## Constructor & Destructor Documentation

MnRigid | ( |  | ) |

Default constructor.

The parent class will set the instance to contain nothing.

## Member Function Documentation

MStatus setTopology | ( | const int | numFaces,
|  | int * | numVertsPerFace,
|  | int * | faces,
|  | const int | numEdges,
|  | int * | edges
| ) |  |

Search for all occurrences

sets the topology of the underlying N Object.

Before calling other methods, this must be the first method you call once the cloth object is created.

Parameters:

  [in] | numFaces | number of faces
  [in] | numVertsPerFace | an array of size numFaces, where each element describes the number of verts on that face
  [in] | faces | an array containing the actual face description. Each element is a vertex index.
  [in] | numEdges | number of edges
  [in] | edges | an array containing the edge description. Each element is a vertex index.

Returns:
  - MS::kSuccess the operation was completed successfully
  - MS::kFailure the operation failed

MStatus createNRigid | ( |  | ) |
