Morphing techniques are employed to enable a user to locally deform a texture image on a three-dimensional object, and thereby align image features in a texture map with geometric features of the object. An affine transformation can be applied to the texture map to provide a rough fit of the texture image to the geometric model. The transformed texture image is placed on the geometric model and the user designates corresponding features on the texture image and the geometric model. Once the designations have been completed, the texture image is warped into a final, deformed image, which is then mapped onto the three-dimensional object. With this approach, the user can apply pre-existing images to three-dimensional models, without being required to repaint any portion of the image.
