 Command line: PC_RECALC_NORMALS

Cloud points have such parameter as normal. Point normals are used for cloud vectorization (triangulation, recognition of vector primitives). For better recognition, points of one cloud surface should have collinear normals.

Sometimes it may be necessary to adjust (recalculate) point normals before triangulation. Normals are corrected by the Re-calculation of Normals command.

The direction of normals is checked visually. To do this, it is necessary to recolor the cloud in accordance with normals direction. In the View Mode command’s dialog box, select a new Normal coloring type.

Cloud points will be colored depending on the direction of their normals. At that, points with normals collinear with a certain coordinate axis will have the color of this axis.

That’s approximately how building points should look for good triangulation – normal of points of each plane are oriented to own direction

The command options are set on the Properties bar.
