Cubic Lerp

Lerp

Interpolation

The Cubic Lerp takes in 2 tangent points (TangentPointFloat or TangentPointDouble), and a lerp value to travel from start to finish. 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 Bezier Curve node as it attempts to solve a problem with curves, utilizing Cubic Spline Interpolation.

Inputs

From (Pseudo-Generic)

The start point of this lerp.

To (Pseudo-Generic)

The end point of this lerp.

Lerp (float)

The travel point from start to finish.

Outputs

* (Pseudo-Generic)

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