[vtkusers] OBBTree vs ModifiedBSPTree

[Jothybasu Selvaraj]

Hi all,

What is the actual difference between vtkOBBTree and vtkModifiedBSPTree?

>From their names I can understand that OBBTree partitions data by opotimal
BB and BSP in some other method. I am trying to find line vtkPolyData (2D)
intersection.

For the same line and polydata, OBBTree say it intersects and
ModifiedBSPTree syas it doesn't.

BTW, polydata is perpendicular to the line.

Any clarification?

Thanks
