Watched this ST episode again, recorded on a VHS tape several years ago. The 
colors very faded. One of my favorites of Star Trek. I'm part trekkie 
anyhow. Maybe you know which show this was, too. Always wanted to put that 
enormous spaceship together in POV and so I finally did over the past couple 
days. The Enterprise is just some spheres, cylinders, cones, boxes.

What took me the longest time to do was finding a way to put the spheres all 
around into another spherical shape. I knew people had done plenty on that 
subject, uniform or random distribution. I didn't want to copy someone else 
so I tried looking for just a simple equation. When I did find one it was 
chaotic, something didn't seem right anyway, so I changed it around until I 
got what you see here. It still isn't like the ship, which had a hexagonal 
pattern.

Attached is three of the frames (with added force field) . The animation 
itself (no force field) can be found at my site via the Animations link. 
Nothing perfected at all, just playing with POV once again.

Thanks for looking!

Nifty. I raise a glass of green Tranya in your honor.

Nicely done!  (One of my favorite ST episodes as well.) Actually, your
multi-sphere placement DOES look hexagonal to me; good job.

I seem to recall (a fading memory...kind of like your video ;-)  ) that the
small spheres may have been larger/closer together. Filling up more of the
intervening spaces. Just a guess.

How about posting a larger image of your Enterprise model? Looks good.

Thank you, Ken. Maybe depends on how you look at it. It's actually spiraling 
lines, with a twist. I've used more than one set of spheres for the 
yellow-white group by changing the incremental value added in the other 
loops and using a slightly different sphere size. It's terribly sloppy 
because that put spheres within spheres but it helped get variances in the 
pulses of light without trying to find other ways to pattern their 
locations.
Here's one loop:

#local n=500;
#local i=1; // initial value. could begin at 2 or ?

#while (i<=n)

#local h = -1 + 2*(i-1)/(n-1);
#local theta=acos(h);

#if (i=1 | i=n) // need to match above initial value
#local phi = 0;
#else
#local phi = i; // was: (phi[k-1] + 3.6/sqrt(N*(1-h^2))) mod (2*pi)
#end

sphere {
 <cos(phi)*sin(theta), sin(phi)*sin(theta), cos(theta)>, 0.06
 hollow
}

#local i=i+3; // would otherwise be +1 or +2

#end

Converted from what I found in a search, which used arrays instead, I almost 
got nowhere with it until I removed that modulus (did try correct syntax for 
POV) from phi and just used the increment value (was k, changed to i). It 
had been placing spheres pseudorandomly before that. Or I just didn't get 
the conversion right.

I was surprised to find out the smaller light spheres aren't two different 
colors in two different places, even after such a recent watching of the TV 
show being fresh in my mind. So, in one way it has more spacing and another 
it doesn't. I searched for Fesarius and found this:

Thanks again. You will see how crude it really is now! I think I've put the 
nacelles on there wrong, too low, but I haven't even checked against another 
model or picture until now. It was only put in there for the scale effect.

The nacels are much to low. They should reach compeltely over the saucer section.
Also, the pods 
holding the nacels are to thick, as is the section connecting the saucer to the
secondary hull.
