Represents an individual category (class) from a QgsPointCloudClassifiedRenderer.
Renders point clouds by a classification attribute.
Represents a map layer supporting display of point clouds.
Base class for point cloud 2D renderer settings widgets.
Abstract base class for 2d point cloud renderers.
A QProxyStyle subclass which correctly sets the base style to match the QGIS application style,...
