3D file guides
Practical notes for working with 3D model files.
These guides explain the decisions behind common 3D file workflows: when to use GLB instead of glTF, why STL loses material data, and how to reduce model size without destroying visual quality.
GLB vs glTF
Understand the difference between the binary and JSON forms of glTF before choosing a web format.
How to reduce GLB file size
Reduce geometry, texture and animation weight while keeping a model useful for real-time viewers.
3D file format guide
Compare GLB, glTF, STL, OBJ, PLY, 3MF and FBX by what each format preserves.
