Method, apparatus, and computer program product for geometric warps and deformations

A computer-implemented method for generating graphical warps or deformations through transformation of an undeformed model to a deformed model, said computer-implemented method comprising:

• receiving said undeformed model and a set of feature specifications each of said set of feature specifications comprising a source feature, a target feature, and related deformation parameters;
• receiving a set of transformations corresponding to said set of feature specifications and for mapping said source feature to said target feature in each of said set of feature specifications;
• receiving a set of strength fields corresponding to said set of feature specifications and defined over said undeformed model for scaling the magnitude of each of said set of transformations, establishing a set of scaled transformations;
• receiving a set of weighting fields corresponding to said set of feature specifications and defined over said undeformed model for determining the relative influence of said set of scaled transformations;
• computing a sum of said set of scaled transformations weighted by said set of weighting fields, for deforming said undeformed model to generate said deformed model;
• and
• returning said deformed model.
