Understanding the rotation direction or handedness in three.js

It has come to my attention that when I perform rotation around the Z axis on my model, as shown below:

model.rotateZ(rotatedAngle * Math.PI / 180);

The rotation appears to be in a counter-clockwise direction around the axis.

  • Can this observation be confirmed?
  • Is there any official documentation addressing this behavior? Despite my efforts, I have been unable to locate relevant information.
  • Is there a way to adjust this rotation direction?
  • What is considered the best approach for handling rotations in this scenario?

Answer №1

In Three.js, the default rotation follows the right-handed system, where counter-clockwise is the norm. For a comprehensive guide on rotation rules, check here.

Left signifies the left-handed system (clockwise), while right represents the right-handed system (counter-clockwise)

Therefore, adding something to your angle results in a counter-clockwise rotation, while removing something leads to a clockwise rotation.

function rotate(){
    mesh1.rotation.z += 0.01;  // rotates counter-clockwise
    mesh2.rotation.z -= 0.01;  // rotates clockwise
}
