Ah, all right. Understood now.
That's a kind of protein.

BTW it is a population, an ethnic group, it was an antic civilization if you
want but there is only one human race: human :)

BTW is an ethnic group? Well I've known new things about population. All is
interesting.
Any ideas about my question?
Thanks,

Here is a macro given to me by Frank Sputnik some time ago. It is set
up for Moray so I have included the camera and lights. (Moray uses an
alternative coordinate system)
To increase the gap make SpringHeight > 2;
camera { // Camera Camera01

Sorry for that off topic drift and I had no answer to your question.

I usually suggest isosurfaces for just about everything, but in this
case a sphere_sweep is probably easier. Here's some code to get you
started.
The UNIT is one helical strand with an extension. The path follows a
helix shape until N=P2, then starts to do other things. Four copies of
the UNIT are used to create a double strand helix with extensions at
each end.
I start the sphere_sweep at N-1, to make it much easier to join the four
UNITs correctly. Since the sphere_sweep starts at the second point, it's
tricky to get them to match in the middle if the second point is N=1;
Try different values of A, B, C, D, E and F.
You could also turn the UNIT into a macro, and produce four units with
different parameter settings, so that you get differently shaped
extensions.
#version 3.6;
global_settings {assumed_gamma 1.0}
camera {location <0,0,-10> look_at <0,0,0> angle 35}
background {rgb 1}
light_source {<-30, 100, -30> color rgb 1}
// ----------------------------------------
#declare Points=30; // total number of control points
#declare P2=22; // control point where extension starts
#declare R1=0.1; // minor radius
#declare R2=0.3; // major radius
#declare A=25.0; // controls turniness
#declare B=1.5; // controls height
#declare C=0.4; // controls sideways spread of the extensions
#declare D=2.0; // controls the stretch of the extensions
#declare E=0.2; // controls waviness of extensions
#declare F=1.5; // controls frequency of wave extensions
#declare UNIT=
sphere_sweep {
cubic_spline
Points,
#declare N=-1;
#while (N<Points-1)
#if (N<P2)
#declare X=R2*sin(A*N/Points);
#declare Y=B*N/Points;
#declare Z=R2*cos(A*N/Points);
#else
#declare X=R2*(1+(N-P2)*C)*sin(A*N/Points);
#declare Y=B*N/Points + sin(F*A*(N-P2)/Points)*E
+ B*D*(N-P2)/Points;
#declare Z=R2*(1+(N-P2)*C)*cos(A*N/Points);
#end
<X,Y,Z>,R1
#declare N=N+1;
#end
pigment {rgb 1}
no_shadow
}
object {UNIT}
object {UNIT rotate y*180}
object {UNIT rotate z*180}
object {UNIT rotate z*180 rotate y*180}

Thanks Stephen and Mike and the other people.
Now I'm going to study your codes and I will tray them.
I will post questions later.
Thanks a lot,
Oleguer
