Detailed Description

Label field handler class for colors.

Paints the points according to their labels, assigning a unique color from a predefined color lookup table to each label.

Member Typedef Documentation

pcl::visualization::PointCloudColorHandlerLabelField< pcl::PCLPointCloud2 >::PointCloudColorHandlerLabelField	(	const PointCloudConstPtr &	cloud,
		const bool	static_mapping = true )

Constructor.

Parameters

[in] static_mapping Use a static colormapping from label_id to color (default true)

vtkSmartPointer< vtkDataArray > pcl::visualization::PointCloudColorHandlerLabelField< pcl::PCLPointCloud2 >::getColor ( ) const

overridevirtual

Obtain the actual color for the input dataset as a VTK data array.

Deriving handlers should override this method.

Returns: smart pointer to VTK array if the operation was successful (the handler is capable and the input cloud was given), a null pointer otherwise
