Detailed Description

template<typename PointT>
class pcl::visualization::PointCloudColorHandlerGenericField< PointT >

◆ getColor()

template<typename PointT>
vtkSmartPointer< vtkDataArray > pcl::visualization::PointCloudColorHandlerGenericField< 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
