The OBJ (Wavefront) format is one of the most universal and oldest 3D formats, supported by virtually all 3D modeling software. Converting OBJ to GLB/glTF lets you display your 3D models on the web or in real-time applications.
Launch Eyemesh and open your OBJ file: drag and drop the file into the window, or use File > Open (Cmd+O). Make sure the .mtl file and associated textures are in the same folder as the .obj file. Open the full folder so Eyemesh loads materials automatically.
Inspect your model in the 3D view. Check that textures and materials display correctly. If textures are missing, use the Texture Manager to reassign them manually.
Click the export icon in the toolbar, select the GLB or glTF format, choose a save location, and confirm. The file is ready to embed on the web or in a real-time 3D application.
OBJ (Wavefront) is an open format for describing 3D geometry. It stores vertices, faces, normals, and UV coordinates. Materials are defined in an associated .mtl file, with textures stored as separate image files. Its simplicity makes it a universal exchange format, though it does not support animations.
glTF (GL Transmission Format) is an open Khronos Group format, often called the "JPEG of 3D". Its binary version GLB packages geometry, PBR materials, textures, and animations into a single file. It is the standard format for web 3D (Three.js, Babylon.js, model-viewer) and cross-platform AR/VR experiences.
