Detailed Description

Provides virtual functions for update of coordinates and nodes hiding.

A QSGTransformNode derived class that has to be subclassed by node containers like PlanetNode and PointSourceNode. SkyObject * that is passed as parameter to constructor is used in subclasses to calculate new coordinates in update(). Subclasses have to implement hide() so that each of their child nodes can be hidden.

visible()

bool SkyNode::visible

(

)

Returns

true if object is visible (m_opacity->opacity() != 0) else returns false
