i agree with everyone here pretty dam good but what is the screen in the backgound I dont get that one?

Dave you and I would love a setup like that ay! oh to work to work more money hehe :)

I was also wondering if you could use a curved screen like the real sims to get the same effect?

If i'm looking at the same thing you are, the screen in the background is actually the mirror bouncing the image back onto the screen. Utilizing the mirrors saved my 5' of throw space.

I wanted a curved screen, the problem with that set up is you need to add in some very expensive equipment to "bend" the image around the curve. Without it, the only clear image would be on the part of the screen that is perpendicular to the projector, the rest of the image would be distorted.

Guys ,
Let me help you out abit, John's fantastic setup is actually very simple in design. He took 3 Plexiglass/Lexan panels and joined them together, before doing this he sprayed them with a product called Goo (You can buy it on Ebay). This product allows you to rear project through it as if it were a rear projection screen. Now he took 3 projectors and placed them below the screen level , if you look in the picture in the foreground, you will see one of the projectors. This beam now hits a mirror sitting on a saw horse type stand and aimed at the back of the screen. The mirror as stated by John is merely to cut the throw distance down in actual feet by fooling the projector into thinking its 2X as far from the screen than it really is. So basically the projector shoots an image away from the screen onto a mirror and bounces it back to the screen panels of painted lexan he has carefully placed and aligned in a wooden frame, additionally he seals the seam so it wont be noticed too much by the eye. His 3 projectors are a joined image through Matrox2go triple head system and voila a masterpiece of visual aviation is born. Hope this helps.

very good tim but which side of the screen do you spray or does it not matter?

Thanks Tim, couldn't have said it better myself. :D

You spray the side that the image is projected onto.

Anytime my friend,
By the way guys I'm taking Johns setup 1 step further. As he originally took my mirror idea further, Ive moved forward with his, the beauty of this hobby is always improve it through constant change and information input from many sources.What I am doing is taking several pieces of 3/16 lexan a little larger than the window frame size of my deck and coating them with goo. Then placing the projectors in front of the sim bouncing off a mirror same as you see John doing. However the difference is my panels are screwed right to the window frames thus creating the total immersion illusion. This way you are forced to only see out the window as in real life. These are just my thoughts. High 5^ goes out to John for his initial groundwork into this ideaology.

I've been thinking to do the same Tim, so interested in how you go. We demand pics! :D

I won't be able to do this for a while coz the sim is in a narrow space for the time being.

Dave,

I think they mean the side that faces the projector...ie. back of Plexi if its rear projected...
You spray the side that the image is projected onto.

Tim,

This is exactly what I have had in mind for a couple of years now- putting the 'screen' where the actual windows are. Back when I was still on the 737 prject, this was perfect, but now with a Lear 45 being worked on, the dog-on windscreen on those are cast acrylic or somthing and round. DARN! Anyhow, the brilliant guy down in South America with the real 727 with first class section has done this same thing by draping sheets over the front of the flight deck and also the passenger windows and it looks great. I look forward to your results.

Tim,

I am really curious about whether this is the best option. It sounds really, really good, but I wonder if you are going to lose some of the depth perception by doing that. You will no longer need to focus your eyes at a distance to see the projected image and if I recall correctly, Fresnel lenses work by changing your focus point as well so that it looks like the image is much further away.

The other disadvantage that I see in your new method is that you can never 'lean over' to see a bit more of the outside view like you would do in a real plane if you wanted to see below or above the window frame. What you see is what you get in your case and I think this will detract rather than enhance the realism.

Having said that, I can't wait to hear from your personal experience. I really like your idea and I hope that my concerns are unfounded. So, anxiously waiting for your report :-)

Maurice
