WebMar 3, 2024 · As design variables, we will use a free-form deformation approach. In this approach, a lattice of control points making up a bounding box are placed around the … WebThe free-form deformations are combined with an underlying coordinate transformation. The strategy is to use a coordinate transformation as follows. A coordinate transformation is given by (6.34) where 0 ≤ α ≤ 1 parameterizes a continuous family of these transformations that begins with identity, i.e., x = T(x, 0).

Free form deformation

WebFree-form deformation is a versatile modeling tool that can be used for solids, analytic surfaces or polygonal data. However with free-form deformations it can be difficult to control the shape of the object under complex deformations. WebThe generated mesh will be used later in process 4. In the pre-processing step, we also generate free-form deformation (FFD) points (process 3) that will be used later to morph the design surface. Refer to Geometric Parameterization. Then, we give a set of baseline design variables to the optimizer (process 2).
