Description

Defined by computing sunlight, penumbra and umbra intervals as seen at specified location using specified selection of eclipsing bodies.

Object Model

Public Properties

EclipsingBodies	A custom list of eclipsing bodies. This list is used if UseObjectEclipsingBodies is set to false.
Location	The location point to compute sunlight, penumbra and umbra.
UseObjectEclipsingBodies	When true, configure eclipsing bodies list based on that of parent STK Object.

Example

Create and configure lighting event interval collection.
