Physically correct modelling of glass

There's a section in the manual about this already, but since it's a little out of date and cannot be directly linked to, I've created a new page in the online manual about correctly modelling glass (and also a bit about rendering interior and exterior shots, using glass acceleration).

Please have a look and let me know what you think!

Only thing to mention could be:
... The simplest way to correctly model a glass pane, is to take a thin box (e.g. a cube squashed in one dimension) and apply an Indigo glass material to it ...
Since it is for beginners you should mention that a "Indigo glass material" is a specular material with IOR of 1.52 and transparency enabled. To fully bank on preset materials will keep the starting user inexperienced in Indigos material system...

Nice! It;s a good start.

However, glass is such a fascination material that just barely scratches the surface. Not even window glass is really always simple. How about window glazings for example etc.

Ok, now I also become greedy :twisted:
How about a line about advanced tabulated based glass like this one from galinette:

Also a few words on cauchy B (with example image) would be maybe nice...

You can also turn the normal of the edges and assigned a correct material with the correct medium.
