connectivity

[Jordi Cabot]

Hello, 
Is there any way to obtain the bounding box that encloses an irregular
surface given 4 points of this surface. The bounding box computation
that I found in vtk gives the max an min coordinates of these points,
but if the surface has irregularities, some parts of the surface defined
by this 4 points may be outside this bounding box.


Thanks for your help,

Jordi
