[Sidefx-houdini-list] Warped Camera Lense

there is a lens curvature control (it's not there by default- you have to add it
by clicking on the gear...)
but it doesn't do anything in the GL view, so your designer wouldn't have been
able to preview it. It only works in the renderer.

Quoting Adam Glazier <adam_glazier at yahoo.com>:

> angle lense.  The only controls I found in the camera object that seemed to
> exaggerate things was Focal Length and Aperture, and both seemed to do
> identical things.  The focal length warps the cameras output, but in a very
> straight and linear way.  Where as the look I am going for is very bowed
> where straight lines could never exist near the edge of the frame.
