Abstract
A 3-dimensional wire frame representation is derived from a real 3-dimensional objects, where the surface of the object is generally featureless, by projecting a non-uniform pattern of randomly colored spots onto the 3-dimensional object and capturing images of the object by two cameras located at different positions. A wire frame representation of the object is then reconstructed from corresponding colored spots on the images captured by the two cameras. Wire frame representations are rapidly created using generic wire frames which are prototypical of a class of objects and which are modifiable to correspond to a specific instance of the class. A set of generic wire frames are bundled as a tool kit with software for editing wire frames. A method of morphing from a source 3-dimensional stereo rendered wire frame to a target rendered wire frame is also disclosed and the apparent camera viewpoint can change during morphing.
