Hi!  Recently downloaded POV 3.5 and am trying to learn some of the new
features.

One thing I hoped to do was combine a heightfield with a granite pattern
(for mountains) with some other math functions (something like a sin
function so the edges of the mountains reduce to the foothills.)  Yet it
appears that the pattern cannot be mixed with the math functions - is
this true?  Or am I overlooking something.

Also, once I have my hightfield, I have heard that there is a way to
find intersections, so that I can place objects correctly on the
mountain.  I saw the <mumble mumble>Intersection function which takes a
vector, a position, and a third parameter, but I am not seeing what that
third parameter is?  Or am I going about this wrong?  Any help would be
appreciated.

Thanks!
