Hi Ho there people!

I heard a lot about the trace-function, but, since I didn't download a
beta
of 3.5 yet, I don't know, how it actually works and what it's suitable
to
do.

I've heard that it can only check if two objects intersect, and that
certain variables can be used to check the actual intersection point.

Is there a function, with which you can take a position, shoot a ray
into a given direction, and have POV-Ray return the distance until
the ray hits an object?

Or have a gotten something completely mixed up?

It's just that I'm wondering, how difficult I/O really is with
particles,
and since I've begun thinking about creating such a system some day,
I'd like to think in correct terms, instead of believing something
utterly
useless...

Tim
