comfyui-lerp-node

A simple math node that performs linear interpolation between a base range and a mapped range.

SimpleLERP

Maps an input value from an input range [in_min, in_max] onto an output range [out_min, out_max]:

t      = (value - in_min) / (in_max - in_min)
output = out_min + t * (out_max - out_min)

Found in the node browser under the math category as Simple LERP.

Inputs

| Name | Type | Default | Description | |-----------|---------|---------|--------------------------------------------------------------------| | value | FLOAT | 0.0 | The value to map. | | in_min | FLOAT | 0.0 | Lower bound of the input range. | | in_max | FLOAT | 1.0 | Upper bound of the input range. | | out_min | FLOAT | 0.0 | Lower bound of the output range. | | out_max | FLOAT | 1.0 | Upper bound of the output range. | | clamp | BOOLEAN | False | If true, hold the result within the output range instead of extrapolating. |

Output

| Name | Type | Description | |---------|-------|----------------------------| | value | FLOAT | The interpolated result. |

Notes:

• With clamp off, inputs outside [in_min, in_max] extrapolate beyond the output range.
• Inverted ranges (e.g. out_min > out_max) are supported.
• If in_min == in_max, the result is out_min (no division by zero).
