Animating a mayavi points3d plot

Question

I\'m trying to make a video of the trajectories of particles. However, somehow my scene never updates. Here\'s a very simple example:

from __future__ import          


        

Answer 1

Just change to:

...

    for (x, y, z) in zip(xs, ys, zs):
        print('Updating scene...')
        plt.mlab_source.set(x=x, y=y, z=z)
        yield

...

you don't even need the f.scene.render(), according to documentation mlab_source.set guarantees the refresh.

Also since shape of your data doesn't change you don't need to use mlab_source.reset.

I also tested and works fine.

Answer 2

Have you tried mlab_source.reset? It works even when the length of the x, y, and z arrays are changed.

In your case, it'll be: plt.mlab_source.reset(x=x,y=y,z=z).
