## Detailed Description

Nurbs Surface function set for dependency node data.

MFnNurbsSurfaceData allows the creation and manipulation of NurbsSurface data objects for use in the dependency graph.

If a user written dependency node either accepts or produces Nurbs Surfaces, then this class is used to extract or create the data that comes from or goes to other dependency graph nodes. The MDataHandle::type method will return kNurbsSurface when data of this type is present.

If a node is receiving a Nurbs Surface via an input attribute, the asNurbsSurface method of MDataHandle can be used to access that input Nurbs Surface.

If a node is to create a Nurbs Surface and send it via an output attribute, a new MFnNurbsSurfaceData must be instantiated and then the create method called to build the actual data block as an MObject. This MObject should be passed to the MFnNurbsSurface::create method as the parentOrOwner parameter so that the Nurbs Surface will be constructed inside the data block. The MDataHandle::set routine is then used to pass the data block down the connection.

Examples:

  fullLoftNode.cpp, and simpleLoftNode.cpp.

`#include <MFnNurbsSurfaceData.h>`

## Constructor & Destructor Documentation

MFnNurbsSurfaceData | ( | MObject & | object,
|  | MStatus * | ReturnStatus = `NULL`
| ) |  |

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

  [in] | object | The MObject to attach the function set to
  [out] | ReturnStatus | the return status

Status Codes:
  - MS::kSuccess if the function set is successfully attached
  - MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject

MFnNurbsSurfaceData | ( | const MObject & | object,
|  | MStatus * | ReturnStatus = `NULL`
| ) |  |

Constructor.

Class constructor that initializes the function set to the given MObject.

Parameters:

  [in] | object | The MObject to attach the function set to
  [out] | ReturnStatus | the return status

Status Codes:
  - MS::kSuccess if the function set is successfully attached
  - MS::kInvalidParameter if the MObject does not represent a valid Maya object or if the function set is not allowed to attach to this MObject
