virtual void GT_PrimMeshSplitParent::partitionElements ( const GT_PrimMeshSplitRange range,
const UT_BoundingBox full,
bool *  left,
int  start_seg = 0,
int  end_seg = 0 
) const
protectedvirtual

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 bool GT_PrimMeshSplitParent::partitionRange ( const GT_PrimMeshSplitRange range,
const UT_BoundingBox full_box,
GT_PrimMeshSplitRange left,
GT_PrimMeshSplitRange right,
int  start_segment = 0,
int  end_segment = 0 
)
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 primtives at segment 0.

virtual void GT_PrimMeshSplitParent::rangeElementBounds ( const GT_PrimMeshSplitRange range,
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.

virtual void GT_PrimMeshSplitParent::rangeEnlargeBounds ( const GT_PrimMeshSplitRange range,
UT_BoundingBox full,
UT_BoundingBox  boxes[],
int  nsegs 
) const
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.

virtual bool GT_PrimMeshSplitParent::refine ( GT_Refine refiner,
const GT_RefineParms parms 
) const

Methods from GT_Primitive

Reimplemented from GT_Primitive.
