I bought a hologram projector recently. So far I have only loaded into
it a simple model of the earth, but once I get to know better the
software that came with it, I might load more interesting models into
it. :)

I filmed it with my digital camera. Unfortunately the quality is very
poor, but you get the idea...

Wow! Amazing!

Go on then, tell us how you did it. How did you track the movement of the
camera?

I'm going to take a guess....

The whole hologram projector including the base is ray-traced?
So maybe there was some sort of X or marking on the table underneath the
projector that you could track the camera by?

And by the way, that's the coolest POV animation I've ever seen.

Rune, you've got too much time on your hands. :-)

Seriously, I guess you went about and just tracked
the camera frame by frame (maybe not every frame,
but enough to interpolate), and then placed your
holographic projector there. Neat job!

Regards,
Tim

How *exactly* do you match the cam motions up ?

Hahahaha.... Rune's waiting for the questions to accumulate..... and then
he's going to tell something that makes people say "ooowww.... I could have
thought of that, but I didn't"

I'm guessing that the camera jiggle was added later. Smooth filming, create
a 3D globe that has the same basic rotation, overlay it on the film and then
jiggle the whole thing for a shaky camera effect which would cover up some
of the defects that would be seen in an overlay with smooth camera work.

That's a very good technique (I know they often do it in movies), but then how
could he move the camera smoothly?
