Constructing a Smoothed Surface

The function

MbResultType SplineSurfaceSmoothing( const MbSplineSurface &  surface,
                                           size_t             udegree,
                                           size_t             vdegree,
                                           MbSplineSurface *& result );

smooths a copy of the source surface.

The input parameters of the function are:

• surface - the source spline surface;

• udegree - the new order of the spline surface in the first surface parameter;

• vdegree - the new order of the spline surface in the second surface parameter.

The output parameter of the function is the smoothed copy of the source surface result.

If successful, the function returns rt_Success; otherwise, it returns an error code from the MbResultType enumeration (see mb_operation_result.h).

The function is declared in the file action_direct.h.

The function smoothes the source surface surface without changing its spline orders or the number of control points. The smoothing is controlled by the udegree and vdegree parameters, which must be greater than the corresponding spline orders of the source surface.
