[vtkusers] what is a scene's default camera focal point?

[Mark Wyszomierski]

Hi,

I've created a scene with just one volume. I haven't modified any
camera settings.

Does the camera automatically set its focal point to the center point
of the volume? Or in general, does the default camera just pick as the
focal point the center of the scene (the center which encompasses all
actors) as soon as the scene is first rendered?

Thanks,
Mark
