What are we doing differently?
I think that the newer OpenGL cards can handle *many* more polygons in the scenery then we are currently throwing at them as long as we present them clumped according to 'OpenGL state' which shoud be the case with the basic scenery. Note the recent improvements due to the sorting of the 'buildings' models by state at load time. > BTW you didn't get around to explaining how we 'modulate the alpha channel' > in .xml in our discussion re lighting 3d instruments. (I might be forced to > re-tell the 2 men in a balloon story ... :-)) Oh please do keep telling that story as it points out the absurdity of thinking in lat lon with it's requirement for transcendentals so well, which by the way, are not necessary when using a sphere of one Earth Radius :-) It is kind of like using US vs Metric measurements, it is all about what you are use to, and, it is time for the ECEF coordinate system to be adopted !!
