Detailed Description

Generic field handler class for colors.

Uses an user given field to extract 1D data and display the color at each point using a min-max lookup table.

◆ getColor()

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

overridevirtual

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

Deriving handlers should override this method. The default implementation is provided only for backwards compatibility with handlers that were written before PCL 1.10.0 and will be removed in future.

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< pcl::PCLPointCloud2 >.
