Is there any way to advance time in offline website viewer, and keep it in one plot #19

Hi, I'm currently interested in having a mesh, and deforming it with time. The examples I've seen (using libigl with meshplot) , seem to not show the mesh object changing with time, but instead show snapshots of the mesh taken at a specific time.

What I'd like to do is have a mesh at the start of the simulation, run the simulation, and be able to see it deform in real time in the viewer. I can't seem to find any functionality for it in the source code, does it exist? Can you think of a workaround I could do instead? Thanks

Hi, you can update your plotted objects with the function p.update_object(vertices=new_v). A possible example of a plot that you describe then looks like this

import meshplot as mp
import time

p = mp.plot(v, f)

for i in range(100):
    v_new = run_simulation_step(v, f, ...)
    p.update_object(vertices=v_new)
    v = v_new
    time.sleep(0.1) # depending on how long your simulation step takes you want to wait for a little while

in the same vein, i'm curious about updating the wireframe of the plot for this purpose
