Title: Here's a lens mapping thing...
Post by: Dr_D on December 11, 2006

It's more of a tutorial than anything. It was a little less detailed before, but I decided to add a couple more effects to it. The code is pretty well commented, so if anyone wants easy lens mapping, here it is. ;)

By the way, what does the karma do? Can I buy stuff with it?  :clap:

Thanks for posting the source code, karma  :P.  Had you thought about pre-computing the effect?  Basically for each pixel in the square containing the lens, you could store an x,y offset which tells you where to get the pixel from.

Yeah, it would surely be faster using an array to store pre-computed coords, but I was afraid it wouldn't be as easy to understand.

Only in the afterlife.
