Atlas currently contains a copy of the SimGear render-to-texture code (to avoid depending on SimGear CVS) - you could possibly get this working in Atlas if FG won't start for you - and then it should also work in SimGear/FlightGear. Question, though : what is FG using render-to-texture *for*? Atlas is using render-to-texture to avoid image corruption due to overlaid windows, and to allow the creation of images larger than the screen resolution (on some hardware). I don't know what Erik has in mind, but I think that render-to-texture would be useful in FG for procedurally drawing complex 2D images into a texture in real-time (eg. gps unit / glass cockpit display), and then using that to texture a 3D instrument face. I have an inkling in the back of my mind that it might also possibly be useful for drawing impostors for the 3D cloud rendering, but that's just a wild guess.

Re: [Flightgear-devel] Mac os x simgear build break with RenderTexture.cpp
Quoting David Luff : I have an inkling in the back of my mind that it might also possibly be useful for drawing impostors for the 3D cloud rendering, but that's just a wild guess. Mark Harris, who wrote both RenderTexture and 3d clouds, used the framebuffer to do the latter's impostors. But the resulting image has to be copied to the texture memory and this could be avoided by the use of pbuffer. Note that if we are careful to render to texture *before* the initial glClear, we could use this path ( drawing to frame back buffer and then copy image to texture memory ) for systems that will not support pbuffer. -Fred ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel 2f585eeea02e2c79d7b1d8c4963bae2d
