[ REQ 5735]: Opacity

[p37039k at snakemail.hut.fi]

HI

I found your nice visualization program from www. 
However, I had some problems with opacity. You say
in manual pages that polygons should be presented
in off-file in following way

n p1 p2 .. pn-1 r g b opacity

I used floating points between 0 and 1.0 for r, g, b
and opacity. When I load my off-file, I can't see
any difference although I would have changed opacity-
values. (I'm visualizing a torso model where skin 
should be a little bit trasparent and therefore
lungs and heart could be seen). Could you please
give me some tips how to solve the problem.

Thank you very much.
