Quat
This a python binding to the C++ class Mantid::Kernel::Quat.
-
class mantid.kernel.Quat((object)self)
Quaternions are the 3D generalization of complex numbers. Quaternions are used for roations in 3D spaces and often implemented for computer graphics applications.
-
__init__((object)self) → None :
Construct a default Quat that will perform no transformation.
- __init__( (object)self, (float)w, (float)a, (float)b, (float)c) -> None :
- Constructor with values
- __init__( (object)self, (V3D)src, (V3D)dest) -> None :
- Construct a Quat between two vectors
- __init__( (object)self, (V3D)rX, (V3D)rY, (V3D)rZ) -> None :
- Construct a Quaternion that performs a reference frame rotation.
The initial X,Y,Z vectors are aligned as expected: X=(1,0,0), Y=(0,1,0), Z=(0,0,1)
- __init__( (object)self, (float)deg, (V3D)axis) -> None :
- Constructor from an angle(degrees) and an axis.
-
imagI((Quat)self) → float :
Returns the ith imaginary component
-
imagJ((Quat)self) → float :
Returns the jth imaginary component
-
imagK((Quat)self) → float :
Returns the kth imaginary component
-
len((Quat)self) → float :
Returns the ‘length’ of the quaternion
-
len2((Quat)self) → float :
Returns the square of the ‘length’ of the quaternion
-
real((Quat)self) → float :
Returns the real part of the quaternion
-
rotate((Quat)self, (V3D)v) → None :
Rotate the quaternion by the given vector
