Interpolation

The Multi Cubic Lerp takes in any number of tangent points (TangentPointFloat or TangentPointDouble), and a lerp value to travel from start to finish through all of them. This returns the value of a specific point using that lerp value.

The types needed are found using the Pack Tangent Point nodes.

This differs from the Multi Bezier Curve node as it attempts to solve a problem with curves, utilizing Cubic Spline Interpolation.

This node is the multi version of the Cubic Lerp node.

Inputs

Lerp (float)

The travel lerp point from start to finish (per lerp input).

Operands (float)

The lerp inputs.

Outputs

* (Pseudo-Generic)

Returns the value of a specific point along this lerp value.
