Pictures of my curved screen setup

Chris, that looks really good. I assume they make the displays to suit each customers requirements. What's the company?

The company I was working with when I see it was www.sg4.co.uk in Southend but they seem to be available everywhere if you google 'curved pop up stand'.

Sign writing is an expensive industry and they are milking the prices for these so I am looking for a cheap supplier now

They seem to be giving them away on ebay http://cgi.ebay.co.uk/Pop-Up-Exhibit...item4cf177a7b2

That one is just down the road from me but I dont have £125

I have one Sean if you want to see one .....the usual four x three set up is probably not wide enough for a sim but you can, I believe get, wider pop ups.
Not seen them as cheap as £125.00?? they start from around £900.00

Maybe show me on Saturday.

Just the stand (3x4) can be bought for as little as £90 new from direct suppliers but without a screen so dont be shelling out large wods of cash for this setup. I am buying a frame next week and will get a price for 3x4 screen sooner

Hi ,
can anyone tell me what`s the minium radius for a crispy 180 degree angle view ,
for a 2 or 3 shortthrow beamer setup please.
I have only a smal room for my setup of 2,3meters wide, height 2,2 meters and 3,5 meter long.
And because I have parked a real cessna cockpit ,I have only a total radius of about 2.3meter.
will that be sufficient to set it up with sol7 or others?
for now I have a 3 monitor setup ,but somehow I`m missing something

I might have missed it in the past four pages, but how do you plan to have just two front views?

FS9/X displays front, front left, front right, left, right, etc. Since these are quarter views, how do you plan to to display just two? Are you doing front and front left? What am I missing?

You can use 2 projectors (or monitors) with 1 single front view that would span the distance of the 2 displays and be centered where the images meet.

This is what I mean by keeping to the angle of the lense. Short throw projectors allow tighter curves due to having a more bulbous lense.



It seems to be a general rule of thumb that does not seem to get much mention in the projection threads and makes sense from a theoretical point of view or whichever way you look at it. Nthusim is great at doing what it does but the rules of how light travels and bounces off the screen still need to be adhered to.

My pit will start with only a slightly curved single projection screen so will test this theory out asap and post results in the relevant thread.

Hello,

I think that it is not mentioned a lot because it is not that simple, normaly the projector lens is concave not convex or a mix of a concave and convex lens, it's made to project a flat image, not the one you have on that diagram, if that was the case the projected image would be a circle made by a projecting cone, a projector actualy throws out a sort of a inverted piramid... What you mention is to do with zoom factors just like in cameras where the lens is used to do the oposite, project a image from a spherical lens on to a flat sensor.

The short throw projectors have a wider lens to correct the fact that it is placed much closer to the image source, if you continue the two lines in your scheme they intersect, the closer the lens is to the intersection the more apart they can become, the wider the screen area.



"A concave lens is exactly the opposite with the outer surfaces curving inward, so it makes parallel light rays curve outward or diverge. That's why concave lenses are sometimes called diverging lenses.

Concave lenses are used in things like TV projectors to make light rays spread out into the distance."

Hope it helps.
