Error opening wrl files in Meshlab #13

Closed David-Estevez closed 3 years ago

David-Estevez commented 6 years ago

When I try to open any wrl file in Meshlab I get the following error:

Error encountered while loading file:
"/home/def/Repositories/teo-openrave-models/openrave/teo/models/0.0^cabeza_links.wrl"

File: /home/def/Repositories/teo-openrave-models/openrave/teo/models/0.0^cabeza_links.wrl
Error details: -- line 3 col 17: invalid NodeBodyElement

I am using Meshlab v1.3.2 64bit.

Replicated error opening these VRML V1.0 files using Meshlab v1.3.2 64bit on a different machine. It is however capable of opening the kinect VRML V2.0 file.

Was capable of opening the files with FreeCAD, would that be useful for you?

PS: Not sure if should be considered a bug in the scope if this repository, as openrave is capable of opening the files.

My original goal was to open them with Blender, but it failed. Then I tried with Meshlab and when it failed again, so I opened this issue.

@RaulFdzbis showed me then that this repo contains a .dae file with all the parts, which I was able to open in Blender, so I guess this is no longer an issue for me. :smile:

But if it is not too much work, I think it would be useful to export the original files to VRML V2.0 to avoid problems in the future.

For the record, the only COLLADA file in this repo was teo.dae, removed because of https://github.com/roboticslab-uc3m/teo-openrave-models/issues/32.

Done at https://github.com/roboticslab-uc3m/teo-openrave-models/commit/6dc56d8364ca8f2c615c0238a3d7426d50f68e2a. Successfully tested via OpenRAVE on Ubuntu 18.04 (OR 0.9.0 w/ Coin viewer) and Ubuntu 20.04 (OR 0.54.0 w/ OSG viewer).

Now I can open these .wrl files with Meshlab and convert them to .dae via meshlabserver -i part.wrl -o part.dae. Note FreeCAD is refusing to convert either format (VRML 1/2) to .dae via GUI.

@PeterBowman Thank you so much for this!

For further reference, how were these VRML 2 files generated?

PeterBowman commented 3 years ago

Sorry, I meant to add that but forgot it. FreeCAD was my choice: it allows you to open VRML1 files and export them to VRML2 afterwards.

My original goal was to open them with Blender, but it failed.

Turns out Blender cannot open the generated VRML2 (runs into something like https://developer.blender.org/T51334 IndexError: list index out of range while importing wrl file), however, it can open each individual .dae file generated currently at https://github.com/roboticslab-uc3m/teo-gazebo-models/tree/bbd7e33a2b0e6accdbaba5aef144fdbfa5b96136/models. : )
