|
|
|
|
The *Flip Faces Node* reverses the order of the vertices and edges of each selected face.
|
|
The most common use of this node is to flip the normals of a face.
|
|
Any :ref:`face corner domain <attribute-domains>` attributes of selected faces are also reversed.
|
|
|
|
Though this node is usually used to affect normals, it is not called "Flip Normals" for an important reason.
|
|
The node does not actually interact with normals directly. Normals are defined by the
|
|
`right hande rule <https://en.wikipedia.org/wiki/Right-hand_rule#Curve_orientation_and_normal_vectors>`__,
|
|
so if a face's vertex list is reversed, then its normal will point in the opposite direction.

======
|
|
|
|
Mesh
|
|
Standard geometry input.
|
|
|
|
Selection
|
|
Whether to flip the direction of each face.
|
|
True values mean the face will be flipped, false means the face will be unaffected.
