[vtkusers] Question about model bounds

[Fabrice Vincent]

Hello

I think that :

(-1,1.5,-1.25,1.25,-1.25,1.25)=(x1,y1,z1,x2,y2,z2)  are the coordinates of two opposite corners of a
box.
SetSampleDimensions(25,25,25)  defines the number of samples  in x , y and z directions.

So,  you will get a grid of 25*25*25 points inside the specified box.
