outside visuals question

Post by bgaviator2 »

Hopefully sometime in my lifetime I'll be able to build one of these sims. I've tried searching for threads pertaining to the outside visuals, but it is frustrating trying to search through hundreds of threads. I'll most likely be using the pre-manufactured FDS cockpit shells and parts....I'd like to do the 737NG sim. When it comes to outside visuals, what do most people elect to do to get the wrap around visuals? Wouldn't you really need 3 different projectors? One for the forward view, and then 2 for each left and right view? Is there a way to use LCD televisions for the displays, or is projection the way to go? I also saw the Project 727 web site, and it looks like they used a bedsheet at first, and then plexi glass with a paint material to throw the image. But it doesn't look like these guys had a left/right view with this method. Just looking for what the most common practice is to achieve the best visuals? Thanks.

You should take a look at this page, which in my opinion has the best visual system available for reasonable amount of money :)

Ok, so I saw how these guys did it....it looks like they used a fabric stretched over the cockpit, right? But they also had 3 projectors? It seems like they just used the forward view in FS, but used one of those triple-head units to split the image amongst three projectors.....but is this really realistic? Wouldn't you want the two side projectors displaying the side, or angle view in FS instead of just a wrapped around forward view?

I think you need to read the website in more detail, as they are showing 5 views of FS, not just the forward view.

looks like they used a white fabric screen to encase all the windows....but their web site only mentioned 3 projectors.

Not fabric... 3 screens about 1.5m from the cockpit windows.

We're just about to change to 3 ultra-short throw projectors and to all front-projection ... no more curved mirrors! :)

Yes, three projectors but 5 views. Make sure you read the site very carefully and you will see how they did it. It's brilliant.

Hey Nic,

I am currently trying to set my external visuals using the information on your web site. I do have a few of questions though:

1) You mentioned “You can edit your situation file (.flt) later to adjust the
window dimensions and their status outside of FS. We were able to
make the 6th window (the unwanted one) to stay unmaximised and
very small (20x20 pixels) by editing the file”

Which file items need to be edited? Are they under the “WINDOW”
0,1,2 etc headings, and are the ones labeled ScreenUniCoords=.
If this is the case there are (4) sets of numbers, 4 digits each, so
which ones need to be edited? Can you tell me what does each one
represents?

This I assume tells me you used this editing to set all (5) undocked
windows to 614 x 768 pixels?


2) In order to get the windows to blend at all, the window height is
considerably less than my screen or even the monitor height. I have
set my three projectors to an aspect ratio of 16:9 is this correct or
should I be using 4:3 aspect ratio?

Or to better ask this question, how would I be able to get my
projection floor to ceiling like yours ?

I am using (3) 80” screens, the projectors ( front projection) have a
throw ratio of .5 which places them about 40” from the screens. I am
not concerned of getting the images all the way to the floor but would
like to fill the flight deck windows and of course have the scenery
line up perfectly.

As I have scene from your web site, this forum and the MY cockpit forum your project is a real inspiration to all us builders and many thanks for sharing it with us.

Much Success

Where I am right now i cant see my files (and sorry - we dont distribute them) but the screen unicoords are what you are after. Four values are x,y position and x,y size... I just cant remember which is which right now (6am here :) ) But if you adjust one at a time you'll pick it up real quick.

Pixel window sizes sound about right

Aspect ratio of projectors shouldnt matter, but try 4:3 at first

Window heights - strange - should be all ok at full height, but experiment with zoom factors and see if that helps to get your vertical size

Maybe I'm just so unskilled at building things, or I'm going blind....but I am not really seeing details of how this display was done. I've gone through every page on the build diary.

Ahhh, I'm seeing it now. Never noticed the tiny blue links at the top of the page before on the design details.

I get it now! I guess knowing where to look on the page helps. Very informative information. Sounds fairly easy, especially if you had a ton of space to work with.

Hi Nic

I spent quite some time yesterday following your recomendations. Your are right it does take some time and except for some small tweaking I HAVE GOT IT :lol:

Many thanks for your brilliant work and sharing this info and insights with us all.

Enjoy your short throw projectors they are really awsome.
