====== Spline Proximity (node) ======

This node computes the distance of the current point/shading spot to the closest point on the selected spline.

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) ====
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.
==== MinDistance (scalar) ====
==== 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 (scalar) ====

The distance of the current point to the closest point on the spline.

==== 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.

==== 2D Distance (scalar) ====
==== 2D Normalised (scalar) ====
==== 2D Position (vector)====
==== 2D Direction (vector)====
The same as above except that the evaluation is limited to a 2D plane, orthogonal to the 2D Evaluation Axis.
