Split Faces¶

Functionality¶

This node splits NGon faces of the input mesh into smaller faces by one of two available rules:

Split non-planar faces. In this mode, it will split NGon faces, that are not planar (flat), into smaller planar (flat) faces. There is adjustable limit of what exactly faces should be considered non-planar. For example, if the angle between two parts of the face is less than 1 degree, we can consider it planar.
Split concave faces. This will split faces that are not convex polygons. Please note that this does not mean that it will split faces so that the resulting mesh will make convex volume - it only checks for convex polygons.

This node has the following inputs:

Vertices. This input is mandatory.
Edges.
Faces. This input is mandatory.
FaceMask. The mask for faces which should be considered. By default, all faces are considered.
MaxAngle. Maximum angle (in degrees) between parts of the face for it to be considered planar. The default value is 5 degrees. This input can also be specified as parameter. This input is only visible when Mode parameter is set to Non-planar.
FaceData. List containing an arbitrary data item for each face of input mesh. For example, this may be used to provide material indexes of input mesh faces. Optional input.

This node has the following parameters:

Mode. This defines which faces should be split. Available values are Non-planar and Concave. The default value is Non-planar.

This node has the following outputs:

Vertices. Output mesh vertices.
Edges. Output mesh edges.
Faces. Output mesh faces.
FaceData. List containing data items from the FaceData input, which contains one item for each output mesh face.
