A class to represent a 2D point.
Definition: qgspointxy.h:43
3 3D symbol that draws polygon geometries as planar polygons, optionally extruded (with added walls)...
3 Definition of the world
3 Class derived from Qt3DRender::QGeometry that represents polygons tessellated into 3D geometry...
This class wraps a request for features to a vector layer (or directly its vector data provider)...
Represents a vector layer which manages a vector based data sets.
