Sphere

In order to build spheres, introduce the Center Point of the initial sphere. For the radius controls, the user can set the radius for the initial sphere using Initial radius. It is possible to create more than one sphere using the Radius samples. In that case, the radius increment between two consecutive spheres is controlled via Increment radius. Theta coordinates and phi coordinates let the user specify how many points to create from the sphere and whether to use the entire sphere curvature or just a slice of the sphere.
