An OBJ file is a standard 3D image format that is used to represent 3D geometry. It is widely supported by various 3D graphics applications and is often used for exchanging 3D models between different software. However, the context provided does not specifically mention OBJ files. Instead, it focuses on USD (Universal Scene Description) file formats, which are used extensively in Apple's ecosystem for 3D assets and spatial computing.
Here are some key points about USD file formats mentioned in the context:
- USDA: An ASCII format that can be read as plain text, making it suitable for collaborative files where multiple people might be making edits.
- USDC: A binary format that is more efficient for storing large amounts of data such as geometry.
- USDZ: A zip format that packages all dependencies for an asset, such as textures, into an internal file structure, making it great for publishing and distributing assets.
For more detailed information on these formats, you can refer to the session Optimize your 3D assets for spatial computing.
