Hi there, 

I do a bit of ray tracing with  Pov-Ray, and I'm trying to render some
mathematical knots. In particular I'd like to do the 3 verticed smooth
knot that ties itself 3 times.

I'm plotting spheres in a trajectory but I'm having problems placing
the spheres in the correct XYZ coordinates.I realise that this formula
to plot these points in space must be quite simple, but I cannot
fathom it out.

If anyone who reads this group, understands what I'm talking about,
and can offer some help, I'd much appreciate some assistance.

Thanks in advance.

Alan
