Member Function Documentation

◆ getColor()

template<typename PointT >

virtual vtkSmartPointer<vtkDataArray> pcl::visualization::PointCloudColorHandler< PointT >::getColor ( ) const

pure virtual

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

Implemented in pcl::visualization::PointCloudColorHandlerLabelField< PointT >, pcl::visualization::PointCloudColorHandlerRGBAField< PointT >, pcl::visualization::PointCloudColorHandlerGenericField< PointT >, pcl::visualization::PointCloudColorHandlerHSVField< PointT >, pcl::visualization::PointCloudColorHandlerRGBField< PointT >, pcl::visualization::PointCloudColorHandlerCustom< PointT >, pcl::visualization::PointCloudColorHandlerRandom< PointT >, and pcl::visualization::PointCloudColorHandlerRGBHack< PointT >.
