Pointcloud support

[haehn]

Hi,

Would it be possible to also wrap encoder->EncodePointCloudToBuffer ? Did you try it already?

Thanks so much!

It's definitely possible, and functionality I want to have. But I haven't tried it yet, and I'm not sure how much time I'll have to in the near future. If you want to give it a shot by all means! I imagine the code would be quite similar to encode_mesh in DracoPy.h

[haehn]

Thanks! I will take a look!

Started working on this this weekend.. close to releasing a new version whenever I have a few hours to refactor and release

I did some work on this last week: https://github.com/haehn/DracoPy maybe its helpful

Encoding works already

[manuel-castro]

That's funny, we ended up doing almost exactly the same thing, whoops 😅. Sorry I hope you didn't spend too much time on this.

In this branch decoding and encoding works: https://github.com/seung-lab/DracoPy/tree/point_cloud_support

I just want to refactor it to reduce the duplicate code (working with meshes and point clouds are quite similar) before releasing it

Thank you for your help!

[haehn]

That is funny. Thanks! I do need generic point cloud support - not only x,y,z data. Will you include that as well?

[manuel-castro]

I'm planning on adding support for Generic, Texture, and Color attributes next after this. Not sure when exactly I'll be able to since I can only really work on this nights and weekends. Like before, feel free to give it a try.

I added support for generic encoding and for sequential point cloud encoding by modifying your code. Not the cleanest but it works :)

Cool beans! By the way I refactored the code and published a new version to PyPI, so v0.0.14 is live with the point cloud support

[william-silversmith]

Hi @haehn, I couldn't tell from this discussion if all the features you wanted were included in 0.0.14. Would you still like to proceed with the PR?

Any update on this? DracoPy in this repo doesn't seem to read in color data from point clouds.
