The Qgis class provides global constants for use throughout the application.
Definition: qgis.h:72
AltitudeClamping
Altitude clamping.
Definition: qgis.h:2190
@ Relative
Elevation is relative to terrain height (final elevation = terrain elevation + feature elevation)
AltitudeBinding
Altitude binding.
Definition: qgis.h:2203
@ Centroid
Clamp just centroid of feature.
Entity that handles the exporting of 3D scene.
CullingMode
Triangle culling mode.
Definition: qgs3dtypes.h:36
@ NoCulling
Will render both front and back faces of triangles.
Definition: qgs3dtypes.h:37
virtual bool exportGeometries(Qgs3DSceneExporter *exporter, Qt3DCore::QEntity *entity, const QString &objectNamePrefix) const

The class is used as a container of context for various read/write operations on other objects.
Represents a vector layer which manages a vector based data sets.
Handles storage of information regarding WKB types and their properties.
