Currently, all placements are within the main FlightGear window, however there's been talk about providing support for additional Canvas placements, such as e.g. osgviewer placements to help generalize our [[Howto:Configure camera view windows|Window Management]] routines, so that a canvas can be rendered inside a dedicated OS window: | Currently, all placements are within the main FlightGear window, however there's been talk about providing support for additional Canvas placements, such as e.g. osgviewer placements to help generalize our [[Howto:Configure camera view windows|Window Management]] routines, so that a canvas can be rendered inside a dedicated OS window: | ||
Would it be possible to place the new "view" into a window instead of having a dedicated view? That would allow you to have an instrument panel with a blank cut-out that could hold this newscam/FLIR window.<ref>{{cite web | |||

Several responded that you can have a view, or multiple camera offsets, shared across many screen. I have tried this and it works well on the mac. But what I want to do is have two windows, one with a custom view i have defined, and another window with the cockpit view. Ill keep digging, but i read somewhere that this particular thing is hard.... because there is only one view manager instance, and it can only allow multiple camera offsets...<ref>{{cite web | |||

We can define arbitrary areas of the screen and draw any view perspective into them. However, I think all the views need to be from the same eye point. (i.e. you can't have a cockpit view in one window and a chase view in another?) However, the capability we do have is very nice for supporting devices like the Matrox Triple Head 2 Go box, or Twin View, or any "spanning" desktop system. And we have the ability to extend this to multiple displays. There is an AMD/ATI demo movie floating around on youtube that shows FlightGear running on 8 monitors using 4 dual-headed video cards.<ref>{{cite web | |||
