RBF (original_control_points=None, deformed_control_points=None, func='thin_plate_spline', radius=1, smoothing=None, extra_parameter=None)
Class that handles the Radial Basis Functions interpolation on the mesh points
| Type | Default | Details | |
|---|---|---|---|
| original_control_points | NoneType | None | (n_control_points, 3) array with the coordinates of the original interpolation control points before the deformation. Default is the vertices of the unit cube. |
| deformed_control_points | NoneType | None | (n_control_points, 3) array with the coordinates of the interpolation control points after the deformation. Default is the vertices of the unit cube. |
| func | str | thin_plate_spline | MODIFIED: DEFAULT is thin plate spline. Several basis function are already implemented and they are available through the ~pygem.rbf.RBF by passing the name of the right function. |
| radius | int | 1 | Scaling parameter that affects the shape of the basis functions. |
| smoothing | NoneType | None | MODIFIED: added parameter. IF defined, a constant values will be added on the diagonal of the matrix Dcc. s |
| extra_parameter | NoneType | None |
