Hello,

I would like to evaluate the import for some gltf and glb files in open cascade. I saw that in TKRWMesh module there is an interface for reading gltf (not sure if glb is suported). Is there any example in open cascade sources of its usage? Can you provide some code snippet for that? Looking at the ImportExport mfc sample it looks like a good hook to test the gltf import there (the example already support BREP, STEP and IGES import). Thanks in advance.

If you need just evaluating glTF reader - you may check CAD Assistant or Draw Harness:

pload XDE VISUALIZATION
ReadGltf D PathToGltf.glb
vinit
XDisplay -dispMode 1 D
vfit

And yes, glb files are supported.

glTF writer is relatively a new feature - it was available in OCCT development branch for a while, and now available in OCCT 7.5.0 release.
