Inverse Lerp Node
Description
Returns the linear parameter that produces the interpolant specified by input T within the range of input A to input B.
Inverse Lerp is the inverse operation of the Lerp Node. It can be used to determine what the input to a Lerp was based on its output.
For example, the value of a Lerp between 0 and 2 with a T value of 1 is 0.5. Therefore the value of an Inverse Lerp between 0 and 2 with a T value of 0.5 is 1.
Ports
| Name | Direction | Type | Description |
|---|---|---|---|
| A | Input | Dynamic Vector | First input value |
| B | Input | Dynamic Vector | Second input value |
| T | Input | Dynamic Vector | Time value |
| Out | Output | Dynamic Vector | Output value |
Generated Code Example
The following example code represents one possible outcome of this node.
void Unity_InverseLerp_float4(float4 A, float4 B, float4 T, out float4 Out)
{
Out = (T - A)/(B - A);
