deBoolean dePolyABT::SetSplitWeights (  deFloat    Axis,
deFloat    Volume,
deFloat    FaceBalance,
deFloat    NumSplit
) 
 

set the weighting values for determining split plane locations. sum of all weights should be 1.0, and will be normalized if it is not. recommended to put most weight into FaceBalance to get more adaptive splits, but leave some weight in the others to avoid degenerate splits.

Parameters:
Axis weight towards largest axis
Volume weight towards center of chunk volume
FaceBalance weight towards equal number of faces on each side of split
NumSplit weight away from inducing splits of faces in a node
