OBJ
A traditional 3D model file format developed by Wavefront Technologies. It stores only geometry information and does not support complete packaging of materials and animation.
Timeline (last 90 days)
The traditional Web 3D development chain is: concept design → modeling (Blender, etc.) → exporting glTF/OBJ → writing Three.js loading and interaction logic → repeatedly tuning with the performance panel, among which modeling and tuning are the most time-consuming and most dependent on professionals
Common 3D asset formats (such as OBJ, FBX, GLTF) are essentially snapshots of geometric results, storing vertex, face and material data, and modifying one shape often requires regenerating the entire file, whereas executable 3D code describes the rules and parameters for generating geometry.
OBJ is an old format from the 1990s that only supports geometry and basic material references, and does not support animation or PBR; STL stores only the vertex coordinates and normals of triangles, with no color, UV, or materials, and is the common language of the 3D printing field, readable by all slicing software (Cura, PrusaSlicer, Bambu Studio).
InstructMesh's ability to integrate with existing toolchains (such as exporting STL, OBJ, and STEP formats) directly affects its practicality.
