Display edges lines for Mesh3d

[emmanuelle]

See https://community.plot.ly/t/show-edges-of-the-mesh-in-a-mesh3d-plot/33614, I don't know if the geometry of the edges is already computed and it would be a question of adding an edges or lines attribute to mesh3d, or if it's more complicated than that.

gl-mesh3d module kind of supports this:

What should be the API for this?

[emmanuelle]

Cute :-). Maybe an edge or line object? Is it possible with gl-mesh3d to visualize both the faces and the edges?

[archmoj]

I simply passed lines instead of triangles in a quick prototype to make use of this part of gl-mesh3d code: https://github.com/gl-vis/gl-mesh3d/blob/master/mesh.js#L492-L510

I am not sure if this should be a new trace/mode with lineColor...

@emmanuelle just noticed this wonderful post at https://plot.ly/~empet/15416 by @empet which also includes a wireframe plot using scatter3d.
Thought we should mention this neat approach in reply to those community questions.

Here is a demo: http://requirebin.com/?gist=37a8df8ace4ecafa010f
Seems like an interesting feature to add.

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
