LensDistortionPass

const p = new LensDistortionPass({
  // +ve=barrel -ve=pincushion
  distortion: new Vector2(0, 0),
  // focus coords      
  principalPoint: new Vector2(0, 0),
  // focal length 
  focalLength: new Vector2(1, 1),
  // skew angle in rad
  skew: 0
});

p.distortion.set(0.1, 0.1)      // +ve=barrel 
p.distortion.set(-0.1, -0.1)    // -ve=pincushion
p.principalPoint.set(0.5, 0.0)  // shift focus
p.focalLength.set(0.5, 0.5)     // get closer
p.skew = Math.PI / 4            // skew 45d
