# pyobjc-framework-ModelIO — Wrappers for the framework ModelIO on macOS

License: permissive · Maintenance: active · Downloads: 656.2K/mo

## What it is and what it does

This package wraps Apple's ModelIO framework, making it accessible from Python on macOS. ModelIO is part of Apple's graphics and media infrastructure, typically used for loading and processing 3D models and meshes. The wrapper translates between Python and Objective-C, allowing developers to call ModelIO APIs directly from Python code.

The package depends on pyobjc-core for the bridging infrastructure and pyobjc-framework-Cocoa and pyobjc-framework-Quartz for related macOS framework access. It is actively maintained and supports modern Python versions (3.10 through 3.15, including free-threading variants). Documentation is minimal in the package itself; users are directed to Apple's official ModelIO documentation and PyObjC's general translation guides.

Use it for:

- Load and parse 3D model files on macOS using Apple's native ModelIO framework from Python.
- Process mesh data and geometry in Python applications that run on macOS and need native performance.
- Integrate 3D model handling into macOS desktop applications written in Python.
- Access ModelIO's mesh optimization and analysis features for graphics pipelines on macOS.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides Python bindings to Apple's ModelIO framework on macOS, enabling access to 3D model loading, mesh processing, and related graphics capabilities through a Python interface.

Yes, if you are developing on macOS and need to work with 3D models or mesh data using Apple's native framework. The package is actively maintained, permissively licensed, and supports current Python versions. Install friction is moderate due to macOS-only wheels and system dependencies, but that is inherent to the framework it wraps. Not applicable on non-macOS platforms.

## Install

pip install pyobjc-framework-modelio
uv add pyobjc-framework-modelio
poetry add pyobjc-framework-modelio

## Installing pyobjc-framework-ModelIO

Before you install: Medium install friction due to platform and architecture specificity—wheels are macOS-only (universal2 binaries for various Python versions from 3.10 onward). Maintenance is active with a recent release (3 days old) and steady repository activity.

License in practice: MIT license is permissive; you may use, modify, and distribute this package freely with minimal restrictions, making it suitable for both open-source and commercial projects.

Quickstart:

pip install pyobjc-framework-modelio

import ModelIO
# Access ModelIO framework classes and functions through the ModelIO module

macOS only; requires Python 3.10 or later; depends on pyobjc-core, pyobjc-framework-Cocoa, and pyobjc-framework-Quartz.

Verify before relying:

- Whether the package includes or requires separate installation of Apple's ModelIO framework headers or system libraries.
- Specific ModelIO framework capabilities exposed by this wrapper (e.g., supported 3D formats, mesh operations).
