I understand the discrepancy. The real question is why the originator of the thread was using a sphere in the first place and not the ellipsoid to place the models...

Hi Shayne and Akilan, I suspect your problem has something to do with your shape drawable where you're using a sphere in your code. That is what I was trying to say, If you do your calculations with an ellipsoid model, but then you try to draw these positions in a ShapeDrawable::Sphere you'll never see the models in their right place. You have to draw on an Ellipsoid, not a Sphere. Depending on where you are putting our model (near the equator or near the poles) the difference could be very large.
