I've successfully initialized Vostok at 1.000.000 ft after using this patch and sunsequently injected it into a stable orbit - basic orbital flight dynamics seems to be checking out well. I haven't tried flying it up yet (need to go through the red zone where rendering looks really ugly...). But thanks for the patch! > I was wondering, instead of using the Blue Marble texture it might be a > good idea to render our own texture using the global scenery.

The charm of a really dumb approach is that it's really just a textured sphere, i.e. texturing it a different way is really easy and should even work at runtime like we change aircraft liveries. Personally I prefer Blue Marble, but I see the sense in what you're saying. * Thorsten ------------------------------------------------------------------------------ This SF email is sponsosred by: Try Windows Azure free for 90 days Click Here http://p.sf.net/sfu/sfd2d-msazure _______________________________________________ Flightgear-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/flightgear-devel
