MSH at a glance
MSH
Gmsh developed MSH as its native mesh exchange and storage format for geometry-to-mesh workflows, finite element modeling, and post-processing, and later evolved the format across multiple major versions while preserving legacy compatibility.
GLB at a glance
GLB
glTF and GLB grew after earlier interchange formats proved too heavy for many web and runtime delivery tasks, which is why Khronos now positions glTF as a transmission/runtime format.

When to use each format
When to use MSH
- design authoring
- review handoff

FAQs
Why convert MSH to GLB?
Choose GLB as target when you need a single-file 3D asset for web viewers, AR previews, real-time applications, product visualization, or engine import with minimal packaging friction.
What changes when converting MSH to GLB?
Convert to GLB when you need a single-file 3D asset for web viewers, AR previews, real-time applications, product visualization, or engine import with minimal packaging friction. It is often the best target for deployment-ready 3D delivery. Use GLB when compact transport and modern runtime compatibility matter more than human-readable source structure.
What should I review after converting MSH to GLB?
After conversion, review these destination checks: Open converted output in web 3D engines and verify behavior on real samples; Compare output against the expected precise quality profile; Not every authoring workflow keeps all rich edit semantics in GLB.
How can I keep quality stable in MSH to GLB conversion?
Run representative samples, keep settings deterministic, and monitor these risks: Often used as a delivery target more than a master working format; Not every authoring workflow keeps all rich edit semantics in GLB; Validate destination compatibility before large-batch conversion.
