Well we should avoid direct OpenGL calls like the sgEnvironment currently
does.
There is already preciptation code available in osg. So may be we have correct
rain really fast. The lighting cannot be that hard ...
Great to hear that I have helping hands!!!
For the direct OpenGL calls:
I plan to use Producer on the longer term. Using that we can easily build high
performance multi view installs with a multicore machine. That is there is
builtin support for multithreading in Producer. But that requires having
everything that is rendered in the scenegraph.
There is a great article about producer and the multi view technology on the
osg page. I just do not find it today morning.
I hope to put together some documentation and some links how to write code for
osg.

Ok.
