Images were exported from jmol using the povray export.
I modified the povray export procedure to include two lights.
ffmpeg was then used to make a quicktime movie and convert
the quicktime movie to swf to be posted.  I use the quicktime
for my ppts, the swf was used just to post so that you could see
the effect.  The quicktime movie has much much higher
resolution than the swf.

Any suggestions as to where I should look in the code to try
to remove this effect?

Thanks,
Jay

Nice movie -- how do you do that?

Enjoy the effect. Actually, the two lines are passing THROUGH each other, 
hidden by the spacefill. More dramatic with

wireframe only

Hello All,

I think that there might be a possible problem with the representation of a 
double bond.
It seems that when a molecule with a double bond is rotated about an axis 
orthogonal to
the double bond and in the plane of the screen, the distance between the two 
cylinders
that represent the double bond changes.  This happens with perspective on and 
off.

Below is a link to a movie I made using jmol, where you can see the effect.
