Base metadata class for 3D renderers.
QString mType
Type used within QGIS for identification (the same what renderer's type() returns)
virtual ~Qgs3DRendererAbstractMetadata()=default
virtual QgsAbstract3DRenderer * createRenderer(QDomElement &elem, const QgsReadWriteContext &context)=0
Returns new instance of the renderer given the DOM element.
Keeps track of available 3D renderers.
Qgs3DRendererRegistry()=default
Creates registry of 3D renderers.
Base class for all renderers that may to participate in 3D view.
The class is used as a container of context for various read/write operations on other objects.
