◆ 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

◆ getFieldName()

template<typename PointT >
virtual std::string pcl::visualization::PointCloudColorHandlerRGBAField< PointT >::getFieldName ( ) const
inlinevirtual

Get the name of the field used.

◆ getName()

template<typename PointT >
virtual std::string pcl::visualization::PointCloudColorHandlerRGBAField< PointT >::getName ( ) const

◆ setInputCloud()

template<typename PointT >
void pcl::visualization::PointCloudColorHandlerRGBAField< PointT >::setInputCloud ( const PointCloudConstPtr cloud)
virtual

Set the input cloud to be used.

Parameters
[in]cloudthe input cloud to be used by the handler
