Fisheye wide angle spherical distortion issues
Hi all
I have followed both the fisheye and wide and distortion threads on this forum but I am confused as to how to create a fisheye lens effect.
Can anyone shed some light on it?
I have tried to drop a transparent material (with 1.5 refractive index) onto the camera but it does very little. I guess I am making some fundamental mistake. Any ideas? Also can you explain what is meant by Adam’s comment “You’ll have to use Best AA because the transparent material kills Object AA. ” It has confused me no end.
You’ll probably guess I am relatively new to all this!
Many thanks for your help

Sorry I confused you. 🙂
First, you can’t just put a transparent material on a camera to achieve the effect. You have to actually model lens, place the material on the lens, and then have the camera look through the lens in order to achieve the effect.
Now, you may have noticed that the default “Geometry” anti-aliasing does not work through transparency. Geometry AA attempts to speed up rendering by only effecting object edges. Notice that it also does not smooth textures?
So naturally if your whole scene is being viewed through a transparent material, you will not have any anti-aliasing with Geometry AA. In contrast, “Best” anti-aliasing applies AA to the entire frame regardless of transparency or other effects.

Not a problem, I am easily confused!
I’ll try these out, thanks for your help.
