const

Multiply this transform by a single matrix. This applies the matrix to all the embedded transforms.

void GT_Transform::setMatrix	(	const UT_Matrix4D &	xform,
		int	segment
	)

Initialize the matrix

void GT_Transform::setMatrix	(	const UT_Matrix4F &	xform,
		int	segment
	)

Initialize the matrix

GT_DataArrayHandle GT_Transform::transform	(	const GT_DataArrayHandle &	src,
		int	segment = 0
	)			const

Transform a data array (using the type info on the array)
