Detailed Description

Main class for Stellarium core processing.

This class provides services like management of sky projections, tone conversion, or reference frame conversion. It is used by the various StelModules to update and display themself. There is currently only one StelCore instance in Stellarium, but in the future they may be more, allowing for example to display several independent views of the sky at the same time.
