[osg-users] OSG + sky

[Cole, Charles E. (LARC-B702)[GENEX SYSTEMS]]

Just some more suggestions for references ...

 

(1) osgEphemeris, by Don Burns
(http://andesengineering.com/Projects/OsgEphemeris) - uses OSG (and
osgProducer) to create virtual environments for sky, moon, planets, and
stars.

 

(2) Delta3D (http://www.delta3d.org <http://www.delta3d.org/> ) - uses
OSG in developing a gaming and simulation engine.

 

(3) FlightGear (http://www.flightgear.org <http://www.flightgear.org/> )
- SVN project uses OSG, but prior releases use straight OpenGL for
environment rendering (I believe this part is handled using SimGear,
www.simgear.org <http://www.simgear.org/> ).

 

All references are open-source, so they should provide some good
examples how environment rendering is handled both with OSG and OpenGL.

Hi Jim, 

do you have a example or demo of the sky-dome implemenation with the
clouds ?

OSG can be used to render a sky dome/box and clouds
(I've done it).

For cumulus clouds, used libnoise to 
procedurally-generate textures and
and a custom sprite node that rendered
a set of viewplane-aligned blended quads
(OSG::Billboard has/had problems staying rotated to
viewplane).
