{{cquote|That would require a change in current fg architecture to use a CompositeViewer instead of a single Viewer, but we're contemplating that anyway.<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg17263.html|title=<nowiki>Re: [Flightgear-devel] Cockpit displays (rendering, modelling)</nowiki>|author=Tim Moore|date=Mon, 04 Aug 2008 02:43:52 -0700}}</ref>|Tim Moore}} | |||
{{cquote|Open Scene Graph supports a CompositeViewer object that supports rendering from several widely separated viewpoints, complete with | |||
support for multiple terrain pager threads. We could move to CompositeViewer and support simultaneous views from e.g., the tower, AI | |||
models, drones, etc.<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg17001.html|title=<nowiki>[Flightgear-devel] RFC: changes to views and cameras</nowiki>|author=Tim Moore|date=Thu, 26 Jun 2008 03:53:05 -0700}}</ref>|Tim Moore}} | |||
{{cquote|FG only supports one view position at a time, right? Multiple view positions (e.g. one screen for the tower view and a second screen for | |||
the plane) would complicate a "locked to cache" flag quite a lot...<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg28864.html|title=<nowiki>Re: [Flightgear-devel] Disappearing scenery</nowiki>|author=ThorstenB|date=Sun, 19 Sep 2010 07:41:13 -0700}}</ref>|ThorstenB}} | |||
{{cquote|Yes, and that's not really supported by the current architecture, neither by the tile cache nor by osgViewer::Viewer. We would need to move to a | |||
CompositeViewer model, which supports several scene graphs, and rely completely on the osg database paging machinery.<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg28869.html|title=<nowiki>Re: [Flightgear-devel] Disappearing scenery</nowiki>|author=Tim Moore|date=Sun, 19 Sep 2010 11:39:32 -0700}}</ref>|Tim Moore}} | |||
