Constructor & Destructor Documentation

◆ GlPointCloud()

GlPointCloud	(	PointCloud *	pointCloud,
		bool	showIn2D = false )

explicit

Constructor with a point cloud (that is not owned), and option to enable 2D view visibility.

The rendering in 2D views is disabled by default, since it might yield wrong results based on whether the image matrices are set to be used or not. Therefore it has to be explicitly set, typically when a rendering of a 2D point set on an image is intended.
