{{cquote|this also raises the question of reproducible clouds. If we have | |||
multiple independent viewers in the future, we need to draw the same clouds on | |||
each with a bare minimum of communication. So, what is needed to generate the | |||
exactly same cloud. May be an initial seed for the random number generator, a | |||
position and a size? We may need to identify such a set of parameters and may | |||
be we should have a peudo loader for osg producing this kind of clouds from | |||
these parameters. The you would be able to load and use these clouds from | |||
fgviewer and see isolated statistics about the draw/cull whatever steps. This | |||
might also help in understanding what is going on.<ref>{{cite web |url=http://www.mail-archive.com/flightgear-devel@lists.sourceforge.net/msg35147.html|title=<nowiki>Re: [Flightgear-devel] Trying to get more performance out of the 3D clouds!</nowiki>|author=Mathias Fröhlich|date=Wed, 07 Dec 2011 22:16:45 -0800}}</ref>|Mathias Fröhlich}} | |||
