SpletWe use PCL’s :pcl:`NormalEstimation ` class to compute the surface normals. To do so, we must specify the input point cloud, the KdTree to use when searching for neighboring points, and the radius that defines each point’s neighborhood. We then compute the surface normals and store them in a member variable for later use.
