Stereographic Projection Field

A projection chamber for observing how points on a sphere stretch onto a plane, and how the north pole moves toward infinity.

projection Prototype

First observation Use PROJECT to reveal mapping rays. Use INFINITY to watch northern points stretch far across the plane.

OPERATION PANEL

CHAMBER STATUS

Use PROJECT / INFINITY / ROTATE to observe projection rays from the sphere to the plane.
Switch SPHERE / GRID / CIRCLES to compare different traces of the same projection.
Track how points near the north pole stretch outward toward infinity.

TRACE MODE

LENS

BANDS 8 SCALE 1.00 NORTH BIAS 0.42

SYSTEM NOTE

For a sphere point P = (X, Y, Z), x = X / (1 - Z), y = Y / (1 - Z). As Z approaches 1, the projected point stretches outward toward infinity.
