Description
Description of bug / unexpected behavior
When playing animations of SpiralIn for ArrowVectorField in 3d scenes, several frames of pure color will be generated. The exact color is unsure; I have met blue and yellow.
Expected behavior
No pure color frame is generated when creating ArrowVectorField under the previously described situation.
How to reproduce the issue
Code for reproducing the problem
class BugTest(ThreeDScene):
def construct(self):
field = ArrowVectorField(lambda p: np.array([0, 0, 1.0]), x_range=[-4, 4], y_range=[-4, 4])
self.set_camera_orientation(phi= 60 * DEGREES, theta=45 * DEGREES)
self.play(SpiralIn(field), run_time=2)
