How to use this tool

  1. Enter x, y, deadzone.
  2. Use consistent units shown beside each input. Run the calculation and review the assumptions below.

Try this example

{
  "x": 0.3,
  "y": 0.4,
  "deadzone": 0.2
}

Accuracy and scope

Linear radial remapping capped at one. Angle at zero input follows atan2 and is not a directional signal.
