Coquillart International Conference on Computer Graphics and… 1990 Corpus ID: 15281383 In computer graphics, free-form deformation (FFD) is a geometric technique used to model simple deformations of rigid objects. It is based on the idea of enclosing an object within a cube or another hull object, and transforming the object within the hull as the hull is deformed. Deformation of the hull is based on the concept of so-called hyper-patches, which are three-dimensional analogs of parametric curves such as Bézier curves, B-splines, or NURBs. The technique was first describe…

Free-form deformation - Wikipedia

WebA deformation is called an affine deformation if it can be described by an affine transformation. Such a transformation is composed of a linear transformation (such as rotation, shear, extension and compression) and a rigid body translation. Affine deformations are also called homogeneous deformations. [8] WebIntroduction. Free Form Deformation (FFD) is part of the computer graphics literature on soft objects. The definition of a soft object is an object that can be deformed by the user or during the process of animation. Soft object deformation is used for many purposes: Shape distortion to highlight dynamic interaction with the environment. WebNon-Rigid Registration: Free Form Deformation.
