Derive Node Reference
Lerp Node
Description
The Lerp node performs a linear interpolation between two values A and B, based on Alpha. Alpha determines the fraction or weight of each input on the blend. If Alpha equals 1, the output equals B and if it equals 0, the output equals A. For values between 0 and 1 the linear interpolation is performed calculating the weighted blend of A and B.
Sample Tree
Properties
| Property Name | Property Type | Description |
|---|---|---|
|
A |
Float |
Uniform float to be used as input for the lerp operation (only available if the A-input is not connected). |
|
B |
Float |
Uniform float to be used as input for the lerp operation (only available if the B-input is not connected). |
|
Alpha |
Float Slider |
Uniform interpolation value or blend weight by which the linear interpolation is performed (only available if the B-input is not connected). |
Inputs
| Input Name | Allowed Data Types | Description |
|---|---|---|
|
A |
Float, RGBA |
Input that takes the first texture for the lerp operation. |
|
B |
Float, RGBA |
Input that takes the second texture for the lerp operation. |
|
Alpha |
Float, RGBA |
Input that take the texture used as interpolation value or blend weight by which the linear interpolation is performed pixelwise. |
Outputs
| Output Name | Data Type | Description |
|---|---|---|
|
Result |
Float if all inputs are of type float, otherwise RGBA. |
Outputs a linear interpolation between A and B, whereas the value of every channel for every pixel is lerped between A and B based on Alpha. Alpha can be different for each pixel, if the Alpha input is connected, otherwise Alpha will be uniform for all pixels (see properties). |
