Thank you a lot byt I am affraid that the software I use
(SwissPDB viewer - http://www.expasy.org/spdbv/) uses some
very old syntax
(#version 3.1 // this scene uses POV-Ray 3.x syntax)
Is there still some possibility to add depth.pov into this?
Thanks a lot again

The easiest and more flexible way would probably to just use a texture with
deptch-cueing.

What you do is use the spherical pigment and apply an appropriate color_map
to it. The only things it needs is the location of the camera. Here's the
code you'd need for that:

#declare Camera_Location = <0,0,0>;
#declare Depth_MaxDistance = 10;
#declare Depth_MinDistance = 0;
#declare Depth_MaxColor = <0,0,0>;
#declare Depth_MinColor = <1,1,1>;

#declare Depth_Pigment=
pigment{spherical
scale Depth_MaxDistance
color_map{
[0 rgb Depth_MinColor]
#if (Depth_MinDistance) [Depth_MinDistance/Depth_MaxDistance rgb
Depth_MinColor] #end
[1 rgb Depth_MaxColor]
}
translate Camera_Location
}

Then, to match the background color to the furthest depth, just use
background{rgb Depth_MaxDistance}

Just apply the pigment to the object/molecule AFTER the parts have been
moved into place, otherwise the texture will get moved as well, which
destroys the effect it's trying to achieve.

Hope that helps!

Regards,
Tim

It should still be possible to find a copy of MegaPOV 0.6 which uses 
POV 3.1 type syntax. Then you just add something like this to the scene

global_settings {
 post_process {depth {10,100}}
}

and change the version number to 

#version unofficial MegaPov 0.6;
