Constructor & Destructor Documentation

◆ PointCloudColorHandlerLabelField() [1/2]

template<typename PointT >

pcl::visualization::PointCloudColorHandlerLabelField< PointT >::PointCloudColorHandlerLabelField ( const bool static_mapping = true )

inline

Constructor.

Parameters

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

Definition at line 473 of file point_cloud_color_handlers.h.

References pcl::visualization::PointCloudColorHandler< PointT >::capable_.

◆ PointCloudColorHandlerLabelField() [2/2]

template<typename PointT >

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

inline

Constructor.

Parameters

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

Member Function Documentation

◆ getColor()

template<typename PointT >

vtkSmartPointer< vtkDataArray > pcl::visualization::PointCloudColorHandlerLabelField< PointT >::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

Implements pcl::visualization::PointCloudColorHandler< PointT >.
