Linearly interpolates between Left and Right by the factor Alpha. At Alpha = 0 the result equals Left; at Alpha = 1 the result equals Right. Values of Alpha outside [0, 1] extrapolate beyond the endpoints. Use this to blend between two float parameters — for example fading a volume or blending between two speeds based on a normalized input.

Configuration

Left

The value returned when Alpha is 0.

Right

The value returned when Alpha is 1. Defaults to 1.

Alpha

The interpolation factor. Typically in [0, 1].

Result

Left + (Right - Left) * Alpha.
