only a standard projector is needed. for most of the videos i've seen use HD projectors but all the mapping is done in the software.

yeah. you just need to match the exact projector position (and lens data) in your modeling software and match "CAD World" and "Real World" and it should work.

Still. There's a couple things they did to make it look so good. They put an ND filter over the projector to cut down on the light spill, and stuck with mostly primary, highly saturated colors to make the dynamic contrast pop. The system contrast is probably really high, like 20:1 or something. The physical objects "screen" gain also has to be pretty low. .15 or .2 at least.

It's really well done, and I've seen dozens of these surface-projected systems.

Oooh, purty! I want a screen saver of that.

It's the same technique they use for large scale building video projection.

I wonder... There are some artifacts in the coloured-lines demo; it seems to interpret the edges of shadows as the edges of objects. Maybe they actually estimated the 3d data from the white scanning line shown first?

Ha! All the time I was watching it I just thought it was a completely computer generated image with a shaky-cam effect added to enhance the realism. After reading the comments I had to go back and watch it again to appreciate how cool an effect it really is.
