Prepar3D + curved screen + 4 projectors + 3 PCs - views problem

[voytik]

Hello all,

I have 240° curved screen, 4 short-throw projectors and 3 PCs running Prepar3D (first PC is a wideview server, while the other two are clients for rendering outside view, each running 2 projectors) and I have trouble setting up the views in Pr3D. I tried the windowmaker spreadsheet, but when setting up 4 windows, the views doesn't connect seamlessly. Especially when turning, the edge between window is creating weird movement in the picture which is not right. Is there a way to create seamless 240° picture with my setup?

Any suggestions would be appreciated!

When you say "weird movement", do you mean that when you bank the horizon line does not stay lined up at the vertical seams of the projectors? Also, did you tweak your zoom values too make sure that what you're using is correct. Windowmaker gives you the ballpark, but you have to tweak it to get everything just right.

Also, it sounds as if you're likely using the wrong camera choice in windowmaker. I am not able to look at mine currently, but you have to make sure that the camera is the right one; I cannot remember if it's a 2D view or 3D Virtual view value. However, it is a long string of numbers to read...

Finally, you did not mention which correction program you're using for the curved screen. Are you using Nthusim or another similar program? If not, then you're missing the most important part...you cannot correct for a curve screen projection setup without one of those programs.

Well the horizon change angle at each window boarder when flying up or down, that is the weird movement I am talking about. When I used zoom 1, I managed to get perfect window view alignment (one seamless picture in any condition), but the FOV was really small. Then I used the zoom of 0.55 from windowmaker and now it is not possible to create usable alignment, it is very clear, that it is composed of 4 windows and in the connection of each 2 windows, the horizon change the angle quite rapidly. But I guess that is just the way P3D treats views with different angle.

For curved screen correction I am using ImmersaView Warp, I set it up just fine. The problem is only in P3D.

Hi Voytik,

I am a user of Wideview and have been for some time now. I feel what you are trying to achieve will not work whilst using Wideview. As you kow, Wideview is only going to work correctly if you are producing one view per computer. Each view being equal to the angle of the projection and then with the correct zoom. What you are doing is producing two views per computer and only have the ability to control one of the views in the Wideview View setup configuration. If you were using 3 projectors and three clients, then this would be an easy task. The introduction of Window Maker, I think you will find is going to be your problem. As you have only two client computers and four projectors, it is a shame you could not have 4 client computers. You can however, use the Server for and outside view also as I do, providing it is up to the job and then you would only need one more computer. If you take away Wideview and use he Window Maker only, then it would depend on the ability of the computers as to how many window views they could handle.

Kind Regards

Bernie.

Hi Guys!

We are using Wideview with two client computers and three views (projectors). Two views on one computer works fine. Read the manual with patience, specially pages 40-41.

Hi Henri,

I must admit that I thought I had read the manual back to front a number of times, but as I do not use Wideview in this manner I will admit that I must have skimmed over the section regarding the use of the extra windows and the Dummy Aircraft. Do you get seamless views using this method?

Kind Regards

Hi Bernie,

Yes we do.

We had Prepar3D set up in multichannel with pixel perfect seamless views. Recently we switched to Wideview and were able to reproduce the exact same views as with P3D-MC.

Hi Henri,

Yes it was good that Luciano updated the software to work with Prepar3D.

Kind Regards
