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?

///////////////////////////////
camera {direction<0.0,0.0,  -1>
 location <0.0 , 0.0 , 15.0>
 right 1.3333333660*x up y
 }
#default { finish{phong    0.500 ambient    0.120 diffuse    1.080
phong_size 15.000000}}
light_source{<4000.0001,4000.0001,9978.2371>  rgb<1.0,1.0,1.0> }
plane{z , -10.4444
 pigment{color rgb<0.0000,0.0000,0.0000>}
 finish{phong 0 specular 0 diffuse 0 ambient 1.0}}

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

Thanks.

Tom
