Hi, there,

    Here is some stuff I played with since the last
two days:

#macro Geo_flower ( rad_whole_thing, step_num, line_thickness, smoother,
circonf )

I made this macro quite quickly,  and it works well.
In fact,  the only problem is that this macro doesn't
have a great usefullness !  But it doesn' t matter,
I did it as a challenge,  in trying to ask the computer
to find the good radius',  dependently of the number
of steps a given shape has been programmed for.
Also,  a "smoother" keyword give the possibility
to smooth the curves...  The whole thing is done
using csg and trig calculations.

Is this an idea of some interest ?...  Or should I move
somewhere else ?

Hello,

Sure this has my interest!  Will you give me the macro?   :o))   I'd like to
examine it, and about usefulness, well, we never know...

I did something similar a long time ago using plain spheres. The next
step is to start moving them around the third axis as well so you can
create knot rings and the like.

Any learning experience is a good thing when it comes to POV-Ray.

I have to look at this code one last time,  because there are a
couple of things which are not working the way I want!
The code will be on "binaries.scenes-files" quite soon;  have
a look at it,  may be you will find something we could add
to improve the concept...  In fact,  the idea came to me in
remembering such old 2d drawing programs as "Free_Hand"
and Illustrator;  those drawing softwares always have an
option to draw geometric shapes like stars or rounded coins
gearing_like stuff... Giving the option to choose the number
of steps to be draw, around a circle.

Thank you,     Alex

I did it with torus'

I think you mean that one could push this idea a bit farter,  and draw
the
wavy shapes vertically,  instead of horizontally...  Isn' t it ?!

I think here is what Josh E. was speaking about:
the knoted rings...

P.S. ( the macro is on "scene-files"...  look for "Geo_flower")
