OBJ What is an OBJ File? (Alias Wavefront Object Explained)

The OBJ file format is a widely used open standard for storing and exchanging 3D geometry, originally developed by Wavefront Technologies. Unlike binary formats, OBJ files use a human-readable text format, making them highly compatible across 3D modeling, animation, and rendering software.

Key Features and Benefits of OBJ Files

Multiple Named Objects: OBJ files can contain multiple 3D objects within a single file, each organized with individual names, ideal for complex 3D scenes and asset management.
Surface Materials and Textures: OBJ files support detailed surface definitions, including transparent materials and texture mapping, enabling realistic 3D model rendering.
Quad and Triangle Support: Geometry in OBJ files can include both quads and triangles. During OBJ file conversion, quads are automatically divided into triangles to ensure compatibility with applications that only support triangular meshes.
File Size Considerations: As a text-based format, OBJ files tend to be larger than binary formats like SKP or 3DS, which can impact loading speeds and storage requirements for complex models.
