I just saw Corey's posts so I thought I'd continue the theme...
Rendering Trick for Simulating Perspective
I've been experimenting with using virtual lenses for creating perspective views when the SolidWorks settings aren't giving me what I'm looking for.
What I did was to create a revolved surface, shaped as one half of a magnifying glass lens and assign a refractive see-through material to it.
I zoomed in far enough until I was looking 'through' the lens, then I rendered the image.
Here is an example...The original video image I used as a reference was taken through a security camera, so I needed to capture that 'fish-eye' dealy.
Maybe this might help someone?
