Determine which elements should be on the left side and which should be on the right side. By default, this will compute bounding boxes for the elements and split based on the largest box dimension.

	)

virtual

Given a bounding box for the range of primitives, partition the range of primitives by pivoting the indices. The default behaviour relies on the bounding boxes of primitives at segment 0.

		UT_BoundingBox	boxes[],
		int	segment
	)		const

pure virtual

Enlarge the bounding boxes for each element in the range. There is a bounding box for each element. Only the motion segment given should be considered.

		UT_BoundingBox &	full,

pure virtual

Enlarge bounding boxes for each segment over the range of elements There is be a bounding box for each segment.

virtual bool GT_PrimMeshSplitParent::rangeRefine	(	const GT_PrimMeshSplitRange &	range,
		GT_Refine &	refiner,
		const GT_RefineParms *	parms
	)		const

pure virtual

The range refine method should refine a range of elements into individual elements. If the method returns false, the mesh will be split into sub-meshes with smaller ranges.
