About GLTF

GLTF is an open 3D file format developed by the Khronos Group. It uses JSON to store scene information and can reference external files for textures and binary data. Known as the "JPEG of 3D," glTF is ideal for real-time rendering and online 3D content.

About STL

STL is one of the most widely used formats in 3D printing. It represents the surface geometry of a 3D object using a mesh of triangles. STL files do not store color or material data but are ideal for rapid prototyping and additive manufacturing.
