This is used to transform (render) QgsGeometry to node for QtQuick scene graph.
A geometry is the spatial representation of a feature.
Definition: qgsgeometry.h:111
Abstract base class for all geometries.
Point geometry type, with support for z-dimension and m-values.
Definition: qgspoint.h:37
GeometryType
The geometry types are used to group QgsWkbTypes::Type in a coarse way.
Definition: qgswkbtypes.h:139
Line string geometry type, with support for z-dimension and m-values.
Definition: qgslinestring.h:43
Polygon geometry type.
