Linear Interpolation (LERP) returns a value between two others at a point of linear scale.

Rotation = From + (To - From) × Amount

Input:

• From: The value to transition from.
• To: The value to transition to.
• Amount: How far to transition.

Output:

• Rotation: The value between the From and To input, at a linear scale (defined by Amount input).

Example

The most common use case is to smoothly transition from one rotation to another.

Every frame, the block rotates 5% (0.05) of the way from its initial rotation to its destination.
