pen on a tablet and then one is dragged with the pen along the screen to change the shape of the delineated image. At the same time, the entire delineated image is spatially transformed to make it continue to fill the entire changing shape and only that shape, until the dragged reference point is pinned to fix its position on the screen. Two or more designated point can be selected to move together as the pen drags them along the screen. The image being spatially transformed can be combined with a second image under the control of a stencil image to form a composite image.
