Detailed Description

Class for wrapping N cloth objects.

This class wraps the internal Maya representation of N cloth objects suitable for use with the Nucleus solver.

Examples:: testNpassiveNode/testNpassiveNode.h.

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
	)

sets the topology of the underlying N Object.

Before calling other methods, this must be the first method you call once the rigid 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 ( )

Creates the underlying Maya TnRigid and sets this class to wrap it.

Returns

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

MStatus setPositions	(	const MFloatPointArray &	positions,
		bool	startFrame = `true`
	)

Sets the positions of the vertices of the underlying nRigid object.

Parameters

[in]	positions	the array containing the position information
[in]	startFrame	whether this information represents the state of the object at the start frame.

Returns

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

MStatus setVelocities ( const MFloatPointArray & velocities )

Sets the velocities of the vertices of the underlying nRigid object.

Parameters

[in] velocities the array containing the velocity information

Returns
