Is there any way to achieve this effect in poser?
I'm trying to make a kid looking behind a snow globe and half his face is magnified. I know it has something to do with the fresnel- refraction value.
All of my efforts have ended up with an upside down reflection of other objects in the scene.
Any help would be appreciated :)
IIRC, the upside down reflection is due to a scientific principle I can't exactly remember the name of right now. Refraction? Anyway, the light is passing through two lenses which would be both sides of the bowl whichturns it upside down. Why you don't notice this effect in nature is because of a third lens, located on the back of your eye, which flips everything right side up again. It's not doing it in your render because that actual light never reaches your eye. So all you see is an upside down picture.
This is incorrect - total fantasy. (No insult intended) Please don't react to this. I am preparing materials to explain and demonstrate what is happening and what to do about it.
Being upside down is real - nothing to do with fake renderer vs. real eye.
Need some time though as this requires lots of test renders, in multiple versions of Poser, and I'm currently actually working.
Well, I admit, I don't know if that's the principle that's operating in Poser, but total fantasy???, it's the principle behind how a camera obscura works.
By fantasy I was referring to the "Why you don't notice this effect in nature" - because we do notice it in nature. It actually happens. A real glass ball shows the world upside down. There is no need to explain why we don't notice it. We do notice it.
It's not doing it in your render because that actual light never reaches your eye.
This ^^^ is a fantasy.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
