Inverse Linear Mapping

What It Does

Maps a value from one numeric range to another, similar to range mapping. It takes a value within a source range and finds the equivalent value in a target range, maintaining the same relative position.

Inputs

Name	Description	Type	Required
value	The value to transform	Number	No
inMin	The minimum of the source range	Number	No
inMax	The maximum of the source range	Number	No
outMin	The minimum of the target range	Number	No
outMax	The maximum of the target range	Number	No
clamp	Whether to restrict the result to the output range	Yes/No	No
precision	Number of decimal places to round to	Number	No

Outputs

Name	Description	Type
value	The transformed value in the new range	Number

Inverse Linear Mapping Example

How to Use It

1. Drag the Inverse Linear Mapping node into your graph.

2. Set "value" to the number you want to transform (e.g., 0.5).

3. Define your source range with "inMin" (e.g., 0) and "inMax" (e.g., 1).

4. Define your target range with "outMin" (e.g., 0) and "outMax" (e.g., 100).

5. Choose whether to clamp the result to the output range.

6. Set the "precision" for decimal rounding (default is 2).

7. Run the graph—with the example values, your output will be 50.

Tips

• Ensure inMin and inMax are different values to avoid division by zero.

• The output range can be reversed (e.g., outMin=100, outMax=0) to invert the mapping.

• When clamp is enabled, the output will never exceed the output range boundaries.

Use Cases

• Responsive Design: Map screen dimensions to appropriate element sizes.

• Data Visualization: Convert raw data values to pixel coordinates for display.

• Animation Control: Transform timing values into position, opacity, or scale values.

• Normalization: Convert values from different scales into a common range (often 0-1).
