The components in usdview are good reference, but they’re purpose built for the usdview application and are implemented in a way that makes them difficult to extract. We need widgets that provide similar functionality that we can use ad-hoc throughout our pipeline.
- make it easy to build standalione usdview-like applications, or integrate with client plugins (maya, katana, etc)
- long term, build a complete replacement of usdview
- separate models and views
- standardize signals/slots between widgets
- support PyQt4/PyQt5/PySide/PySide2
This is a first look to get feedback. This repo may go away!
- prim outliner: view prim hierarchy
- similar to the outliner in usdview, but built on an MVC design
- also includes editing capabilities:
- switch variants
- add references
- add Xforms
- sublayer view: view sub-layers and choose the current target
- layer editor: view usd ascii for current layer
- variant set editor: display and create variants and variant sets
- stage signaler: convert stage notifications into Qt signals
- prim property editor: view and edit properties/attributes of a prim
- hydra viewport: display changes to the stage in realtime
First, install the dependencies:
pip install -r requirements.txt --user
Note that this assumes you have pyside/2 or pyqt4/5 installed. If you don't, then run the following (and cross your fingers), or use homebrew:
pip install PySide --user
You'll also obviously need to make sure that you've built USD and placed the pxr python package on the PYTHONPATH.
To test it out:
python usdqt/app.py /path/to/file.usd
