|1= an "architecture astronaut" might end up wondering what would be required to support arbitrary [http://www.orbiterwiki.org/wiki/Category:Celestial_bodies celestial bodies] (think Moon, Mars) by exposing those using a property-configurable texture and corresponding parameters for an osg::Shape based array of LOD-enabled spheres :D ) | |||
For instance, imagine a custom PropertyList-XML dialect for instantiating celestial bodies by specifying a position, sie, and 3D models/texture sheets for different LODs. | |||
And yes, I would be willing to help work out the SGSubsystem/C++ and OSG magic/patches to make that happen in a generic fashion. | |||
We already have support for adding models procedurally via /models, we can dynamically load/create/modify textures using Canvas, and we do support effects & shaders - so it would mainly seem like a matter of reviewing those features to come up with an interface so that arbitrary celestial bodies can be supported using these existing features. | |||
(note that this seems to be how celestial bodies in Orbiter are structured: [http://www.orbiterwiki.org/wiki/Category:Add-ons http://www.orbiterwiki.org/wiki/Category:Add-ons] ) | |||
