Type: float

Quaternion.v¶

The direction vector.

Type: Vector

Methods Signatures

Quaternion.__init__(self) Returns a new Quaternion instance.

`Quaternion.GetMatrix(self)`	Derives a rotation matrix from the quaternion.
`Quaternion.SetMatrix(self, m)`	Derives quaternion values from a rotation matrix.
`Quaternion.SetMatrixNorm(self, m)`	Derives quaternion values from a normalized rotation matrix.
`Quaternion.SetHPB(self, hpb)`	Derives quaternion values from a HPB rotation.
`Quaternion.SetAxis(self, ax, ww)`	Sets the quaternion values directly.

Methods Documentation

Quaternion.GetMatrix(self)¶

Derives a rotation matrix from the quaternion.

Return type:	c4d.Matrix
Returns:	The rotation matrix.

Quaternion.SetMatrix(self, m)¶

Derives quaternion values from a rotation matrix.

Parameters:	m (c4d.Matrix) – The rotation matrix to set.

Quaternion.SetMatrixNorm(self, m)¶

Derives quaternion values from a normalized rotation matrix.

Parameters:	m (c4d.Matrix) – The normalized rotation matrix to set.

Quaternion.SetHPB(self, hpb)¶

Derives quaternion values from a HPB rotation.

Parameters:	hpb (c4d.Vector) – The HPB rotation.

Quaternion.SetAxis(self, ax, ww)¶

Sets the quaternion values directly.

Parameters:	ax (c4d.Vector) – The direction vector. ww (float) – The rotation angle.
