QPointF toScreen(const SkyPoint *o, bool oRefract=true, bool *onVisibleHemisphere=nullptr) const
This is exactly the same as toScreenVec but it returns a QPointF.
Definition projector.cpp:93
bool onScreen(const QPointF &p) const
Check whether the projected point is on-screen.
Definition projector.cpp:98
bool checkVisibility(const SkyPoint *p) const
Determine if the skypoint p is likely to be visible in the display window.
virtual void show()
shows all child nodes (sets opacity of m_opacity to 1)
Definition skynode.cpp:27
virtual void hide()
hides all child nodes (sets opacity of m_opacity to 0)
