Relaunching the 3D Model Repository

[Ayush_Dhar_Dubey]

Hello @karlos

As always, thanks again for your continued testing and feedback on OSMgo with the latest 3DMR release, your feedback really helps move things forward!

@karlos

SOLVED: The last one, Hafenkran Kocks seems to have lost its colours the obj/mtl was converted to glb. (OSMgo)

Yes, that was indeed an issue with automated model conversion. Thanks to the efforts of @tordanik and @lonvia, this specific case has been fixed. There may be other models affected in a similar way, if you happen to notice them, please report them either on the community forum or via GitHub issues.

3D Model Repository - Liceul Sfintii Kiril si Metodii Model is broken, missing walls

I believe this one isn’t actually broken. What’s happening is that Three.js’ default renderer hides objects beyond a cutoff distance from the camera perspective. Since this model has unusually large dimensions, parts of it disappear once they’re too far away from the perspective, which is relatively smaller on the model’s scale. Since I am relatively new working on ThreeJS, would you happen to know any fix for this, by chance??

@karlos

In the model data always 0.00: Triangle Density: 0.00 triangles/m3

No; It’s not always zero. The value is rounded to two decimal places, so with very large bounding boxes, the density drops into very small numbers (like 0.0000034 triangles/m³) which round down to 0.00. A dynamic unit system depending on the value is on the to-do list.

@karlos

We could have Categories that need to be selected while upload. Like single-use OR multi-use, point-claud OR mesh-model, building OR art OR … other. And the homepage may have a way to select this options as filters to list models.

very nice suggestion, would you like to open a feature request for this on the GitHub repo so we can track it properly??

@karlos

In Altdorf is a model tagged by “3dmr:id”, not “3dmr”. Which one shall we use?

The correct tag is 3dmr. Seems to be fixed, thanks again to @tordanik.

@karlos

I would like to have a way to show all values of the info request, like offset in the UI

As part of our discussions during GSoC program, we decided to phase out support for offset(origin), translation, scale and rotation fields. Instead, contributors are encouraged to upload models aligned correctly with world coordinates and directions. To help with this, the upload form now includes a small preview with direction helpers.
It’s generally more reliable to fix models locally in tools like Blender before upload. I believe perhaps @tordanik is looking into the direction of fixing all models relying on such fields…

@karlos

It seems, the orientation of the models changed +180 degrees, but not all?

That’s also a consequence of the obj → glb conversion don’t know what to say on this…

@karlos

3dmr could also have a link to Overpass to find all tagged instances of all/one 3dmr object:

We actually did implement this one right after your initial feedback, please find the new
3DMR tag: 3dmr=nn
hyperlink at the top of the model panel.
