You could use a sphere and difference/intersection.
The mesh approach would likely involve using one of the many methods of starting
with a platonic solid and subdividing each face into more triangles and
normalizing the distance of the new vertices so that the triangles progressively
approximate the surface of the spherical triangle.
Heck, you could probably also use lathe and SOR.
Facetted_sphere or Ring_Sphere macros in shapes3.inc
