Extrude Separate Faces¶

Functionality¶

This node applies Extrude operator to each of input faces separately. After that, resulting faces can be scaled up or down by specified factor. It is possible to provide specific extrude and scaling factors for each face. As an option, transformation matrix may be provided for each face.

Inputs¶

This node has the following inputs:

Vertices
Edges
Polygons
Mask. List of boolean or integer flags. Zero means do not process face with corresponding index. If this input is not connected, then by default all faces will be processed.
Height. Extrude factor.
Scale. Scaling factor.
Matrix. Transformation matrix. Default value is the identity matrix.
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.

Parameters¶

This node has the following parameters:

Parameter	Type	Default	Description
Mode	Enumeration	Normal	This defines how the transformation of faces being extruded is specified. There are the following modes available: Normal: the transformation is defined by Height and Scale inputs (see below). Matrix: the transformation is defined by the Matrix input.
Mask mode	Enumeration	Do not extrude	This defines what exactly to do with faces that are masked out. The available modes are: Do not extrude. Do not perform extrusion operation on such faces. Do not transform. Such faces will be extruded, but will not be transformed (moved or scaled away from positions of original vertices); so the new vertices will be at the same positions as original ones. You may want to remove them with Remove Doubles node, or move them with another node. This parameter is available in the N panel only.
Height	Float	0.0	Extrude factor as a portion of face normal length. Default value of zero means do not extrude. Negative value means extrude to the opposite direction. This parameter can be also provided via corresponding input. The input and parameter are available only if Mode is set to Normal.
Scale	Float	1.0	Scale factor. Default value of 1 means do not scale. The input and parameter are available only if Mode is set to Normal.
Mask Output	Enumeration	Out	This defines which faces will be marked with 1 in the Mask output. Several modes may be selected together. The available modes are: Mask. The faces which were masked out by the Mask input. In. Inner faces of the extrusion, i.e. the same faces that are in the ExtrudedPolys output. Out. Outer faces of the extrusion; these are the same as in OtherPolys output, excluding faces that were masked out by Mask input.

Outputs¶

This node has the following outputs:

Vertices
Edges
Polygons. All faces of resulting mesh.
ExtrudedPolys. Only extruded faces of resulting mesh.
OtherPolys. All other faces of resulting mesh.
Mask. Mask for faces of the resulting mesh; which faces are selected depends on the Mask Output parameter.
FaceData. List containing data items from the FaceData input, which contains one item for each output mesh face.
