Hi,

I don't know how to post picture files, so I just attach a example of the
povray script that generates this problem.  The scene shows the plane that
intercepts the two merging spheres.  I want to hide this plane and only
trace the extrior surface.  Is there a way to accomplish this?

merge{

sphere{<0,3,0>, 2.0 }
pigment{color rgb<1,1,0> transmit 0.8}
}
/////////////////////////////////

Thanks.
