Add 3d markers for 3d scatter plots (3d glyphs)

[emmanuelle]

At the moment the markers of a Scatter3d trace are 2d objects which do not scale when zooming in/out. It would be great to have spherical or cubic markers which would be genuinely 3d and be similar to the cone trace.

@emmanuelle would you like to dedicate a new issue for scalable 2d markers as well?

Is #3682 related?

No that's not related.

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 a while, 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. Alternatively, if it's a request for tech support, please post in our community forum. Thank you - @gvwilson

Bumping this issue. Scale information is completely lost due to lack of constant sizing. This is very important for my use case

hi @gdebrun2 - I've moved it to our backlog, but realistically it will be months before we get to it - we would welcome a PR from the community, and would be able to review that much more quickly.
