Well, obviously you just have to alter the points a little - either 
manually or automagically. If you have the glass points in an array, you 
can easily multiple every x-coordinate by some value (<1) or subtract a 
small value to keep the gap constant.

Or if you want a bit larger liquid you multiply with a value (>1) or add 
something.

I think the adding/subtracting is a better way actually because of the gap.

I don't know whether the liquid should be larger or smaller than the 
container. So I would also like to know what is the most accurate way to 
model that. Also, should there be specular reflections where the glass 
and liquid meet?
