Per Johnny 02-11-09, 03:27 PM I am alomost sure that it is identical to the room where my first 909 came from. It may be the exact room, I dont remember for sure, I was more focused to get the 909 with me. :D THE_COW_IS_OK 02-11-09, 03:38 PM i guess what i don't understand is how can 9 light path's cross-over each other without interfering? Light wave just slike sound wave surimpose on intersection and never affect each others. nidi 02-11-09, 05:14 PM I am alomost sure that it is identical to the room where my first 909 came from.

Michael donaldk 02-11-09, 07:12 PM Guess it is in France, as it is posted on the French forum, picture looks familliar, probably seen it a long time ago on one of the French Barco integrators' website, when I was checking them out when Spotmatic was looking to get his 909. mp20748 02-11-09, 07:15 PM i guess what i don't understand is how can 9 light path's cross-over each other without interfering? I service a very similar setup that also has three 909's in the same configuration. The screen in my system is 20' wide, but it's a curved screen. It's also 10' tall. I've wondered the same thing when I first saw a setup like this, but for some reason, they don't bother each other at all. The only thing about these type of setups is that it's very important to mount the projectors mounted on a RIG (solid metal frame) that suspends from the ceiling on cables. Alan Gouger 02-11-09, 07:18 PM Man I bet this looks so good in person. Sitting that close is what its all about. You can only get away with that using CRT. All you guys doing a simple 2 way blend youve been out classed. Time for you to rip up your system and start over again:) Tim in Phoenix 02-11-09, 07:50 PM Man I bet this looks so good in person.

Time for you to rip up your system and start over again:) Guys! This would not be practical for home use; three projectors would have near a 3:1 aspect ratio, so what good is that? . mrowley 02-11-09, 07:54 PM How could you watch standard video on a set-up like this? Each PJ would project three separate full images of the movie. Right? - or not mp20748 02-11-09, 08:08 PM How could you watch standard video on a set-up like this? Each PJ would project three separate full images of the movie. Right? - or not The 909's had a BLEND option, that made them upgradable for multi-projector blending. The blend option is called "SEMU" Depending on the blend configuration, each 909 with SEMU can be made to blend at top/bottom/left right. So they can be used in stack blending, where multiple 909's images can also be edge matched on top as well as the sides. SEMU is a neat option for the 909, but it's the worse bland system out there. If blending using this system, you'll also need the image split before each projector. Blending works better when there's no more than two projectors involved.. Per Johnny 02-11-09, 08:51 PM Oil company ? Michael Yes, you are correct. Here in Norway the 909 has been used in both oil and ship simulators, and one company build one facility for renting to several industries, that one didnt do very well, all the equipment was sold and shipped to Australia, that is what I was told. That installation was also very similiar to the one in the pictures. Mark_A_W 02-11-09, 10:16 PM all the equipment was sold and shipped to Australia, Really?? Well, well, well. That's good to know. ;) Mark_A_W 02-11-09, 10:18 PM I've wondered the same thing when I first saw a setup like this, but for some reason, they don't bother each other at all. Umm, the reason would be PHYSICS :D ChrisWiggles 02-11-09, 11:45 PM i guess what i don't understand is how can 9 light path's cross-over each other without interfering? Is it April 1st where you are? You're a couple months off... :D psilvest 02-12-09, 04:36 PM i guess what i don't understand is how can 9 light path's cross-over each other without interfering? Light wave just slike sound wave surimpose on intersection and never affect each others. Actually light waves can affect each other (optical interference) but only if they are from a coherent source, e.g. from a laser. Light from a CRT is completely incoherent and there cannot be any interference (but beam intensities still add up, as it happens for instance in the blend zone on the screen - no energy is lost..). Interference can happen also with sound or any kind of wave (otherwise your noise-cancellation headphones would not work..). Ciao, Pier Wrager 02-12-09, 06:28 PM Even though I sold my CRT years ago, I still love to come to this area...some of smartest people the world over! Wow!

Interference can happen also with sound or any kind of wave (otherwise your noise-cancellation headphones would not work..). Ciao, Pier This doesn't mean they are affecting each others. The reason why noise is cancelled is because a wave is superimposed with a similar wave with opposite phase. Its as simple as generating a -1 to add to a +1 and get 0. Once out of the intersection again, u ll get back 2 waves exactly similar to the one you had before intersection. Chuchuf 02-13-09, 06:53 PM The real question is, is the light acting as a wave or a particle? Guess it depend on who is looking at it........lol Have any of you ever seem the experiment that was done when light was put through a Bose Einstien Condensate (BEC)? "In February 1999, a team of researchers from Harvard University led by Lene Vestergaard Hau used the BEC to slow light—which normally travels at 186,000 miles per second—to just 38 miles per hour by shining a laser light through the condensate. In 2001, Hau's team announced that it had briefly brought a light beam to a complete stop." And what is really weird is that when the light leaves the BEC, it returns to normal..... Terry Curt Palme 02-13-09, 09:25 PM You just had to bring Bose into it, didn't ya? There goes the neighborhood! macgyver655 02-13-09, 10:35 PM The real question is, is the light acting as a wave or a particle?

Terry I saw that experiment on tv a few months ago. There was something in particular they were trying to accomplish but I dont remember what it was. It was pretty cool though. MikeEby 02-13-09, 11:00 PM From Ghostbusters. Dr. Egon Spengler: There's something very important I forgot to tell you. Dr. Peter Venkman: What? Dr. Egon Spengler: Don't cross the streams. Dr. Peter Venkman: Why? Dr. Egon Spengler: It would be bad. Dr. Peter Venkman: I'm a little fuzzy on the whole "good/bad" thing here. What do you mean, "bad"? Dr. Egon Spengler: Try to imagine all life as you know it stopping instantaneously and every molecule in your body exploding at the speed of light. Dr. Ray Stantz: Total protonic reversal! Dr. Peter Venkman: That's bad. Okay. All right, important safety tip. Thanks, Egon. Mike macgyver655 02-13-09, 11:03 PM Here's some more info on that experiment: Another contender for the coldest spot is across Cambridge, in Lene Vestergaard Hau's lab at Harvard. Her personal best is a few millionths of a degree F above absolute zero, close to Ketterle's, which she, too, reached while creating BECs. "We make BECs every day now," she says as we go down a stairwell to a lab packed with equipment. A billiards-table-size platform at the center of the room looks like a maze constructed of tiny oval mirrors and pencil-lead-thin laser beams. Harnessing BECs, Hau and her co-workers have done something that might seem impossible: they have slowed light to a virtual standstill. The speed of light, as we've all heard, is a constant: 186,171 miles per second in a vacuum. But it is different in the real world, outside a vacuum; for instance, light not only bends but also slows ever so slightly when it passes through glass or water. Still, that's nothing compared with what happens when Hau shines a laser beam of light into a BEC: it's like hurling a baseball into a pillow. "First, we got the speed down to that of a bicycle," Hau says. "Now it's at a crawl, and we can actually stop it楊eep light bottled up entirely inside the BEC, look at it, play with it and then release it when we're ready." She is able to manipulate light this way because the density and the temperature of the BEC slows pulses of light down. (She recently took the experiments a step further, stopping a pulse in one BEC, converting it into electrical energy, transferring it to another BEC, then releasing it and sending it on its way again.) Hau uses BECs to discover more about the nature of light and how to use "slow light"葉hat is, light trapped in BECs葉o improve the processing speed of computers and provide new ways to store information.

Whoa. The show you saw Macgyver was the Nova about The Race to Absolute Zero. Terry Chuchuf 02-14-09, 09:19 AM You just had to bring Bose into it, didn't ya? There goes the neighborhood! See they really are GREAT speakers. We just didn't understand that they work best at -273 degK.........lol Terry Art Sonneborn 02-14-09, 11:56 AM Guys!

See my creation Welcome to the forum Very impressive can you share some details.How many projectors are you using. Are they digital or CRT. Would love to see more pictures. What are you using to perform the blend. Are you just splitting the image or are you also using a soft blend as well. Keep us posted. Its rare we get any blend pictures, keep them coming.

Plenty of people here here that are running blends. Lets get some pictures going even if the system is not finished.
