Your shape is probably not possible to divide with equal triangles (without the edge shape changing to at least some amount, or the curvature). WebThe Basics of Spherical Geometry. A sphere is defined as a closed surface in 3D formed by a set of points an equal distance R from the centre of the sphere, O. The sphere's radius is the distance from the centre of the sphere to the sphere's surface, so based on the definition given above, the radius of the sphere = R.

Geodesic polyhedra are constructed by subdividing faces of simpler polyhedra, and then projecting the new vertices onto the surface of a sphere.
