Description

The operator get_ncc_model_paramsget_ncc_model_paramsGetNccModelParamsGetNccModelParamsget_ncc_model_params returns the parameters of the NCC model ModelIDModelIDModelIDmodelIDmodel_id that were used to create it using create_ncc_modelcreate_ncc_modelCreateNccModelCreateNccModelcreate_ncc_model. In particular, this output can be used to check the parameters NumLevelsNumLevelsNumLevelsnumLevelsnum_levels and AngleStepAngleStepAngleStepangleStepangle_step if they were determined automatically during the model creation with create_ncc_modelcreate_ncc_modelCreateNccModelCreateNccModelcreate_ncc_model. Furthermore, this output can be used to check the parameters if the model was read with read_ncc_modelread_ncc_modelReadNccModelReadNccModelread_ncc_model.

Execution Information

• Multithreading type: reentrant (runs in parallel with non-exclusive operators).
• Multithreading scope: global (may be called from any thread).
• Processed without parallelization.

Parameters

ModelIDModelIDModelIDmodelIDmodel_id (input_control)  ncc_model → HNCCModel, HTupleHHandleHTupleHtuple (handle) (IntPtr) (HHandle) (handle)

Handle of the model.

NumLevelsNumLevelsNumLevelsnumLevelsnum_levels (output_control)  integer → HTupleintHTupleHtuple (integer) (int / long) (Hlong) (Hlong)

Number of pyramid levels.

AngleStartAngleStartAngleStartangleStartangle_start (output_control)  angle.rad → HTuplefloatHTupleHtuple (real) (double) (double) (double)

Smallest rotation of the pattern.

AngleExtentAngleExtentAngleExtentangleExtentangle_extent (output_control)  angle.rad → HTuplefloatHTupleHtuple (real) (double) (double) (double)

Extent of the rotation angles.

Assertion: AngleExtent >= 0

AngleStepAngleStepAngleStepangleStepangle_step (output_control)  angle.rad → HTuplefloatHTupleHtuple (real) (double) (double) (double)

Step length of the angles (resolution).

Assertion: AngleStep >= 0

MetricMetricMetricmetricmetric (output_control)  string → HTuplestrHTupleHtuple (string) (string) (HString) (char*)

Match metric.

Result

If the handle of the model is valid, the operator get_ncc_model_paramsget_ncc_model_paramsGetNccModelParamsGetNccModelParamsget_ncc_model_params returns the value 2 ( H_MSG_TRUE) . If necessary an exception is raised.
