Is there a way to read the coördinate of a object in an animation?
I'm quite new to animation in POV (for Windows) and got stuck on this
problem a few times.
Suppose I made a cylinder, originating in <0,0,0> and ending in <0,1,0>.
Including the cylinder and a sphere at the end of it in a object, gives me a
stick-like object. When I would rotate the stick around, say, the Z-axis, is
it possible to track the exact coördinate of the (centre of the) ball? I'd
like to be able to use the tracked coördinate to move another object in the
same scene.
Thanks in advance,
Remon Koopmans,
the Netherlands.

The tools you want are vrotate and vaxis_rotate. Look under vector
functions in the docs. Vrotate will give you the new coordinates
resulting when you apply a rotation (about <0, 0, 0> = "rotate <a, b,
c>") to a point, and vaxis_rotate will do the same if you give it an
arbitrary axis of rotation and number of degrees.
