[vtkusers] question about using vtkOBBTree to find minimal bounding box

[Gideon Valch]

Hello all,

I'm a relative newbie to VTK and I've been trying to figure out how to use
vtkOBBTree to draw a minimal bounding box.  I've looked at the previous
postings in the archives...and while they've been helpful,  I still think
I'm missing something.  How is the box formed from the axes?  Please see
attached image.  It is a screengrab of the Stanford HappyBuddha (stand
right) with axes drawn using vtkOBBTree.

 I've included the python program.  Any help would be appreciated. I'm not
sure how size and corner are used with the 3 axes (max,mid and min) to
define the bounding box.


Thanks,
Gideon
