Hi, I�m an artist/designer who�s working on an installation project, I�m planning on creating a projected 3D animation, and was guessing if it could be done with holography. Does anyone have any experience of this? If you have any info about hologram manufacturers, and how much it could cost, please let me know. Thanks.

Are you saying that you have a 3d animation that you want to have projected as a 2d image? I've seen that done a few ways. Or are you saying that you want a true 3d hologram? As far as I know, that's not currently possible.

You could use holograms instead of a video projector, which one is better depends on the kind of image you want to make of course (I�d say holograms are better if you�re looking for a good 3D effect). There�s a list of hologram manufacturers at this site: http://www.ihma.org/member_list.php

Good luck � Be sure to let us know how it goes�

In principle you could get a 3d effect by applying a trick that uses interlacing:

Render out three viewpoints of your animation, and interlace each frame so that you get an image comprised of vertical strips taken from each of the three frames, in a 123123123 pattern. Then print out a mask for it on a film, with a pattern of 2 units black, one transparent, and place in front of the image at some distance. This should, if done right, give the viewer a different image depending on where they are standing. Only three different views though, so it's pretty crude, and I'd expect it would require the viewer to be at a specific distance to see it optimally, which would depend on the distance the mask is from the display, and which in turn would dictate the width of the mask stripes.

This would still just give you a thing-in-a-box effect, though, definitely nothing coming out into the space beyond the display.

May be of interest to you.

I've seen the fogscreen in action, although with ambient light and in a large space with air flowing all around, but the image clarity didn't seem that great to me. Not great for anything with small details.
