QgsAbstract3DRenderer class

Base class for all renderers that may to participate in 3D view.

3D renderers implement the method createEntity() that returns a new 3D entity - that entity will be added to the 3D scene to represent data in renderer's display style.

Renderers may store some custom properties (e.g. materials, sizes) that are written to and read from XML. It is therefore not recommended to store large amount of data within a renderer (e.g. arrays of vertices).

Derived classes

class QgsVectorLayer3DRenderer

3D renderer that renders all features of a vector layer with the same 3D symbol.

Constructors, destructors, conversion operators

QgsAbstract3DRenderer() protected defaulted

Default constructor.

Public functions

auto clone() const -> QgsAbstract3DRenderer* pure virtual

Returns a cloned instance.

auto createEntity(const Qgs3DMapSettings& map) const -> Qt3DCore::QEntity* pure virtual

Returns a 3D entity that will be used to show renderer's data in 3D scene.

void readXml(const QDomElement& elem, const QgsReadWriteContext& context) pure virtual

Reads renderer's properties from given XML element.

void resolveReferences(const QgsProject& project) virtual

Resolves references to other objects - second phase of loading - after readXml()

auto type() const -> QString pure virtual

Returns unique identifier of the renderer class (used to identify subclass)

void writeXml(QDomElement& elem, const QgsReadWriteContext& context) const pure virtual

Writes renderer's properties to given XML element.
