Detailed Description

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

Member Function Documentation

◆ getColor()

template<typename PointT >

vtkSmartPointer< vtkDataArray > pcl::visualization::PointCloudColorHandlerRGBAField< 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 >.
