dynamic reDirectPhysical

Implementation

var reDirectPhysical = shaderNode((inputs) {
  var lightDirection = inputs.lightDirection;
  var lightColor = inputs.lightColor;
  var directDiffuse = inputs.directDiffuse;
  var directSpecular = inputs.directSpecular;

  var dotNL = saturate(dot(transformedNormalView, lightDirection));
  var irradiance = mul(dotNL, lightColor);

  irradiance = mul(irradiance, pi); // punctual light

  addTo(directDiffuse, mul(irradiance, brdfLambert({diffuseColor})));

  addTo(
      directSpecular,
      mul(irradiance,
          brdfGGX({"lightDirection": lightDirection, "f0": specularColor, "f90": 1, "roughness": roughness})));
});
