Ok, the CVS version shows a different effect, but still not exactly what I 
need.
The documentation says :
"ssgLOS intersects an arbitary vector whose direction is defined by 's'. "

So I defined a vector with length 1.0 pointing to the direction according to 
the camera angle. It comes up with intersections very near to the camera.
After multiplying it with 10.0 it intersects with objects farther away, but it 
will miss the ones directly in front of me. It seems the length of the 
"direction vector" matters, but it looks like it's more an intersection of a 
point rather than a line starting from the camera with a specified or 
infinite length.

Is there an example for the usage of ssgLOS ?

Thanks,
Rolf
