Prepared data container for QgsPointCloudClassifiedRenderer.
Renders point clouds by a classification attribute.
Encapsulates the render context for a 2D point cloud rendering operation.
Abstract base class for 2d point cloud renderers.
Base class for 2d point cloud renderer prepared data containers.
The class is used as a container of context for various read/write operations on other objects.
