Methods Signatures

Quaternion.__init__()

Returns a new Quaternion instance.

Quaternion.GetMatrix()	Derives a rotation matrix from the quaternion.
Quaternion.SetMatrix()	Derives quaternion values from a rotation matrix.
Quaternion.SetMatrixNorm()	Derives quaternion values from a normalized rotation matrix.
Quaternion.SetHPB()	Derives quaternion values from a HPB rotation.
Quaternion.SetAxis()	Sets the quaternion values directly.

Methods Documentation

Quaternion.__init__(self)

Returns a new Quaternion instance.

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.
