Glens simulates a gravitational lens composed of any number of punctual
|
|
deflectors. Light comes from a punctual light source at an infinite distance,
|
|
the direction of which can be specified. It is then deflected by a
|
|
distribution of punctual deflectors (such as a black hole) into a small
|
|
region of space. The rays can be seen, and directions and parameters
|
|
specified to see multiple images, or the famous "Einstein ring".
