示例1: euler2angle_axis
# 需要导入模块: from nibabel import quaternions [as 别名]
# 或者: from nibabel.quaternions import quat2angle_axis [as 别名]
def euler2angle_axis(z=0, y=0, x=0):
''' Return angle, axis corresponding to these Euler angles
Uses the z, then y, then x convention above
Parameters
----------
z : scalar
Rotation angle in radians around z-axis (performed first)
y : scalar
Rotation angle in radians around y-axis
x : scalar
Rotation angle in radians around x-axis (performed last)
Returns
-------
theta : scalar
angle of rotation
vector : array shape (3,)
axis around which rotation occurs
Examples
--------
>>> theta, vec = euler2angle_axis(0, 1.5, 0)
>>> print(theta)
1.5
>>> np.allclose(vec, [0, 1, 0])
True
