This Demonstration highlights the properties of stereographic projection. This is achieved by mapping simple geometric shapes from the or
plane onto the unit sphere using inverse stereographic projection. The inverse stereographic projection of the point
to the unit-sphere is the point

Snapshots
Details
These snapshots illustrate some properties of stereographic projection:
Snapshot 1: preservation of angles (conformality)
Snapshot 2: circles in the plane are mapped to circles on the sphere
Snapshot 3: lines in the plane are mapped to great circles on the sphere
