1. An image transforming apparatus for transforming an input video signal representing a two-dimensional image into a transformed video signal representing a three-dimensional surface and for depicting illumination thereof, comprising:

  • means receiving data including said input video signal representing a two-dimensional image and light source position data for defining a shape of said three-dimensional surface based upon said input video signal representing a two-dimensional image and for providing a mapping data signal for transforming said input video signal representing a two-dimensional image into a signal representing said defined three-dimensional surface;

    means for transforming said input video signal representing a two-dimensional image in accordance with said mapping data signal so as to generate said signal representing said defined three-dimensional surface;

    controller means for producing a plurality of illumination pattern data signals based upon said signal representing said defined three-dimensional surface and said light source position data;

    generator means for receiving the plurality of illumination pattern data signals from said controller means for producing for generating a plurality of illumination pattern signals, each of which depicts differential illumination of said defined three-dimensional surface; and

    means for mixing said plurality of illumination pattern signals in accordance with said mapping data signal so that the mixing ratio of said plurality of illumination pattern signals is varied thereby.
