[vtkusers] Get all the bounding boxes

[Jalal Miftah]

Ah...

Thanks for you reply,

For now I was using a transform filter to rotate my point cloud in all the 
directions, and recompute a new bounding box.

I still don't understand what vtkOBBTree is doing. Is it a tree with a lot 
of different bounding boxes? 
And it can help me, do you know how to get the minimum bounding box? 

Best regards,

Jalal

Hi, 

Given a point cloud, you have an infinity of bounding boxes (if you 
translate/rotate the point cloud for example), that what I mean for "all 
the boxes". 
I am not looking for the smallest possible, but something in between (the 
distance between my point cloud and one surface of the bounding box should 
be minimum). But yes basically I need to find one box among all of them. 

Hope this is better. 

Thank you 

Jalal 

Unfortunately I believe the answer is, "No, VTK doesn't have anything like 
this." Maybe someone else can chime in if they've seen such a feature?
