how do you create a successful look of glass? (Nicole)

[Egg Bramhill]

Nicole raised the above question in a recent thread.
The problem with Glass is that it normally has no colour. ie As used in a window.
If you look at a window full on, it has no colour, perhaps a tint, but often impossible to see.
Like Chrome etc it is only visible due to highlights and shading firstly and refraction secondly.
Below is my attempt to draw a clear uncoloured glass. The refraction isn't correct but it's a good cheat.
Klaus also gave some great advise recently by stating that all reflections are never only B & W but have faint colour tints, which I've used below.

It is difficult to see the shapes that make up the glass due to feathering and transparencies so please view the image below as a further explanation.

Eric,

what can I say ??
This is the most amazing example for glass done on a computer screen that I have ever seen!
It's perfect because it's so subtle and it really needs a master to come up with believable, uncolored glass.

Looking at it with eyes wide open ...

A wonderful tutorial Egg.

I rated it earlier, but have to ask - where did you get your random patterns from? Did you photo a glas on a plan background or scan somethig in? Or did you just make them up.

Nice one Egg! I thought the whole thing was a bitmap until I saw the wireframe!

Egg. You are going to be printed and posted to my bulletin board next to my PC. The second posting tied things together beautifully. It was very easy for me to understand.
