Hello!
I am looking for a function that helps me with splines.
I want to give the function the ***exact*** start point (x1,y1,z1) and end
point (x2,y2,z2) of an spline and the height (h) of it - nothing more.
All other things should be figured out by the function.
The spline stands in a right angle to plane below.
The stuff in the function should be something similar to what you see below
the message.
A sphere i moved along the spline.
The Problem is to get the points ***exactly*** to a given start and end
position (x,y,z). I'd line to begin the first sphere exact at (above) the
star-point xyz.
I really like to have a functon doing it.
Thanks a lot!

#declare MySpline =

cubic_spline
-0.25,<-1, -1.6,-.85>
0.10, <-.87,1.05,-.85>
0.80, <.64, 1.1,.6>
1, <1.8, -1.4, 1.1>
}
#declare ctr = -.3;
#while (ctr < 1.2)
sphere {
MySpline(ctr), .05
pigment { rgb <0.5,1,0> }
}
#declare ctr = ctr + 0.01;
#end

This is the wrong group for this question. This group is for discussion of
the POV-Ray source code. Questions about using the POV-Ray should be asked
in either povray.general or povray.newusers.
