Well the best would be something that could export to illustrator format. But powercalc is ok for now. Thanks, LOTR Junkie.

I feel like trying this myself. Does anyone know of a good freeware/open source mathematical function graph plotter?

Try focusing a hdr image lol!!

Also there is alot of abberation in those lenses, does anyone know what the mathematically precise curve shape for a lens is?

Too bad, I can still see some noise

unless you are stanley kubrik with his f0.7 lenses

if the overlapped images were HDR that would be awesome.

The camera should be in the EXACT centre of the sphere, otherwise it looks like you took the photo with your stomach

EDIT: why not use a HDR image

Yes but how long would it take to place all those exit portals?

Is exposure time going to be tied to motion blur if you ever do that?

Or only tied to the image brightness like in maxwell?

this is AWESOME

Hmm, aren't exit portals kind of a biased idea. Surely with the perfect sampling algorithm you wouldn't have to tell the computer where the light was coming from.

For example if (sometime in the future ) I was do to an animation where the exit was constantly changing and distorting
