WebSep 1, 2006 · A new method of free-form deformation, t-FFD, which works on a simple mapping mechanism, where each point of the original shape is parametrized by the local coordinate system on each triangle of the control mesh. Expand. 68. Save. Alert. A new free-form deformation through the control of parametric surfaces. 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…

WebWe use the Free-form deformation (FFD) technique, popularized by Tom Sederberg in the world of computer-aided graphic design, as our parametrization method. The FFD is a mapping of a region in 2D or 3D that is bounded by a set of B-splines. Every point with the region is mapped to a new location based on the deformation of the bounding B-spline ... cchs powerschoolWeb自由变形技术 Free-Form Deformation 是编辑几何模型的重要手段，它于 80 年代由 Siedberg 等人提出，目前许多三维建模软件中都有这种变形算法。 自由变形方法在变形 … cchs powerchart loginWeb1.Create an initial FFD box with volumetric control points (aka.
