Member Function Documentation

◆ update()

void PointListComponent::update ( KSNumbers num = nullptr)

Update the sky positions of this component.

This function usually just updates the Horizontal (Azimuth/Altitude) coordinates of the objects in this component. However, the precession and nutation must also be recomputed periodically. Requests to do so are sent through the doPrecess parameter. num Pointer to the KSNumbers object

By default, the num parameter is nullptr, indicating that Precession/Nutation computation should be skipped; this computation is only occasionally required.

Reimplemented from SkyComponent.
