Description
The LerpInverse
method calculates the linear parameter that produces the interpolant specified by value
within the range defined by from
and to
. This is essentially the inverse operation of linear interpolation (Lerp). The method can optionally clamp the result to the range [0, 1].
Usage
Use LerpInverse
when you need to determine the interpolation factor that would produce a given value between two endpoints. This is useful in scenarios where you have a value and need to find out its relative position between two other values.
The method signature is:
public static float LerpInverse(float value, float from, float to, bool clamp)
value
: The interpolated value for which you want to find the interpolation factor.
from
: The start of the range.
to
: The end of the range.
clamp
: If true, the result is clamped to the range [0, 1].
Example
// Example usage of LerpInverse
float start = 0.0f;
float end = 10.0f;
float value = 5.0f;
bool shouldClamp = true;
float t = MathX.LerpInverse(value, start, end, shouldClamp);
// t will be 0.5, as 5 is halfway between 0 and 10.
