Class Description

wire deformer function set

MFnWireDeformer is the function set for wire deformers. Wire deformers modify geometry based on its proximity to controlling wire curves. As the wire curves are modified, the parts of the geometry close to the curve will follow.

The wire deformer is actually a small network of dependency nodes in the dependency graph. This function set is provided to make manipulation of the network easier. The main deformer node should be given to this function set as its object.

float rotation ( MStatus * ReturnStatus = NULL ) const

Returns the rotation value for this deformer.

The rotation value determines how much the tangency of the wire curve affects the deformation. When the rotation value is 0.0, the deformation will be linear.

This will provide more natural deformations when the wire curve is twisted with respect to its original position. The surface will pull towards the wire in an arc rather than in a straight line.

Parameters

[out] ReturnStatus return status

Returns: The rotation value

Status Codes:

MS::kSuccess operation successful
MS::kFailure function set does not have a valid object

MStatus setRotation ( float rotation )

Sets the rotation value for this deformer.

The rotation value determines how much the tangency of the wire curve affects the deformation. When the rotation value is 0.0, the deformation will be linear. The geometry will pull straight towards the wire. When the rotation value is 1.0, the tangency of the wire curve is taken into effect.
