USD in rhino and possible interaction with OWL

Grasshopper
1

Hi,

I’ve watched https://youtu.be/12an8H9xj7c?si=pPb3qQ6uJuhNg9A_ and I’m also working inside Blender to try out different capabilities of the USD format.

I managed to create an USD file with pxr library in jupyterlab that has a semantic layer (see attached file)

smart_building.rar (678 Bytes)

With rdflib and pxr I can extract brick and Bot from the USD file.

I’m not a rhino user yet, but I have a few questions about rhino working with USD.

As seen on this picture, I cannot acces the data from the USD in Blender.

How does rhino handles that ? Is it possible to access the meta-data from an USD direct from rhino ?

This new format creates a lot of new possibilities in term of cooperation and PLM.

Hi Hans -

That appears to be a file in the json format. There are third party plug-ins for Grasshopper to deserialize those to extract the information that you require. JSwan comes to mind → https://www.food4rhino.com/en/app/jswan

Hey Wim,

Serializing and de-serializing is not a problem anymore, I can do that with python easily.

I was thinking of having a parametric workflow in Rhino and use the data and relations to drive the model and make multiple scenario’s.

The only benefits from Blender are the possibility to visualize the data and also edit hierarchy and properties of the USD file.

When it comes to electrical studies I cannot use Blender in an efficient way. I would like to overcome these limitations and use full power of my workflow.

I’m sorry but it isn’t json
