Mesh3d alphahull is broken

[cstenkamp]

In version 4.14.3, alphahull algorithm for Mesh3d seems broken - the examples at https://plotly.com/python/3d-mesh/ also don't render.

Minimal example (from the docs):

import plotly.graph_objects as go
import numpy as np

pts = np.loadtxt(np.DataSource().open('https://raw.githubusercontent.com/plotly/datasets/master/mesh_dataset.txt'))
x, y, z = pts.T

fig = go.Figure(data=[go.Mesh3d(x=x, y=y, z=z,
                   alphahull=5,
                   opacity=0.4,
                   color='cyan')])
fig.show()

Thanks for the report.
This is now addressed at plotly.js level: https://github.com/plotly/plotly.js/releases/tag/v2.10.1 so the fix would be available in the next plotly.py release.

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for several years, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Thanks for your help - @gvwilson
