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 utility functions
makeQuaternion(float, float, float, float)
Quaternion makeQuaternion(float x, float y, float z, float w)
global function. Generate Quaternion by specifying 4 elements x, y, z, w.
makeQuaternionMul(Quaternion, Quaternion)
Quaternion makeQuaternionMul(Quaternion a, Quaternion b)
global function. Multiplies two quaternions and returns the result as a new quaternion.
makeQuaternionXRotation(float)
Quaternion makeQuaternionXRotation(float rotateRadian)
global function. Returns the quaternion rotated by rotateRadian around the x-axis.
makeQuaternionYRotation(float)
Quaternion makeQuaternionYRotation(float rotateRadian)
global function. Returns the quaternion rotated by rotateRadian around the y-axis.
makeQuaternionZRotation(float)
Quaternion makeQuaternionZRotation(float rotateRadian)
global function. Returns the quaternion rotated by rotateRadian around the z-axis.
makeQuaternionEuler(float, float, float)
Quaternion makeQuaternionEuler(float x, float y, float z)
global function. Generates a quaternion from the triplet of Euler angles x, y, z.
Constructor
Quaternion()
public Quaternion()
Creates a Quaternion instance with x, y, z elements set to 0 and w element set to 1.
member variables
float x
public float x
The x component of the quaternion.
float y
public float y
The y component of the quaternion.
float z
public float z
The z component of the quaternion.
float w
public float w
The w component of the quaternion.
methods
GetMatrix()
public Matrix GetMatrix()
Returns the quaternion as a 4x4 matrix.
