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 Spline Primitive or the Spline Preferences.

Selects the spline used by this node.

Switches all evaluation to world coordinates.

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.

The 2D evaluation axis used by all 2D outputs.

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.

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.

This allows the shaping of the falloff for the normalised outputs.

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

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.

The position of the closest point on the spline.

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.
