Quaternion methods

Static methods

Quaternion.identity

This function returns the identity quaternion. Meaning no rotation would be applied to the Object, Vector, other Quaternion, etc.

const Q = Quaternion.identity();
Q; // Quaternion [ 1, 0, 0, 0 ]

Quaternion.fromEuler

Returns a Quaternion corresponding to a euler angle rotation in radians

const Q = Quaternion.fromEuler(0, 0, 0);
Q; // Quaternion [ 1, 0, 0, 0 ]

Quaternion.lookAt

const Q = Quaternion.lookAt(new Vector(), new Vector(1,1,1));
Q; // A quaternion with a rotation looking from a towards b

Quaternion.lookAtOptimized

WARNING: This function is unstable and hard coded. This is not meant to be used for general purposes. Only use if you know what you are doing. Otherwise, please use Quaternion.lookAt

This function takes in an array for the heading it should point towards, and returns a Volts.Quaternion

const Q = Quaternion.lookAt([0,0,1])

Instance methods

Quaternion.copy

This copies the values of a Quaternion and returns a new one

const Q = Quaternion.identity();
// The values of the original Q Quaternion remain unchained
// In spite of the operations applied to the new Quaternion
Q.copy().mul(Quaternion.fromEuler(1.57,0,0));
