Visualisation of point data

[jwagemann]

We currently use meteograms to do this, is there a better way?

Blender has a really powerful point cloud system I use for datasets. It can handle really large amounts of data.

This dataset is 6million points.

and you can get up close and personal with them.

and since it's blender you can scale and adjust them accordingly.

This allows you to plot two variables. For this dataset I plotted the color as depth and the physical size of the points as abundance/density.

This data can also of course be animated.

But how to get the data into blender? Does it support netCDF files natively?

[TheJeran]

Not natively, but Blender has a Python front end. So you can load it into Blender via some fairly rudimentary scripting. I use Xarray

To focus on one location, the BlenderGIS plugin can also be quite useful. Perhaps there can be a pipeline that connects with this plugin. https://github.com/domlysz/BlenderGIS

@TheJeran Is there some kind of tutorial/script for this? I can not find any good resource ❓

@chongshenng This looks amazing 👀
