Hi all:

I'm looking for a solution to make an installation in which we want to make a cylinder screen where to project 360º panorama images.
I guess there are some "analog" and digital solutions, using two or more projectors, a kind of lenses and some soft or hardware sync mechanism using two ore more signals. But I have no idea which brand can supply this solution.
Maybe some of you know a way to achieve this.
I will listen to any idea.

Thanks.

To do this, cheaply, is likely in the $75,000 or so range.

Check www.immersivedisplayinc.com for some contact information. It is extremely difficult and costly to do this as it goes entirely against every way that things are shot and put together in the industry.

Really??!!

Well, we don't have such budget to do it.
I'm thinking in a cylinder not a sphere. There have been lots of show stages with this kind of solution. I wonder a common projector and a kind of fresnel lens correcting the geometry may work. In this case I imagine a setup with 2 projectors with this lens rising both 180º...

Another idea?

I have seen almost nothing of this nature in projection other than really cruddy setups where people shine onto a cylinder and there is lots of distortion and things just look horrendous the further from center of focus that you get.

Anytime I get to an event which offers unique projecting options I check them out, and the reality is that they are all extremely expensive and if you ever see a commercial display of this nature, it may not be unrealistic to find out that they spent $100,000 or more to get the setup they wanted.

Keep in mind that with 2.35:1 setups, that's just widening a normal 16:9 home theater projector by 33% properly, requires a lens which typically costs about $5,000 for a good lens. The cheap lens costs about $2,000.

For a full 180 degree fisheye you are going to have incredible optical distortion which isn't going to be easily compensated for and even a cheap 180 fisheye lens for a typical projector sized lens will typically run in the several thousand dollar range.

If you really want to get something even halfway close for a lower price, then I would be looking at a 4 or 8 headed computer card and use 4-8 $2,000 projectors to accomplish things. I would expect that you can get some decent results for under $20,000 or so.

If you think $20K is beyond your budget I am really not going to be of any help at all as this is what I would consider a low-cost, blunt force solution and you may be asking for something which is incredibly unrealistic.

If you do find something which works as a solution, please, share with the forum.
