# Precompiled macOS Python Modules for Pixar's USD Library (Version 18.09)
2+
3+
This archive contains precompiled macOS Python modules for Pixar's USD library, and a set of sample scripts that demonstrate how to generate usd files.
4+
5+
## Python Bindings
6+
7+
This binary library was compiled using version 18.09 of [the public USD Github repository](http://openusd.org) with the following build script arguments (see USDPython/README.md for further details):
8+
9+
python USD/build_scripts/build_usd.py --build-args TBB,extra_inc=big_iron.inc --python --no-imaging --docs --no-usdview --build-monolithic USDPython
10+
11+
To start using USD in Python, set your PATH and PYTHONPATH variables as follows (replace `<PATH_TO_USDPYTHON>` with the path to this USDPython folder):
12+
13+
export PATH=$PATH:<PATH_TO_USDPYTHON>/USD
14+
export PYTHONPATH=$PYTHONPATH:<PATH_TO_USDPYTHON>/USD
15+
16+
You should then be able to easily inspect the content of any text or binary .usd file or a .usdz archive usding `usdcat`, e.g.:
17+
18+
usdcat samples/assets/island.usdz
19+
20+
21+
## Samples
22+
23+
The `samples` folder contains a set of simple scripts that focus on different aspects of writing USD data, such as geometry, materials, skinning and animation.
24+
Each script generates a .usdc and a .usdz file in the `assets` subfolder, and also prints the generated .usd file's content.
25+
26+
| Script | Purpose |
27+
| ------ | --- |
28+
| `simpleMesh.py` | creates a cube mesh |
29+
| `simpleTransforms.py` | builds a scene graph of several objects and sets (animated) translate, rotate, and scale transforms |
30+
| `simpleMaterial.py` | creates a simple PBR material |
31+
| `meshGroups.py` | creates a cube mesh with two mesh groups and assigns each a separate material |
32+
| `texturedMaterial.py` | creates a cube mesh and assigns it a PBR material with a diffuse texture |
33+
| `complexMaterial.py` | creates a cube mesh and assigns it a more complex PBR material with textures for normal, roughness and diffuse channels |
34+
| `skinnedMeshAnimation.py` | creates an animated skinned cube |
35+
36+
