Polygon line modifier plug-ins

Polyline modifier plug-ins act on the same principle as mesh modifiers, except that they alter polygon lines instead of polygon meshes.

Specifying polygon line modifier plug-ins

Polyline plug-ins are distinguished by the fact that they accept PolylineMesh3 as their first parameter and return PolylineMesh3 as their result and that both of these input and output belong to the same port group.

[OutputPort( Group = "primary" )]
public static PolylineMesh3 MyPolylineModifier( [InputPort( Group = "primary" )] PolylineMesh3 polylineInput )
	// Take polylineInput, alter it, and return as result...
