A friend of mine supervised a girl/young woman with her
graduation work. She is designing and making a system for
EMC (electro magnetic compatibility) measurements
(more or less checking if a device does not exceed the
interference limits) using 3 big circular antennae
(in fact 1.5 m across).
She used to dance at dancing contests, so this clip was
rather unavoidable, I guess.
Not finished yet, I want to add het printed circuit
board of the amplifier as a floor element.

Good creativity, from that to hula-hooping.

It plays in slow motion here in OE so I opened it into Jasc's Animation Shop
to see if the frame rate needed a change. It didn't really, at 25 fps,
however I tried 33 fps (or 3/100 fps) and it seemed closer to reality to me.

Not sure if it's just my own imagination but the hoops on the arms actually
look as though gravity is affecting them, as if sliding or dropping a little
when they reach their apex. Mostly the forward-pointing arm where it looks
like the hoop loses contact with the arm at that moment. If you worked that
into it I commend you on your efforts.

Nicely done animation of a human model and interacting objects.

I also noticed that there is a difference in speed with IE and Netscape
compared to what I speciefied in Animation shop (that was what I used
for generating the animation from the POV frames).
I am not sure if that is what you mean though, the 'real' speed is
probably between 25 and 33 fps. Only that should be faster in the
downwards movement and slower when going up. I totally forgot
to take that into account, must be my physics background.

I will look very carefully when making the final version. Actually
I discovered a couple of days ago that the horizontal loop is going the
wrong way, so I have to remake the whole thing anyway.
(the horizontal loop should 'wobble' a bit because of gravity
but I will not do that, because it would than not be orthogonal
to the other two.)

thanx, but it was not much intelligent work for me. I planned to
do it more complicated, cutting the plane of movement with the
model and computing the intersection points etc.), but in the
end I used poser for positioning the hoops. I had to postprocess
the includefiles a bit, because there are some nasty things in
it (especially the eyes) and I have more control over texture
in pov, so I used only one include file for the textures.
