Best width of projected image?

[orwell84]

Hello,

I am trying to determine how wide the outside projected image should be for a one projector setup. Because of the demands of the space I'm using, I will need to use rear pjoection to get a decent throw distance.

What is a good image size for a 737?

Thanks for the help.

Ok, I can make this question easier. The width of the room the simulator is in is 8', so the maximum width the image can be is 8'. Is 8' adequate? Is a smaller size like 6' ok? I'm just looking for a ballpark idea of how wide this thing should be.

Thanks for the help.

You need to figure out the view angle out of your windscreen so that the projected image is wider than the view angle.

Sit in your cockpit and look out the window. Have someone mark on the walls the edges of what you easily see from your normal seated position. Hopefully you cant see the whole wall and more from the pit.

There have been all sorts of discussions about this. Some people go to the bother of adjusting the overall projection to fit the actual scale of the real world objects in the exact configuration that a real pilot would see. It gets quite involved to do that. Can't remember whre I saw that stuff.... but I am sure someone will point it out to you eventualy.

From my point of view... if it fools me... it is good enough.

best,

ok I am still in the process of getting this idea built ,

but i thought it looks promising if you have a small space ,like i do if anyone else has tried this your oppinions would be great cheers hope it helps..

This seems to be a good solution for a small room

You can have a flat screen or a curved screen

Thanks,

That is a perfect, absolutely perfect solution. The dimensions you describe will work and it is a load off knowing that I can achieve this in the limited space that I have.

In spite of your detailed explanation I have one question. I think it's an easy one. here it is:

What is the brand and model of projector you are using? Is it a short throw, or just regular projector.

And again, many thanks

I will be using 1 hp vp6120 projector for this which is just a standard throw, if you measure from projector to the slightly curved mirror , i have one metre then back to the curved sintra or screen i have about 1 metre ,= 2 metre throw, but with the curve you can strech it a bit more, I have noticed that if you curve too much things like buildings get short & stumpy, just expierment. like i said i havnt fully set this up at the momment ,in the process of CNC building. Good luck, let us know how ya go..

If you have limited space for the outside visuals, then I really recommend the ultra short throw projectors. You can place the projector against the wall (or screen) and have a big image covering the windscreen.
I am using these types op projector, great resolution and brightness.
Even when having a big room, the advantage of this projector is that you can make a compact and stable setup.
Also with these projetors you don't have to go into rear projection, having to buy expensive screens or loose image quality using cheap material like bedsheet or so.

Thanks for the helpful replies.

Actually, I will probably go with the BenQ MP 522 ST. It's a short throw projector, but not an ultra short throw. I agree with you that an ST projector is a good idea because it allows more flexibility, even if I use a curved mirror. The more compact the setup, the better, for sure.

Thanks again.
