3d Slicer Draft USD Support

Intro

USD support is the fundamental prerequisite for having a direct connection between 3d Slicer and Omniverse.

Note

The code here is a rough proof of concept for DataHack Hackathon by lablab.me

How to use this draft:

1. Copy utils folder to your project folder (next to .mrml file)

   

2. Install dependencies inside 3d slicer, by the following code.

   this is done once..

   import sys; import subprocess; subprocess.run([sys.executable, '-m', 'pip', 'install', 'usd-core']); subprocess.run([sys.executable, '-m', 'pip', 'install', 'unicodedata'])

3. Export and convert model, by Running the following code in 3d slicer's python shell.

   USD file name is the same as the project folder name.

   import sys; sys.path.append("{}/utils".format(slicer.mrmlScene.GetRootDirectory().strip("/")))
   
   from export_usd import export_usd
   export_usd()
