tinyusdz 0.9.9rc5

Tiny, dependency-free USD/USDA/USDC/USDZ loader + Tydra scene access, with NumPy-friendly zero-copy arrays (CPython abi3 wheel).

tinyusdz

Python bindings for TinyUSDZ, a small USD/USDA/USDC/USDZ loader and authoring library that does not require a Pixar OpenUSD install.

• Single abi3 wheel per platform for CPython 3.11+.
• No NumPy dependency; zero-copy buffer protocol support when NumPy is present.
• No Pixar USD install required.
• Includes Tydra render-scene conversion for renderer-friendly mesh, material, texture, light, camera, animation, and skeleton data.

Install

pip install tinyusdz

Quick start

import tinyusdz

stage = tinyusdz.load("scene.usdz")
for prim in tinyusdz.traverse(stage):
    print(prim.type_name, prim.name)

mesh = stage.get_prim_at_path("/World/Mesh")
points = mesh.get_attribute("points").value

# Zero-copy NumPy view (optional — NumPy is not required)
import numpy as np
arr = np.asarray(points)
print(arr.shape, arr.dtype)

scene = tinyusdz.tydra.convert_to_render_scene(stage)
print(len(scene.meshes()), len(scene.materials()))
