Internal Float32Array storage for quaternion components
ReadonlyclassThe class name identifier
ReadonlywThe w component (real quaternion basis)
ReadonlyxThe x component (i quaternion basis)
ReadonlyyThe y component (j quaternion basis)
ReadonlyzThe z component (k quaternion basis)
Gets the component value at the specified index.
Index (0=x, 1=y, 2=z, 3=w)
The component value at the given index
Calculates the dot product between this quaternion and another.
The other quaternion
The dot product result
Converts the quaternion to a flat array of numbers.
Array containing [x, y, z, w] components
Checks if this quaternion is a dummy/invalid quaternion.
True if the quaternion is dummy, false otherwise
Compares this quaternion with another quaternion for equality within a tolerance.
The quaternion to compare with
Optionaldelta: numberOptional tolerance value for comparison (default uses system epsilon)
True if quaternions are equal within tolerance, false otherwise
Compares this quaternion with another quaternion for strict equality.
The quaternion to compare with
True if quaternions are exactly equal, false otherwise
Calculates the magnitude (length) of the quaternion.
The magnitude of the quaternion
Calculates the squared magnitude of the quaternion. More efficient than length() when only comparison is needed.
The squared magnitude of the quaternion
Converts the quaternion to Euler angles.
A new vector containing Euler angles (x=pitch, y=yaw, z=roll)
Converts the quaternion to Euler angles and stores the result in the provided vector.
The output vector to store the Euler angles
The output vector containing Euler angles (x=pitch, y=yaw, z=roll)
Returns a string representation of the quaternion.
String representation of the quaternion
Returns an approximate string representation of the quaternion with limited precision.
Approximate string representation
Transforms a 3D vector by this quaternion rotation and stores the result in the output vector.
The vector to transform
The output vector to store the result
The output vector containing the transformed result
Immutable quaternion interface representing a rotation in 3D space. Quaternions are a mathematical notation for representing rotations and orientations. They consist of four components: x, y, z (imaginary parts) and w (real part).
