Hi everybody,(adsbygoogle = window.adsbygoogle || []).push({});

I am working on a 3D Sphere rotation algorithm.

I have a point X lying on a unit sphere in the spherical coordinate system. I have divided the sphere in regions or areas delimited by 3 (polar areas) and 4 points which are also on the unit sphere. The regions have different labels.

I need to find out on which spherical surface (region 1,2,...) lies point X. Then, when I randomly rotate the sphere but kept fixed point X, which will be the new region? I need something general to handle any rotation of the sphere.

Can any one tell me how to do this?

Thanks a lot in advance.

Esteban
