Arbitrary shaped deformations with DOGME
In the field of 3D computer design, free-form deformations, also known as FFD, play an important role. There are mainly two trends in FFD: with a lattice or using constraints. The present paper is based upon the latter family of FFDs, and more specifically the deformation model DOGME. We will present a way of using curvilinear constraints, with either a point or a curve as the constrained element. We will also present two means of using the volume defined by an arbitrary closed polyhedral mesh as the volume of influence around the constraints.
