[vtkusers] How to let vtkCamera 'take a picture'

[Shashwath T.R.]

Hi,

vtkCamera is really only a wrapper around the OpenGL viewport transform
matrix. It doesn't take pictures in the way that a real camera does...

If you want to save the image as seen by a particular camera, you can set
that up as the active camera in the renderer, and use vtkWindowToImageFilter
to grab the image from the render window. See CaptureImage in this Python
example:

Regards,
Shash
