I think none of the lights are ever processed by any shader code, so they would all get some default non-shader fogging and never fog correctly. It might be as trivial as just running them through model-default.eff, but I can also write a dedicated shader for lights as they won't need any ambient of diffuse light computations. It might also be much cheaper to simply fade them to transparent and use the fog color from whatever is behind rather than to comnpute the actual fog color (which is moderately expensive). This strategy seems to be working well for heavily fogged clouds. Certainly all the runway lighting sticks out worst, because it make the runway outline visible through very dense fogging, which sort of defeats the point of dense fog obscuring the runway. I could probably live with VASI being seen from a larger distance, I guess they're pretty powerful lights, and fog fading of a light source must be a function of the light intensity (and direction - and aerosol size... and...) in reality. > I don't think it's a major hold-up, but it would be nice to get it > resolved. I'll be travelling next week - hotel rooms have often been the location for major code development, so I'll try to get the wake shader done then. If we agree that this doesn't constitute a novel feature and can be added despite the feature freeze. * Thorsten ------------------------------------------------------------------------------ This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev _______________________________________________ Flightgear-devel mailing list Flightgear-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/flightgear-devel
