Quaternion class

Note

A class that represents the four elements x, y, z, and w of a quaternion.

class definition

class Quaternion
{
     public float x, y, z, w;

     public Quaternion()
     public Matrix GetMatrix()
}

Quaternion makeQuaternion(float x, float y, float z, float w)

global function. Generate a quaternion by specifying 4 elements x, y, z, w.

Quaternion makeQuaternionMul(Quaternion a, Quaternion b)

global function. Multiplies two quaternions and returns the result as a new quaternion.

Quaternion makeQuaternionXRotation(float rotateRadian)

global function. Returns the quaternion rotated by rotateRadian around the x-axis.

Quaternion makeQuaternionYRotation(float rotateRadian)

global function. Returns the quaternion rotated by rotateRadian around the y-axis.

Quaternion makeQuaternionZRotation(float rotateRadian)

global function. Returns the quaternion rotated by rotateRadian around the z-axis.

Quaternion makeQuaternionEuler(float x, float y, float z)

global function. Generates a quaternion from the triplet of Euler angles x, y, z.

public Quaternion()

Creates a quaternion instance with x, y, z elements set to 0 and w element set to 1.

public float x

The x component of the quaternion.

public float y

The y component of the quaternion.

public float z

The z component of the quaternion.

public float w

The w component of the quaternion.

public Matrix GetMatrix()

Returns the quaternion as a 4x4 matrix.
