Up: The Poincaré Disk

The Poincaré Disk Java Applet

What is happening here . . .

The model below contains two pairs of points -- a blue pair in the interior, and a red pair on the boundary. Each pair of points determines a unique line. Using the mouse you can move the blue points about the interior of the disk and the red points about the boundary to observe the behavior of lines in the disk.
