Unable to visualize OSI Data

[Alex7-K]

I installed Lichtblick and the osi-converter extension and loaded the example osi mcap file "only_osi_topic.mcap".
I am able to see the OSI structure in the rawdata panel but nothing in the 3D Panel.
Am i missing a step here?
Tried it on both Windows and Ubuntu 20.4, with the example file and an osi.txt->osi.mcap converted file.

You cought me in between transition. I will upload example files this week. Here a readme how you can create you own:

I did this on my phone while riding the bus. Feel free to commit/suggest changes and give feedback if this is enough information. The OpenMSL has all you need (for Linux users)

@Alex7-K Looks like the topic is missing in your screenshot. Does the extension show up in the list of installed extensions for you? After I install the asam-osi-converter extension, I can see the topic and if I click on the eye-button I can see the visualization. Without the extension, I can also only see the OSI raw structure and no topic appears.

But maybe, as @jdsika said, there could also be an issue with the structure of the mcap file. I don't know.

The example trace has a "not OSI compliant" topic name. That's why the extension ignores it and does not connect to it

Thanks for the support, we finaly found the issue.
We had some empty static objects in our osi structure, resulting in Lichtblick to not visualize OSI data at all.

Working with Python we've created a small Osi Mcap converter(input: .osi, .txt), we can share it if you like.

Ok, can you add the file as test case in an extra issue please?

It would be great if you would extend the c++ converter here with a python equivalent!
