Detailed Description

3

Abstract base class for 3D symbols that are used by VectorLayer3DRenderer objects.

3D symbol objects define appearance of GIS data.

Warning
This is not considered stable API, and may change in future QGIS releases. It is exposed to the Python bindings as a tech preview only.
Note
Prior to QGIS 3.16 this was available through the QGIS 3D library.
Since
QGIS 3.0

Member Function Documentation

◆ clone()

virtual QgsAbstract3DSymbol* QgsAbstract3DSymbol::clone ( ) const
pure virtual

Returns a new instance of the symbol with the same settings.

Implemented in QgsMesh3DSymbol.

◆ compatibleGeometryTypes()

QList< QgsWkbTypes::GeometryType > QgsAbstract3DSymbol::compatibleGeometryTypes ( ) const
virtual

Returns the list of the vector layer geometry types which are compatible with this symbol.

Since
QGIS 3.16

Definition at line 22 of file qgsabstract3dsymbol.cpp.

◆ copyBaseSettings()

void QgsAbstract3DSymbol::copyBaseSettings ( QgsAbstract3DSymbol destination) const
protected

Copies base class settings from this object to a destination object.

Definition at line 33 of file qgsabstract3dsymbol.cpp.

◆ dataDefinedProperties() [1/2]

QgsPropertyCollection& QgsAbstract3DSymbol::dataDefinedProperties ( )
inline

Returns a reference to the symbol layer's property collection, used for data defined overrides.

Definition at line 78 of file qgsabstract3dsymbol.h.

◆ dataDefinedProperties() [2/2]

const QgsPropertyCollection& QgsAbstract3DSymbol::dataDefinedProperties ( ) const
inline

Returns a reference to the symbol layer's property collection, used for data defined overrides.

Definition at line 81 of file qgsabstract3dsymbol.h.

◆ exportGeometries()

bool QgsAbstract3DSymbol::exportGeometries ( Qgs3DSceneExporter exporter,
Qt3DCore::QEntity *  entity,
const QString &  objectNamePrefix 
) const
virtual

Exports the geometries contained within the hierarchy of entity.

Returns whether any objects were exported If this function is not overloaded we don't try to export anything

Definition at line 53 of file qgsabstract3dsymbol.cpp.

◆ propertyDefinitions()

const QgsPropertiesDefinition & QgsAbstract3DSymbol::propertyDefinitions ( )
static

Returns the symbol layer property definitions.

Definition at line 27 of file qgsabstract3dsymbol.cpp.

◆ readXml()

virtual void QgsAbstract3DSymbol::readXml ( const QDomElement &  elem,
const QgsReadWriteContext context 
)
pure virtual

Reads symbol configuration from the given DOM element.

Implemented in QgsMesh3DSymbol.

◆ setDataDefinedProperties()

void QgsAbstract3DSymbol::setDataDefinedProperties ( const QgsPropertyCollection collection)
inline

Sets the symbol layer's property collection, used for data defined overrides.

Definition at line 84 of file qgsabstract3dsymbol.h.

◆ type()

virtual QString QgsAbstract3DSymbol::type ( ) const
pure virtual

Returns identifier of symbol type. Each 3D symbol implementation should return a different type.

Implemented in QgsMesh3DSymbol.

◆ writeXml()

virtual void QgsAbstract3DSymbol::writeXml ( QDomElement &  elem,
const QgsReadWriteContext context 
) const
pure virtual

Writes symbol configuration to the given DOM element.
