ABSTRACT:
A computer controlled animation projection system is described. The system permits the projection of animated images onto a three dimensional projection surface, whether or not the surface is originally designed as a projection surface. The system comprises an animation source that can be edited using a processing means, a projection means, and an interface for coupling the animation source to the projection means. In operation of the present invention, a projection surface is selected, and an animation sequence is projected onto the projection surface. Portions of the projection surface upon which no image is to be projected are identified. Using a paint program, the background or projected frame is edited to "black out" those regions of the projected image that are projected onto those identified portions. This is done while the image is still being projected, so that the changes are viewed as they are made. The regions of the projected image corresponding to the identified portions of the projection surface are colored black (no light) so that no light is projected onto those identified portions. This is done to allow "blending" of the projected image into the projected surface, reducing artifacts and boundaries that reveal the presence of a projected image.
