refractive distortion question updated with pics


Recommended Posts

Have you tried playing with lens, tube, water reflection, etc.?

 

The Doctor: There was a goblin, or a trickster, or a warrior... A nameless, terrible thing, soaked in the blood of a billion galaxies. The most feared being in all the cosmos. And nothing could stop it, or hold it, or reason with it. One day it would just drop out of the sky and tear down your world.
Amy: But how did it end up in there?
The Doctor: You know fairy tales. A good wizard tricked it.
River Song: I hate good wizards in fairy tales; they always turn out to be him.

thats not light refraction its image distortion due to thr refractive qualities of looking at glass ,accomplished with mild dents or sine waves or a combination of several distortive plug ins. and that bottle isnt true to life distortion either since it doesnt warp around the refractive glass areas.

retired from PDN forums. Later dewds

It does look like it's just done hoping for the best results. You can't really distort things like that easily, because it changes for every picture. What you'd need for this would be a plug-in that detects edges (transparent VS opaque), then lets you choose the altitude you want, and distorts according to that. I'm not sure I'm being clear :|
