Convert OBJ to MODEL

Understanding OBJ and MODEL file formats

OBJ is a widely used 3D geometry definition file format developed by Wavefront Technologies. It stores 3D model data such as vertices, texture coordinates, normals, and faces, and is supported by most 3D graphics applications. OBJ files are plain text and can be easily edited or exported from various 3D modeling tools.

MODEL is a more generic term and can refer to several proprietary or application-specific 3D model formats. For the purpose of this conversion, MODEL often refers to the Apple Model I/O (.model) format, used in Apple’s AR and 3D applications, or to other software-specific formats. Always confirm the target application’s requirements before converting.

How to convert OBJ to MODEL

Converting an OBJ file to a MODEL file typically requires specialized software, as MODEL is not a universal standard. The process may vary depending on the target application. Below are general steps using Apple’s Xcode and Model I/O tools for .model files:

1. Open Xcode on your Mac.
2. In your project, right-click the asset catalog and select Import.
3. Choose your OBJ file and import it.
4. Xcode will automatically convert the OBJ to the .model format for use in ARKit or SceneKit projects.

Alternatively, you can use the Model I/O command-line tools provided by Apple:

1. Open Terminal.
2. Use the usdconvert or assetutil command to convert OBJ to MODEL, e.g., assetutil convert input.obj output.model.

Best software for OBJ to MODEL conversion

• Xcode (macOS) – Best for Apple’s .model format, integrates with ARKit and SceneKit.
• Apple Model I/O tools – Command-line utilities for batch conversion and automation.
• Blender – Can import OBJ and export to various formats, but may require plugins for MODEL export.

Tips for successful conversion

• Check the target application’s documentation to confirm the required MODEL format.
• Ensure your OBJ file is clean and free of errors before conversion.
• Test the converted MODEL file in your target application to verify compatibility.
