Dear POV-Experts,

I have tried to get the helix function running --- it didn't work.
I then tried out the spiral function (f_spiral()) in the same setup -inside a
standard isosurface definition - and it worked right away as expected, so it's
not the fault of the test setup.

The best i could get out with the helix1 function was a cylinder in y-direction
when i used P3<P2 (Major < Minor radius!) unlike told in the help file.
I tried various values for P2 and P3, what changed the radius of the cylinder
but didn't have any other effect, no helix to be seen.
I also tried different values (i.e. 0.1, 0.5, 1, 2, 10) for P1 and well... no
effect.
For P4 i also tried 0 and 1 without effect.
P0=1, P5=2, P6=0;

[ f_helix1(x,y,z, P0, P1, P2, P3, P4, P5, P6) ]

Has anyone successfully created a helix with this function and can provide me
with a piece of working code or tell me what i did wrong?

Thanx and Merry Christmas

Volker
