4D Holograms

A team of medical researchers up at the University of Calgary in Alberta has spent the last six years working on a remarkable "4D" hologram system called CAVEman. (Tech)

Liars... there is nothing 4D about this... still quite impressive

um...
Are you certain that you know what 4D really is?

I would suggest you, and everyone into graphics and gaming, join ACM and then view Siggraph articles on 4D...

In the 3D realm, like this one, 4D represents viewing/navigating through space AND time. Basically EVERY attribute is an expression based object, and not scripted.

In reality, you can use any attribute in the 4th dimension. This is what multi variable calculus is about. These are your hypercubes, folding knots etc...

Remember 4D has nothing to do with colored eye glasses, thats 3D. Its the glasses that allow of the illusion of 3D. Every 3D game you have ever played, its really just 3D, presented in 2D on you screen.

Here is a simple example of 4D, being represented in 3D, with a 2D graphics projection on top:

Do you think the PS3
is the supercomputer behind this? It is a 4D capable after all.

This is sarcasm, btw, for those that can't figure that out for themselves.

I believe there have been examples of 4D on PS3 already. Not in any games yet released, but remember the 4th dimension is time, so any textures or polygonal forms can be procedurally generated as a function of time. There were some examples I saw (some decaying bathroom scenes - unscripted, procedurally generated) but I can't remember if they were running on PC or PS3. If they weren't running on PS3 I think it was implied that they could or something to that effect.

edit: tfur knows what he/she's talking about.

I'll wait until they showcase the 5D stuff..
Because that must be so much better than anything that's 4D in comparison to 3D.

and by the way...
I have no idea about what this system is running... but after seeing a few silly posts...

Yes, the SPU's on the cell processor do perform matrix calculations incredibly well, as that is basically what they are designed to do...

Very Nice
Remember seeing this in the news a few weeks ago, very impressive. GO U OF C!
