Description

create_scattered_data_interpolatorcreate_scattered_data_interpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorcreate_scattered_data_interpolator creates the interpolator ScatteredDataInterpolatorHandleScatteredDataInterpolatorHandleScatteredDataInterpolatorHandleScatteredDataInterpolatorHandlescatteredDataInterpolatorHandlescattered_data_interpolator_handle for the interpolation of scattered data, given as data points in RowsRowsRowsRowsrowsrows and ColumnsColumnsColumnsColumnscolumnscolumns with the corresponding measurement ValuesValuesValuesValuesvaluesvalues. With the parameter MethodMethodMethodMethodmethodmethod the algorithm is specified, which should be used for the interpolation with interpolate_scattered_datainterpolate_scattered_dataInterpolateScatteredDataInterpolateScatteredDataInterpolateScatteredDatainterpolate_scattered_data. So far, only the 'thin_plate_splines'"thin_plate_splines""thin_plate_splines""thin_plate_splines""thin_plate_splines""thin_plate_splines" are supported. This method interpolates on a global scale, which means that all points are regarded for the interpolation, no matter how far away they are. The influence of far points is correlated to where r defines the distance of two points. In comparison to interpolate_scattered_data_imageinterpolate_scattered_data_imageInterpolateScatteredDataImageInterpolateScatteredDataImageInterpolateScatteredDataImageinterpolate_scattered_data_image, create_scattered_data_interpolatorcreate_scattered_data_interpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorcreate_scattered_data_interpolator also supports subpixel coordinates for RowsRowsRowsRowsrowsrows and ColumnsColumnsColumnsColumnscolumnscolumns. After the creation, interpolate_scattered_datainterpolate_scattered_dataInterpolateScatteredDataInterpolateScatteredDataInterpolateScatteredDatainterpolate_scattered_data is called for the interpolation of the unknown values. By splitting up the creation (create_scattered_data_interpolatorcreate_scattered_data_interpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorcreate_scattered_data_interpolator) and the evaluation (interpolate_scattered_datainterpolate_scattered_dataInterpolateScatteredDataInterpolateScatteredDataInterpolateScatteredDatainterpolate_scattered_data) of the interpolator, interpolating at different data points in subsequent steps becomes more efficient since the interpolator has to be created only once.

The following parameters can be adjusted with GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name and GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value:

'alpha'"alpha""alpha""alpha""alpha""alpha":

The parameter 'alpha'"alpha""alpha""alpha""alpha""alpha" is a smoothing factor. For 'alpha'"alpha""alpha""alpha""alpha""alpha" = 0, all points passed in RowsRowsRowsRowsrowsrows, ColumnsColumnsColumnsColumnscolumnscolumns, and ValuesValuesValuesValuesvaluesvalues are interpolated exactly. With 'alpha'"alpha""alpha""alpha""alpha""alpha" getting larger, the interpolation smoothes the points in way that all interpolated points lie on a common plane.

Default: 0

Restriction: 'alpha'"alpha""alpha""alpha""alpha""alpha" >= 0

Execution Information

This operator returns a handle. Note that the state of an instance of this handle type may be changed by specific operators even though the handle is used as an input parameter by those operators.

Result

If the parameters are valid, the operator create_scattered_data_interpolatorcreate_scattered_data_interpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorCreateScatteredDataInterpolatorcreate_scattered_data_interpolator returns the value 2 (H_MSG_TRUE). If necessary, an exception is raised.
