I'd like to ask if there are three different types how to triangulate ellipsoid (which are different). The requirement is that every point of triangle should lie on the ellipsoid.

Thank you, Adam

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question.If this question can be reworded to fit the rules in the help center, please edit the question.

Could you explain in some more detail what you're trying to do? Maybe add some examples/pictures. As it is stated now, I don't have a clue of what the question is (although that may be my lack of knowledge) – Ragnar Mar 8 '14 at 21:52
As with most spaces, there are infinitely many triangulation a for the sphere: Find one and then subdivide. – studiosus Mar 8 '14 at 21:56
What exactly is a “type” of triangulation in your definition? Right now I cannot think of a way to classify all triangulations of the ellipsoid into one of three classes, but that doesn't mean that there are no such classes. – MvG Mar 8 '14 at 22:02
This is something that I don't understand as well... I'm supposed to find three different types of ellipsoid triangulation. All three should be different -- meaning that I can't go from one to other just by adjusting some parameter (e.g. number of latitutes and meridians). All points used should lie on the ellipsoid and for all three there should be a way how to approximate the ellipsoid to whatever error. This is what my assignment says... – Adam Mar 8 '14 at 22:16
