Constructor & Destructor Documentation

◆ Qgs3DExportObject()

Qgs3DExportObject::Qgs3DExportObject ( const QString & name )

inline

Qgs3DExportObject Constructs an export object that will be filled with coordinates later.

Parameters

parentName	The name of the parent (Will be useful to define scene hierarchy)
parent	The parent QObject (we use this to delete the Qgs3DExportObject instance once the exporter instance is deallocated)
