I've seen a number of examples converting Latitude and Longitude into an OpenGL coordinate system. For example, this
one is particularly useful. However, I haven't found relevant examples that include elevation/altitude. I was hoping someone might provide me with an example.
The original lat, long, and altitude will be in the WGS 84 ellipsoid, and OpenGL will be using the right-hand Y-Up coordinate system. Basically, I'm looking at using OpenGL to render models from Google's 3D warehouse that are associated with Google Earth. These come as collada files with a Z-Up orientation.
Thanks for any help.
