I would think you would need something that would brighten the image as you move toward the outer edges, since the light there has to spread over more area. Do you notice it's darker there?on line abortion pill misoprostol dose abortion medical abortion pill online

Yes, even if the dome itself isn't patentable, the mehcanims to make, install, setup etc may be.

Creating a geometry altering algorythm might also be patentable - at least in the US.

You could also do this at the "raster" level - by building a real-time application that takes a snapshot of the screen, separates each pixel, then applies a custom distortion mask to it to create corrections for geometry and finally anti-aliases it.

A good algorythm could take a standard resolution of, say, 1024 x 768 and blow it up to something a high resolution projector can handle (eg, 1920 x 1080) and then adjust the resolution for geometry in projection so that the centre contains more detail than the fringes and so when projected it all looks normal.

That could be an alternate way to do it - something like FRAPS does... Except re-encoding it with altered geometry.

I recall a similar technology on Youtube ( or maybe it was slashdot.org ) that could project from any angle onto a screen and adjust the geometry of the picture so it looked normal.. Like a super-keystone correction algorythm. Even worked on curved surfaces if I remember correctly and it self-adjusted automatically. It used a camera with a projector to self-calibrate.

I remember they would put a white model car down and it would use the projector to overlay paint bitmaps on it no matter the angle it was on...

Anyway, a useful market for your application, in sample quantities, might be game marketting companies who do tech shows... They are always looking for a useful gimmick to draw in the crowds to their booth so that they can peddle their wares... Something like you did would be very useful for that, and would showcase your tech while making you some sales.

Even an incomplete/imperfect technology is useful simply because it's different.

In theory, that if jDome becomes really popular, and developers start optimizing games for it, it seems like jDome could even expand to consoles, too. I can see it now: Super Mario whatever for the next Nintendo system:

Main Menu
-Options
--Screen Settings
---Widescreen, standard, or jDome?

hehe, that'd be awesome.

Gizmondo estimates a price somewhere between $100-$150, true? If so, I think it'll really take off. Being able to play a game in jDome's pseudo-VR environment at an affordable price would be awesome, and it definitely is a more affordable version of Namco's prototype arcade cabinet that was similar to jDome.

The difference between jDome and this prototype was that the prototype projected the image through fisheye lens, rather than with jDome's method.

Sounds really cool, and at an affordable price, I think you're on the game grid to success.

I was wondering though, how would a game like Defcon run with jDome? Defcon is essentially 2-D, and I was wondering how a game like that or Super Mario Brothers or the like would run with jDome. Would changing the FOV be neccesary for such games?

Nice video!

I'm still wondering, though, would any source code modification be required for games that are played from a two-dimensional perspective - such as the one I provided a link to? Here's a screenshot:



The game is not played from a three-dimensional perspective, rather it's played as if you are looking at a big animated map of the world. If you've ever seen the movie Wargames with Matthew Broderick, then you can tell it's like the big map screen of the world in NORAD.

FlexibleFront wrote (regarding NAMCO's beta Starblade game)Well, do you know why it was cancelled after public testing?

Although NAMCO never officially specified why it was dropped, I'm assuming that it was because of the high cost of the cabinet. The original Starblade game had that problem, too. The seat would vibrate whenever you were hit, and strobe lights would blind you. Whenever you hit an enemy, a red LED light would light up on the flight yoke on the cabinet (which was used for aiming and shooting). But because of all of these features, the cabinet was very expensive and heavy, a problem I assume was a leading factor in the failure of Namco's prototype. I sincerley hope that jDome doesn't face the same problems.

FlexibleFront, that looks awesome, I noticed while playing battlefield 2 how people were able to see around corners simply because they had widescreen, and thus capable of seeing and shooting around someone viewing the game in 4:3. This makes your invention very exciting for gameplay, simply because most people don't even know their capability in such an environment, 180 degrees. very fun.

I have one question. Could you make optical illusions using multilayers of fiber and gas/fog, or special lenses inside the materials to enhance it? (such as a second projection method intermittently enhancing FOV 3D).

I'm just wondering if that thing is HiDef, and if you could make it HD?(mostly)

Hi there - long time no see!

Really cool news about the TR2N movie!
