Calculate Normals


This node calculates normals for faces and edges of given mesh. Normals can be calculated even for meshes without faces, i.e. curves.


This node has the following inputs:

  • Vertices
  • Edges
  • Polygons


This node has the following outputs:

  • FaceNormals. Normals of faces. This output will be empty if Polygons input is empty.
  • VertexNormals. Normals of vertices.

Examples of usage

Move each face of cube along its normal:

Normals can be also calculated for closed curves:
