Abstract
This paper describes the development of a free-form deformation model (FFD) which is an extension of the Scodef model of geometric constraint-based deformations. The deformation is applied to a point over the surface and it is restricted to a region which is limited by a closed B-Spline curve acting as a profile. The main difference from the original model is that in the new one, the conditions to define restrictions with non rectilinear trajectories have been established. These conditions are represented by 4D B-Spline curves. With the proposed solution, the deformed surface is adjusted precisely as described by both B-Spline curves. The model has been called N-Scodef.
