Free online OBJ to USDZ converter

Understanding OBJ and USDZ file formats

The OBJ file format is a widely-used 3D model format that represents 3D geometry, including the position of each vertex, the UV position of each texture coordinate vertex, vertex normals, and the faces that make each polygon. It is a simple data-format that represents 3D geometry alone, without any representation of color, texture, or other common 3D model attributes.

The USDZ file format, on the other hand, is a 3D file format developed by Apple and Pixar. It is a zero-compression, unencrypted zip archive that can contain multiple files, including textures, animations, and other 3D data. USDZ is particularly popular for augmented reality (AR) applications on Apple devices, as it allows for easy sharing and viewing of 3D content.

How to convert OBJ to USDZ

Converting an OBJ file to a USDZ file involves translating the 3D geometry and any associated textures or materials into the USDZ format. This can be done using various software tools and converters.

Best software for OBJ to USDZ conversion

One of the best tools for converting OBJ to USDZ is Reality Converter by Apple. This tool is specifically designed to convert 3D models into the USDZ format, making it ideal for developers and designers working with AR on Apple platforms.

To convert using Reality Converter, follow these steps:

• Open Reality Converter.
• Use the File → Open menu to load your OBJ file.
• Adjust any settings as needed, such as materials or lighting.
• Use the File → Export → USDZ option to save your file in the USDZ format.

Another option is Blender, a free and open-source 3D creation suite. With the help of plugins, Blender can export models to the USDZ format.

To convert using Blender, follow these steps:

• Open Blender and import your OBJ file using the File → Import → Wavefront (.obj) menu.
• Install a USDZ export plugin if necessary.
• Use the File → Export → USDZ option to save your file in the USDZ format.
