VRMLLoader parse error

[d-packs]

I have two sample wrl files, both do not load correctly (tested in Firefox and Chromium). Error is Uncaught Error: THREE.VRMLLoader: Parsing errors detected.

To test I have replaced the model in examples/webgl_loader_vrml.html with my models.

Test files:

File 1 wrl.zip File 2 .wrl.zip

Three.js version

0.115.0

Browser

• [x] Chrome
• [x] Firefox

OS

• [x] Linux (Manjaro Linux - Arch based - kernel 5.6)

Your files are VRML 1.0 files which are not supported by the loader. You have to use VRML 2.0.

Unfortunately, I can't even import the files into Blender or Meshlab since I wanted to test a conversion to 2.0.

[d-packs]

thank you for the clarification.

[Mugen87]

Please let me know if you find a way to convert them from 1.0 to 2.0. Such a tool could be useful in future support cases.

@Mugen87 It seems the version check needs to occur earlier.

@Mugen87 For converting VRML1 to VRML2:

• this has two CLI tools (and the links are still working): http://www.interocitors.com/polyhedra/vr1tovr2/
• there is also Okino PolyTrans, although I haven't used it since 2011: https://www.okino.com/conv/imp_iv.htm

@cecilemuller Thank you!

I've used the converter at (http://www.interocitors.com/polyhedra/vr1tovr2/) to generate v2 files. But the file won't display at all. No parsing error this time. The file is being retrieved by the script., no CORS error or anything.

Here are the converted files test-modelsvrml-v2.zip

I looked at the converted files in Vrmlpad (to check for code errors) and BS Contact (to check for visual errors), but they look valid, the conversion worked.

Perhaps it's just a Viewpoint position issue (given Contact zooms out to fit the bounding box of the geometry when there is no Viewpoint in the scene).

Ah, the problem is that VRMLLoader does not process the Collision node yet. I think we can easily fix this by treating such nodes like other grouping nodes.
