getDistanceAttenuation top-level property

dynamic getDistanceAttenuation

Implementation

var getDistanceAttenuation = shaderNode((inputs) {
  var lightDistance = inputs.lightDistance;
  var cutoffDistance = inputs.cutoffDistance;
  var decayExponent = inputs.decayExponent;

  return cond([
    and(greaterThan(cutoffDistance, 0), greaterThan(decayExponent, 0)),
    pow(saturate(add(div(negate(lightDistance), cutoffDistance), 1.0)), decayExponent),
    1.0
  ]);
});
