Functions for computing and applying basis function transforms. More...
Functions | |
| WlzBasisFnTransform * | WlzMakeBasisFnTransform (WlzErrorNum *dstErr) |
| Makes a new basis function transform. The transform will be returned with a NULL basis function pointer which needs to be set along with all the other fields of the transform structure. More... | |
| WlzErrorNum | WlzBasisFnFreeTransform (WlzBasisFnTransform *basisTr) |
| Free's the given basis function transform. More... | |
| WlzBasisFnTransform * | WlzBasisFnTrFromCPts2D (WlzFnType type, int order, int nDPts, WlzDVertex2 *dPts, int nSPts, WlzDVertex2 *sPts, WlzCMesh2D *mesh, WlzErrorNum *dstErr) |
| Creates a new basis function transform of the given type, which will transform an object with the given source verticies into an object with the given destination verticies. See WlzBasisFnTrFromCPts2DParam(). More... | |
| WlzBasisFnTransform * | WlzBasisFnTrFromCPts2DParam (WlzFnType type, int order, int nDPts, WlzDVertex2 *dPts, int nSPts, WlzDVertex2 *sPts, WlzCMesh2D *mesh, int nParam, double *param, WlzErrorNum *dstErr) |
| Creates a new basis function transform of the given type, which will transform an object with the given source verticies into an object with the given destination verticies. If a constraining object is given all distances will be computed within the given object for those basis functions which support constrained evaluation (Gauss, multi-quadric and thin-plate spline). Additional basis functions parameters may be supplied via the nParam and param parameters. Currently this is only used to supply the multi-quadric delta or gauss parameter scaling. The default values of multi-quadric delta = 0.001 and gauss param = 0.9 are used if nParam <= 0 or param == NULL. More... | |
| WlzBasisFnTransform * | WlzBasisFnTrFromCPts3DParam (WlzFnType type, int order, int nDPts, WlzDVertex3 *dPts, int nSPts, WlzDVertex3 *sPts, WlzCMesh3D *mesh, int nParam, double *param, WlzErrorNum *dstErr) |

| WlzErrorNum | WlzBasisFnTPS2DChangeCPts (WlzBasisFnTransform *basisTr, int nDPts, WlzDVertex2 *dPts, int nSPts, WlzDVertex2 *sPts, WlzObject *cObj) |
| Changes control points in an existing basis function transform. Using this function to add, move or delete control points avoids recomputing distance transforms when using basis functions which use constrained distances. Because distances transforms are very expensive to compute calling this function can be far more efficient, but when non-constrained (Euclidean) distances are used then there is no benefit in using this function as opposed to WlzBasisFnTPS2DFromCPts(). The full list of control points must be given. More... | |
