Math.reverseLerp Method
Returns the linear interpolation parameter t for the value y.
This method is static.
Parameters
- a
-
Type: Number
The value to interpolate from.
- b
-
Type: Number
The value to interpolate to.
- y
-
Type: Number
The value to find the parameter for.
Return Value
Type: Number
Parameter for this interpolator that corresponds to x.
Remarks
Performs linear interpolation for values in the domain [0, 1] to the range [a, b].
That is, given the points (0, a) and (1, b) this solves for t in the point (t, y).
