ABSTRACT:
A system and method for deforming objects uses delta free-form deformations (DFFD). The DFFD computes a delta vector based on a conventional free-form deformation (FFD) and an original vertex. Multiple delta vectors can be computed and combined for each vertex. Because delta vectors are independent from each other, various operations such as rotations and translations in addition to multiple overlapping deformations are applied to the vertex with superior results over the conventional FFD.
