Description
Retrieves information from a B-spline data structure.
NOTE:
The function ignores the output arguments with null pointers.
Synopsis
#include <ProCurvedata.h>
ProBsplinedataGet | |
( ProCurvedata* p_curve /* (In) The B-spline data structure. */ int* p_degree /* (Out) The basis function's degree. */ double** p_params /* (Out) The pointer to a ProArray of knots on the parameter line. Free this output using ProArrayFree(). */ double** p_weights /* (Out) In the case of rational B-splines, this is the pointer to a ProArray of the same dimension as the array of c_pnts. Otherwise, this is NULL. Free this output using ProArrayFree(). */ ProPoint3d** p_c_pnts /* (Out) The pointer to a ProArray of knots on control points. Free this output using ProArrayFree(). */ int* p_num_knots /* (Out) The size of the params array. */ int* p_num_c_points /* (Out) The size of c_pnts (and weights, if not NULL). */ ) |
Returns
The function successfully retrieved the information. | |
The specified data is not a B-spline data structure. | |
