Visibility Check page

This page allows you to specify one or more Eye or Viewing locations together with one or more Obstruction points. At least one eye and one obstruction point must be given.

Points can be turned on or off, which allows you to investigate different scenarios without having to delete points.

Clicking the Calculate button will cause the obscured length for the current set up, to be displayed, which can then be compared with the ship's length. The obscured length is the greatest length that will be in shadow by all active pairs of eye and obstruction points.
