Urban Eye 3D – JOSM 3D Viewer Plugin

Zkir · November 28, 2025, 9:25pm

Strange. It never crashed before.

Could you please provide me with osm file? Or coordinates of bbox?

SimonHarms · November 29, 2025, 10:11pm

Sorry can’t reproduce it. Today everythin was fine

SekeRob · November 30, 2025, 8:03pm

Never a fail here, but I do tag roof:orientation to tell if the hip is on the short (across) or is on long side (along). Then I use the KindaHacked plugin extension’s H shortcut to add the roof:direction.

@SekeRob, why do you need roof:direction if you have already set roof:orientation?

SekeRob · December 1, 2025, 9:13am

Orientation along/across only tells if on the long or short side, does not tell which of the two short/long sides… direction will. Strictly only direction would be enough for roof types like side hipped and skillion, but I’d like to be complete.

Hi, could it be possible, that saltbox has the wrong shape?

Zkir · December 2, 2025, 5:40pm

I would say that there is no real consensus about roof:shape=saltbox. Other wiki-pages describes describes this shape differently, and there are different opinions even in single bug report.

Urban Eye just follows rendering of F4 here.

Lumikeiju · December 2, 2025, 6:27pm

Besides the very-WIP OSM Wiki: OSM-4D proposal, where are the conflicts? (ref: OSM Wiki: Tag:roof:shape=saltbox#Common_tagging_mistakes)

The existing roof:shape=saltbox rendering by the plugin is definitely incorrect.

roof:ridge=yes could be used to indicate the location of the ridge, as I have (experimentally) done here and here:

In its absence, just default to the ridge being at the ⅓rd mark along the edge.

Let roof:direction=* work just like roof:shape=gabled, but with the long side of the roof sloping down in that roof:direction=*.

SimonHarms · December 2, 2025, 6:41pm

Perhaps I should just use two skillions …

Lumikeiju · December 2, 2025, 6:55pm

Unnecessary complication - that requires two additional building:part=* areas, for something that should just be represented as a single tag on the main building=*.

SimonHarms · December 4, 2025, 10:23pm

I don’t know if the ticket system is for plugin creators, too…
I got the “crash” again.

€dit:
like @ivanbranco proposed:

github.com/Zkir/UrbanEye3D

JOSM tells randomly that Urban Eye 3D crashed when uploading the data.

I would rather open an issue here:

Zkir · December 4, 2025, 11:58pm

Osm-file or coordinates are highly needed!

Zkir · December 7, 2025, 11:15am

The bug is fixed in 1.6.1

@SimonHarms, please pay attention to validation results. You examples contain a lot of broken geometry, it may impact generation of 3d models negatively.
