Abstract

Morphing is performed without self-intersection in a vector space, for the outlines for various types and shapes of figures. The morphing is performed by apparatus containing an outline extractor, for receiving two target figures for the morphing process and for extracting a set of outlines for each of the target figures; an outline tree generator and an outline tree arrangement unit, for retaining one specific outline of each of the two sets of outlines and for deleting the other outlines; an outline editor, for performing a smoothing process for the two outlines for the target figures that are retained by the outline tree arrangement unit in order to prevent self-intersection during the morphing process; and a sequence generator and a morphing viewer, for performing the morphing process in response to the progress made by the smoothing process performed by the smoothing processor.
