Reusable UI components for viewing and authoring USD files.

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. All widgets in this library use separate models and views and a standardized set of signals to trigger updates makeing it easy to customize views and build applications a la carte. Also, since these widgets are meant to be consumed anywhere and by everything, they will be designed to work in PyQt4/PyQt5/PySide/PySide2. Our long term goal is to break up the remaining parts of usdview and add them to this collection as well, such that it can be used to build usdview-like applications that are more easily customized.

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 additional editing capabilities:
• switch variant
• add reference
• add Xform
• sub-layer selector: 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
• hydra viewport

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
