This is just an experiment with coloured lights, reflection, rotation, etc.
I can't work out why the green light appears to be faster than the blue
light when they're both in alignment.

Steve, what are you doing here? The base is stationary, the plinth is
rotating clockwise and the world is rotating counter clockwise. Argg! The
mushrooms are sprouting early this year :-)
camera back quite a bit and narrowing the field of view.

LOL! Well, I'm in the right location for them, but I don't drink tea!

Ok, I'll give that a try, and actually, that would be about the same
camera position and distance that I would want for my next animation, which
is going to be a merry-go-round or carousel. I'll use copies of the Poser
horse and doctor them up to look like proper carousel horses, but because I
want it (the carousel and horses) to spin authentically, how would I make a
horse do the up and down thing as it rotates?
(Anyone?)

That was the second Animation I did in Pov. I used Window clip art turned
into height fields for the horsed. A ducky, a horsy a bunny etc. it was for

Cool! I'd love to see it some time.

Ok, 'sinusoidal displacement' produced a fascinating 2 hours of Googling
with some great results (loads of PDF files there too), but, I do know what
you mean. ;)

And that's it? That'll make my horse go up and down whilst rotating? I
imagined some longer code... Thanks Ben, will give it a try when I'm fully
modeled-up for the scene.

Actually no, that's not it. You need to multiply the last line (rotate
y*some_num4) by the clock too, to make the horse move in circles.

It looked right when I came in last night from the pub :-)
Actually I was going to say to Steve that he does not need to render a full
circle. Because of the inherent symmetry of a carousel you just need to render a
fraction. If there are 12 horses in the outer row then 30 degrees is all you
need to do. The way I constructed mine was in sections by groups then the groups
were referenced. So it was the groups that rotated around the y axis and the
horses translated in the y axis.

Stephen

So would I but it was two laptops, eight years and several system crashes ago.
I probably have it on an Omega zip drive somewhere in storage but when I could
get to it I don't know :-(
My first animation was a Newton's cradle made out of Red Stripe bottles hanging
over Jamaica. I was working at Red Stripe in Kingston at the time. That's lost
too, more's the pity.

Stephen
