lerpUnclamped

@JvmStatic

Performs an unclamped linear interpolation between two vectors a and b by an interpolant t.

The interpolant t is not clamped. This means if t is outside the [0.0, 1.0] range, the function will perform extrapolation.

When t = 0.0, this function returns a.
When t = 1.0, this function returns b.
When 0.0 < t < 1.0, the return value is a point on the line segment between a and b.
When t < 0.0 or t > 1.0, the return value is a point on the infinite line defined by a and b, extrapolated beyond the segment.

The calculation is a + (b - a) * t.

The interpolated or extrapolated Vector3.

The starting vector (value when t=0).

The "ending" vector (value when t=1).

The interpolation/extrapolation factor. It is not clamped.
