-====== Spline Deformation (Node) ======
+====== Spline Deformation (Node + Modifier) ======
 The Spline Deformation allows you to deform an mesh along an axis, using a spline as the target shape.

+There a node to be used in the Nodal Displacement editor located in the Primitive/Geometry tab of a mesh.
+db&w Spline Displacement is also available as a modifier for the object/displacement tab.

+===== Controls =====
+==== Spline ====
+This pop-up allows you to select the spline that's used to deform the geometry.
+==== Deformation Axis ====
+This defines the axis that's used for the deformation.
+Basically, the distance of every vertex to the mesh origin is computed along this axis.
+That distance is in turn used to find a transformation on the spline. The vertex is then moved accordingly.
+==== Fit to Spline ====
+If enabled, the mesh will be squashed/stretch to fit the spline. The Offset will be disabled.
+==== Offset Distance / Percentage ====
+This offsets the distance along the spline used to compute the deformation. Essentially, the deformed mesh slides across the spline.
+Depending on the Mode, this is either an absolute distance or a percentage of the spline length.
+==== Mode ====
+This changes how the deformation offset on the spline is computed:
+=== Absolute ===
+The Offset is an absolute distance on the spline.
+=== Relative ===
+The Offset is a percentage of the spline length.
+==== Pre-Behaviour / Post-Behaviour ====
+{{ :tools:s-tk:pasted:20200124-145415.png}}
+These controls define what happens if a vertex would be evaluated beyond the start or the end of the spline.
+These will ((currently)) be ignored if the spline is a closed spline. In that case, the deformation will loop.
+=== Hold ===
+This will limit the deformation to the spline.
+=== Extend ===
+Vertices beyond the spline will be positioned on a line extending from the spline, using the direction as defined by the first/last knot.
+=== Loop ===
+Vertices beyond the spline will loop the spline deformation.
+=== Mirror ===
+Vertices beyond the spline will mirror the spline deformation.
+=== Axis Mirror ===
+Vertices beyond the spline will mirror the spline deformation, but also mirror the direction of the displacement across the defined axis.
+==== Reference Item  ====
+Allows for picking an item that acts like a pivot for the deformation on the mesh.
+==== World Coordinates ====
+Evaluates the spline in world as opposed to local coordinates.
