[MAGNIFICATION] Life through a lense

Sorry for not seeing this earlier. Nice effect and props for the source.

People have been very kind to me here, thank you for the nice comments, in truth it's only a hack, it's not even a true lensemap that's why it runs fast, it's just a straightforward horizontal interpolation, a flat square is just stretched between the edges of a circle. It's the way almost all the oldschool lenses had to be made once upon a time.

There are better (and probably just as fast) methods for doing this by precalculating a real sphere and just changing the colour of the texels to do a false refraction on the image underneath it, it'd probably look much nicer

Yup, but if this was being judged as part of a competition where you had one hour to hack together a magnification effect, I'm sure you wouldn't have many competitors for first place.

Hehe, there lies the problem, lots of people here did a better job, I don't expect to get anywhere near the top 5 even.

Even though I now understand how it was done, it's still a cool effect.

I don't know how to do it in Flash, though it may be possible.
