It's been a while since I've done any animation, so here's a quick mechsim
animation of a coin.  Not too original obviously, but oh well.  It's
cheating since it's not a rigid body - but it works for me.  The motion
blur is entirely withing the motion_blur{} syntax although it may have been
easier to just average frames.  If you rotate the camera one direction,
just move the scene the opposite direction.  Sounds simple at least...

now that looks realistic !  Took me 4 cycles to notice it wasn't filmed :)

easier? maybe, but the results will be less realistic, since motion_blur doesn't
clip colors, so bright parts will look better

there is another way with the latest megapov: camera_pigment (or something like
that).
First you put the moving objects into a motion_blur{} statement, and then add a
camera with a Screen_Plane (see screen.inc) with a texture of which the pigment
is an average of camera_pigment's, simulating the movement of the camera.

I think there's a demo-scene included with megapov that uses this camera motion
blur technique.

cu!

Mechism animation??? Isn't it a real recording?

It's very cool! Motion blur really makes it look real. I have to remember
today to download MegaPOV!
