Now, to say the truth, I'm stuck in a problem that seems a bug to me.
Trace() often doesn't work well with isosurfaces (every normal vector is
stored as <0,0,0> even if intersection occurs).
Or, better, sometimes it works fine like it should and sometimes it
completely fails. This happens only with isosurface landscape.
It's really a puzzle...
