-====== Spline Proximity (in Progress, node) ======
+{{ :tools:s-tk:pasted:20190819-155100.png}}
+====== Spline Proximity (node) ======
 This node computes the distance of the current point/shading spot to the closest point on the selected spline.
-{{:tools:s-tk:pasted:20190819-155100.png}}
+The accuracy of this node relies on the number of Evaluation Steps defined in the [[tools:s-tk:primitive|]] or the [[tools:s-tk:prefs|]].
 ===== Controls =====
 ==== Spline ====
+Selects the spline used by this node.
 ==== World Coordinates ====
+Switches all evaluation to world coordinates.
 ==== Minimum Distance ====
 ==== Maximum Distance ====
+These two define the minimum and maximum range for the normalised outputs. The output will ne 0 at the minimum range and 1.0 at the maximum range.
 ==== 2D Evaluation Axis ====
+The 2D evaluation axis used by all 2D outputs.
 ===== Nodal Inputs =====
 ==== Position (vector) ====
-==== MinDistance ====
+The position to find the closes point in the spline to. If this is not connected, then the current position provided by LightWave 3D is used.
-==== MaxDistance ====
+==== MinDistance (scalar) ====
-==== Function ====
+==== MaxDistance (scalar) ====
+These two defined the minimum and maximum range for the normalised outputs. The output will ne 0 at the minimum range and 1.0 at the maximum range.
+==== Function (function,scalar) ====
+This allows the shaping of the falloff for the normalised outputs.
 ===== Nodal Outputs =====
-==== Distance ====
+==== Distance (scalar) ====
-==== Normalised ====
-==== Position ====
+The distance of the current point to the closest point on the spline.
-==== Direction ====
+==== Normalised (scalar) ====
+The distance of the current point to the closest point on the spline but normalised into a 0..1 range using the Minimum and Maximum Distance.
+==== Position (vector)====
+The position of the closest point on the spline.
+==== Direction (vector)====
+The direction from the current point to the closest point on the spline, normalised.

 The same as above except that the evaluation is limited to a 2D plane, orthogonal to the 2D Evaluation Axis.
