Normals
Filter > Normals panel contains filters operating on point normals.
Filters are directly applied on loaded points, Blender undo system does not work. To have single history state to return to, see Store/Restore state operators
Estimate Normals
Compute normals of point cloud. Normals are oriented with respect to the existing point cloud normals if exists and provided. If not, there are several methods to determine orientation: Direction, Camera Location and Tangent Planes.
Add Normals
Add normals from three scalar fields.
Some file formats does not store normals, but allows adding of custom scalar fields. Normals x, y, z values are added, but there is no standard for field names. Most common are NormalX, nx, normal_x, normalx or normal x.
