Take note guys that glass only distorts background surfaces if the glass is solid, and is quite thick. If the glass is thin & hollow -- as in a watch face cover -- then distortion
might only occure at the edges, and only then
if the glass curves, not if it's flat.
Put a clear glass cup down on it's side, on a news paper/magazine and look at how it distorts the print. Chances are that it will only do so toward the edges (
where the glass bends)... otherwise, it will only 'magnify' the print. And a lot of times, the distortion seen around the edges is to strong to actually see any detail from the background surface. Usually you'll just see a dark outline;
unless you're looking right up close to the object.
This is the idea behind the effect in the "
Glass/Plastic Buttons" tutorial i wrote a while ago. Many people ask me why the paper stripes under the pill buttons is not distorted... and it's because the pill buttons are hollow, not solid. [slick]
Although i left that aspect of the effect 'open ended'... noone has yet thought of this fact. Everyone seems to think the glass buttons
should always distort. Not enough 'active imagination' being used it seems.
What for?
