My goal is to render airplane trajectory (which is just a vector of wgs-84 points: lat, lon, alt).
I did it with C++ using Feature and Feature node. Looks OK, but following question arises: is it correct way to solve such a problem? Is it optimal?
Second thing: i would like to set vertices colors depending on parameters of points, for example speed or altitude. Is it possible? The only way I found is to kinda invent ColorSymbol and deal with it inside BuildGeometryFilter or modify LineSymbol. But this approach is pretty complicated for me. Is there any way to do it simplier?
Third question is: is osgEarth a good choice to render realtime trajectory data?
