- Returns
- true if component is to be drawn on the map.
Reimplemented from SkyComponent.
Definition at line 43 of file horizoncomponent.cpp.
◆ update()
|
overridevirtual |
Update the sky position(s) of this component.
This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of its member object(s). However, the precession and nutation must also be recomputed periodically. num
Pointer to the KSNumbers object
