3D visualize

[Yifan-debug]

Hi developer.

Thanks alot for the useful tools and sorry for keep bothering.

I need a 3D visualiza on my xenium dataset. Now I can correctly load my xenium data and check the transcripts point on 2D shape. I'm wondering if there is any plan to add the 3D visualize feature.

I also try to subset my sdata["transcripts"] based on the z value. however, after subset, I try to construct the sdata, it's not working. and showed error code. ValueError('Unable to coerce to Series, length must be 11: given 2')

Please also let me know if you have better recommendation on 3D visualization of xenium data.

HI @Yifan-debug,

Thanks alot for the useful tools and sorry for keep bothering.

no worries, feel free to ask 😊

I'm wondering if there is any plan to add the 3D visualize feature.

We are trying to hire a developer to focus exclusively on 3D but the process is slower than we hoped, so while of interest, for the moment 3D capabilities are limited. Some parts like read/write, transformations and spatial query are fully supported, but others require extra work: aggregation, visualization.

Please also let me know if you have better recommendation on 3D visualization of xenium data.

The good news is that since we designed our data model to reuse existing data structures, such as (dask) pandas DataFrames and Xarray DataArray, you can plug in the data directly to other viewer.

For instance I would suggest for instance to call scanpy for visualizing 3D points, or manually adding layers to napari for 3D points and 3D raster data.

I also try to subset my sdata["transcripts"] based on the z value. however, after subset, I try to construct the sdata, it's not working. and showed error code. ValueError('Unable to coerce to Series, length must be 11: given 2')

Can you please share the code that leads to the error you reported?

(for maintainers: the not 100% plotting related, but I moved it out of spatialdata-io)
