OpenGL - Convert Latitude Longitude and Altitude to x,y,z

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.

Regards,
David
