What is OBJ in 3D modeling file formats?

OBJ is a text-based 3D file format for storing geometric data (vertices, faces, textures) and exchanging models between software. It’s widely compatible with tools like Blender or Maya, often paired with MTL files to include material details (e.g., colors, texture links). Common uses include basic game dev, 3D printing, or sharing simple models—ideal for universal readability without complex features. If you need a simple, cross-software format, OBJ is reliable due to its ease of use and broad industry support.
