[vtkusers] vtkCamera Question

[Fatima Zahra El Filali]

Hello,

I am having some trouble with vtkCamera.

Here is what I am trying to do:

I am viewing a Structured Grid of dimension 500x500x100 and would like to
put the camera in the middle of the grid and look out.

When I set position to the middle of the grid 250x250x50 and focal point to
the default (0,0,0) I cannot view anything.

Any hints? or idea as to what coordinates I should be using?

Thanks
Fatima
