[MERGED] glTF format support?

[paullee]

Recently noted the glTF format...

Arch has Web Export, any plan to support glTF?

Dropped into this article :-

Why we should all support glTF 2.0 as THE standard asset exchange format for game engines https://godotengine.org/article/we-shou ... me-engines

... glTF 2.0: What makes it great?


Don't understand the technicality, seem useful at all?

gltf indeed seems very cool, it's under my radar for some time... However, all apps I have seen that import/use gltf also take more common mesh formats such as obj or stl. Since FreeCAD won't export any UV / texturing stuff anyway, there wouldn't be any real advantage to export gltf directly.

Better to wait until there is a nice gltf i/o library out there that we can use

Indeed, I only note IfcOpenShell can convert to Collada and then to glTF.

For usecase, only thinking it may be easier to have a FC model, with ArchTexture Fruti works on probably, shown on a mobile / smartphone easier:)

Would wait to see!

Any update on this?

Meanwhile maybe at try to export to blender and then export to GLTF ?

Feedback welcome

As long as FreeCAD has no native export, one of these methods:

1. Export as STEP -> Import into CAD Assistant from Opencascade -> Export glTF
2. Use the python library cqparts :

Code: Select all

>>> import cqparts
>>> cqparts.Assembly.importer('step')('myfile.stp').exporter('gltf')('myfile.gltf')

As long as FreeCAD has no native export, one of these methods:

I created a wiki page to document this: gITF

Is there anyway to import gITF in to FC yet, using a workaround?

Use OCC 7.5 There is support for reading and writing glTF 2.0 The name implies only writing but here it is mentioned occt also reads glTF

Nice. Maybe we can open a FR to add gITF native support in FreeCAD ?
Thoughts?
