Check type-check for NDArray under Animate-Run-Update #137
Description
In animate.py
The frame type check is done against NDArray, which gives an error when passing a Rotation matrix for example. It works if changd to np.ndarray
Error
elif isinstance(frame, NDArray):fix
elif isinstance(frame, np.ndarray):Is this an error in animate.py or I need to fix something in my example?
Example
# imports
ax = plotvol3(new=True)
J = np.array([[ 2, -1, 0],
[-1, 4, 0],
[ 0, 0, 3]]);
orientation = UnitQuaternion(); # identity quaternion
w = 0.2 * np.array([1, 2, 2]);
dt = 0.05; # time step
def update():
global orientation, w
for t in np.arange(0, 10, dt):
wd = -np.linalg.inv(J) @ (np.cross(w, J @ w)) # (3.12)
w += wd * dt
orientation *= UnitQuaternion.EulerVec(w * dt)
print(type(orientation.R))
yield NDArray[orientation.R]
ani = tranimate(update(), ax=ax, frame='A', color='green');
