About GLTF Format
glTF (GL Transmission Format) is the 'JPEG of 3D' — an efficient, open format for 3D scenes and models. Optimized for real-time rendering, it is the standard for web-based 3D content, AR/VR, and game assets.
About STL Format
STL (Stereolithography) is the standard file format for 3D printing. It represents 3D surface geometry as a mesh of triangles, without color or texture information. Supported by virtually all 3D printing software and services.
