Support Point Cloud

[akaszynski]

Looking at pythreejs, it seems like it should be possible to add a point cloud. Any hints for getting this added? I'm fine with submitting a PR.

My bad, it's in ipygany, just not documented:
https://github.com/QuantStack/ipygany/blob/9181b7d5408ee0304f50ae3fd22beab45076224a/ipygany/ipygany.py#L426-L433

Would be nice to have docs and a from_pyvista method. Mind if I leave this open to remind myself?

Almost there. Is there any way to change the size of the points?

Thanks for opening an issue!

Unfortunately not yet. There are some limitations in the ThreeJS Materials I am using in ipygany (see mrdoob/three.js#18153). I will try to allocate some time this week for this and other ipygany stuffs and release it :)

I'm working on supporting ipygany in pyvista/pyvista#1239, and adding features like point sizes and wireframes would be really helpful. I realize that much needs to be added under the hood to support this, but I'd really like to be able to mirror many of the features available in vtk.js to ipygany since threejs is a bit more performant. A few features would be super valuable like:

• wireframe representation
• opacity
• lighting control
• Unbuffered arrays (enables smooth shading and seems more efficient)

Please let me know if I can help out.

Any update on this?

Note that pyvista now supports using pythreejs: https://docs.pyvista.org/user-guide/jupyter/pythreejs.html

You can use a ton of features that are unavailable in ipygany.

Correct, I'm using it already. 😉
