New 3D examples..

There is something new in Kathmandu, Nepal:

Thank you guys, good job!


Please check the mapping before giving links to such a mess:

most roof:height are missing so it gives different rendering between projects (on F4Maps most of wall are screwed because generated roof:height is higher than heigh-min_height)

roof:colour=#cococo i think using “0” would be better for a color than “o”

height=0.1 on building outline with higher parts (outline height should be the max height of every parts)

many dupplicated nodes, overlapping buildings and other JOSM Warnings

Well, cmif4, the best possibility for us to teach the people there.
They are very happy to achieve this results and enthusiastic.

What they need is feedback from us.

I don’t understand how it has been pushed to osm, there are self-intersecting polygons, a big mess with S3DB tags, partial taggings etc.

It look weird in both Kendzi3D and F4Maps (I didn’t checked osm2world but i can predict it won’t look nice).

I don’t blame the contributor if he is learning S3Db but he could at least check the result inside a 3D renderer.

I contacted him by private message to ask him to check and fix his rendering with Kendzi3D and redirect him on this topic to ask if he needs help.

Great cmif4!
I have recently unfortunaltely no time for teaching. Normally I like it.
Thank you!


It is not perfect but this is what is being made

most roof:height are missing
This is because roofs have been digitized separately than buildings. Since roofs cover much larger area than the building, atleast twice as large. So roofs are made as buildings without the lower part.

generated roof:height is higher than height - min_height
This is because there is no support for trapezoidal roof, Pyramidal roof are made by giving higher value for roof:height and then another structure is used to cover up the extra part. Since values are not exact, there are some mismatches.

This has been corrected.

many dupplicated nodes, overlapping buildings and other JOSM Warnings
duplicated nodes have been corrected, but there are no overlapping buildings.

Look at this example from polish OSM user marcin_b:

Great 3D model!

The data are too big for f4-maps. Use Kendzi3D or opensciencemap instead.
Rendered images:

a colleague made a quick fix for it to display

a lot of building:part are outside the building outline and so won’t display.

same problem for the ceiling, it’s too big compared to outline so it’s not included in the building. also outline includes a hole in the middle, explaining the loss of middle stuff!

for the part that looks like ceiling, it’s the outline leftovers, use building:part=no to remove it.

looks like there are the same problems on opensciencemap

insane level of details though ! :slight_smile:

looks good now ! :slight_smile:

Which editor has been used for that kind of tagging?

He used JOSM with Kendzi3d for preview.

Good Example from India, Mysore Palace:

Good job :slight_smile:

Good job from Malaga:


Dome of Siena. Still in progress:

Looks really good.

I noticed that a lot of buildings (including the last one) are not connected to some high level relation. Is it just because of “work in progress”? I’m working on my generator for Unity3D and it is quite important to group all parts by one relation so that I can create one Unity’s GameObject instead of hundreds. This is major performance optimization f and also this way I can interact with the building as single mesh which is quite important from business logic. For example, I like this one:

With my generator, I’m able to create one mesh here instead of hundreds.

We’ve had a mapping party at Grozny city recently. And here’s a bit of results:

Dear Felis Pimeja,
fantastic model, great job in Grozny!

Dear eis_kalt, that´s true, the Siena Cathedral is still in progress.
Could you be so nice and add your hint into the subpage:
Maybe a link to an other Page with examples showing what happens with 3D model without building relation.
