absorbance is set on default 0,01 and abbe is 120 for all the dielectrics involved (four). that mess that you see there is due to the coplanarity (does the word exist?) of the meshes of wine and glass.

almost..the red line has to be iorglas/iorliquid

Actually, on second thought... NO... it should be the other way around:
So IOR from glass to liquid=1.33/1.57=0.847.

rivoli thx

Try putting IOR below 1. Doesn´t work, 1 is the lowest value possible.

Though it certainly is not obvious, this is a serious limitation:

If you would liek to render underwater scenes and submerse your camera, it makes sense to use 1/IOR to create air bubbles. Obviously this is ~0.7.

Does M~R realize when the camera is put into a optical active body?

Thomas, I don't think that's correct, it should be glassIOR/waterIOR because the light is coming from the glass and entering the water.

check this page:
http://schools.matter.org.uk/SchoolsGlo ... index.html

The settings we have for the dielectrics IOR, are absolute IOR, meaning the IOR when compared to vacuum (light coming from vacuum into the medium).

Yes but did you check the calculations ? I account for the direction from glass to liquid: IORGl,Lq= VelocityInGlass/VelocityInLiquid.

[Mihai]

But why do you divide it the other way around? I think it's

light coming from material 1 (glass)
____________________________

light coming into material 2 (liquid)

where the hell i come to this earth... here light sux!

[Mihai]

You are doing wrong here Thomas:

Vcg=speed of light in glass = Vc/IOR glass= 1/1.33

That's wrong, the VCg is already 1.33, that's the glass's absolute IOR, ie when comparing light coming from vacuum and entering glass.

The calculations are correct.
You are confusing speed of light in the glass medium (Vcg) versus index of refraction (IOR)

[tom]

I account for the direction from glass to liquid: IORGl,Lq= VelocityInGlass/VelocityInLiquid.

Thomas this was your statement, but what about the formula on your drawing?
Things going worse here
My brain started to flow out from my ears....

Don't you see where it says IORgl,lq = Vcg / Vcl. (just replace Vcg and Vcl with their equivalents from above)

Please, lets not get stuck on basic algebra

If there is an error it is probably in my concept but not in the math (I know I can do the algebra right)

oh god, that's not that bad. i've nothing left to flow in any direction after seeing that last drawing thomas showed us.

[rivoli]

Please, lets not get stuck on basic algebra

my goodness, are you trying to drive me crazy thomas? what other kind of algebra do you think we should stuck on then?

[tom]

thomas, please correct that picture then because i looked at it tons of time and there writes the opposite of what you say

-edit: oh no.. you're right thomas... one is velocity and the other is IOR
