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
