◆ setInputNormals()

template<typename PointInT , typename PointNT , typename PointOutT >

void pcl::FeatureFromNormals< PointInT, PointNT, PointOutT >::setInputNormals ( const PointCloudNConstPtr & normals )

inline

Provide a pointer to the input dataset that contains the point normals of the XYZ dataset.

In case of search surface is set to be different from the input cloud, normals should correspond to the search surface, not the input cloud!

Parameters

[in] normals the const boost shared pointer to a PointCloud of normals. By convention, L2 norm of each normal should be 1.
