Is Face Planar Node
For example, a non-planar face can be created by moving a single vertex in a face but not the others. Triangles will always be planar.
The distance a point can be from the surface before the face is no longer considered planar.
This node has no properties.
Whether each mesh face is planar.
Combined with the Set material, this node is used to visualize all non-planar faces in a mesh.
