In this demo you can explore the stereographic projection of the sphere onto the plane.
Stereographic Projection is a very lightweight but useful application that was designed in order to provide you with a simple means of visualizing a projection of a sphere (the Earth) onto a plane.<br /><br />The unit sphere is projected from the North Pole onto the plane z=-1. z=-1 is used instead of the z=0 plane so the sphere remains completely visible.<br /><br />When the mouse is over the sphere, dragging rotates the sphere.<br /><br />Note that while the sphere is rotating there is a slight error in the texturing, going between the images of the two poles. When the sphere stops, this error is corrected.<br /><br />Otherwise, dragging the mouse invokes the current tool on the world. Default tool is rotate tool (Tools are selectable from the tool bar.)
