What is an OBJ file?
OBJ is a widely supported 3D model format that stores geometry and, via a companion .mtl file, material and texture references. It's a common interchange format between 3D applications.
What is a GLB file?
GLB is the binary form of glTF — a single self-contained file holding 3D geometry, materials, and textures. It's the modern standard for sharing 3D models on the web and in AR.
