Real time 3D map using WebGL

Could you check rendering of this element: https://www.openstreetmap.org/way/362550347
http://demo.f4map.com/#lat=53.5559229&l … phi=-9.167

?

Is there a update of this list ?
Especially there where we can make the difference ;-

@marek wow that's unexpected !! Looking into it now

@Jakka I'm not sure what you want... http://wiki.f4map.com/wiki/3D_Render should be approximately up to date for what's handled in f4map

I was looking for example factory, gate lorry gates, doors, windows, to give my building more details. And how to do it easy

Some buildings....

http://demo.f4map.com/#lat=50.7763070&l … phi=-89.84

http://demo.f4map.com/#lat=50.7751027&l … phi=48.991

How to lower the ground level with -1.5 m only where the lorry drive backwards again the gates?

thx

shrddr · 2015-08-07 08:37:20

i'm pretty sure you can't alter the ground level in any way

Cactusbone · 2015-08-11 11:00:54

Nice !! http://demo.f4map.com/#lat=35.6245482&l … phi=-1.719

marek kleciak · 2015-08-12 10:34:00

Something is going wrong. All roof shapes are flat...

Cactusbone · 2015-08-13 10:15:23

we were having a problem yesterday. it should have been fixed around 12:30 CEST

marek kleciak · 2015-08-13 11:22:16

OK, it works now.
Implement area:highway in your model. See: http://osmapa.pl/w/area/?lat=52.10564&l … m=19&ol=BP
Specification:
http://wiki.openstreetmap.org/wiki/Prop … treet_area

Daily comes now about 1000 new areas...

About that problem:

levels=9, min_level=5 -> no walls + a roof at level 4
However, if you change roof shape to pyramidal on these parts, everything works as expected.

- still no fix?

sorry we had no time to look into it I'll try doing it during this week

[EDIT] looks like a bug with dome roof without roof:height or roof:levels . basically for roof, we try to calculate the diameter of the base building to draw a nice rounded roof.
Adding height should fix it for now. we're trying to fix it anyway. FYI, for pyramidal we apply a default 4m height.

Might be a similar problem here: glitched rendering of gabled roof. Changing to pyramidal fixes it.

shrddr · 2015-09-01 09:04:32

Also, can we force a refresh for a specific building? Waiting until the next day after every little change is really frustrating.

Cactusbone · 2015-09-01 10:32:27

should be fixed now ! thanks for the report (with nice and useful details, it really helped debug).

caching is done per "tile" so you can't force a specific building it's 12h of cache right now.
I understand it can be really frustrating. I'll try to think of something.

Doesn't work even though I explicitly specified roof:height

Cactusbone · 2015-09-02 09:48:53

@shrddr
roof:height would only have fixed dome
we'll look into it.

I have found some problems with 3D objects in Warsaw on F4, but it doesn't seem to me to be a data issue (at least Kendzi3D shows them properly):
1. http://www.openstreetmap.org/relation/3217013 -> http://demo.f4map.com/#lat=52.2424786&l … 54&zoom=19
2. http://www.openstreetmap.org/way/34614532 -> http://demo.f4map.com/#lat=52.2491393&l … phi=94.252

Cactusbone · 2015-09-02 16:15:27

@kocio
Metropolitan : be careful, relation#75539 is also marked as building
way 238660071 is marked as building with a height = 0.1. I think this is to avoid volume rendering. for f4map you can use building:part=no for that. height on the building should always be the real height of the building
That being said, I don't know what's causing the bug, we'll look into it too

For the library, there are no parts starting from the ground. It seems like you're trying to use the outline for rendering this time. You must use a part for that too, and set the correct height on the outline (which is not rendered at all since it's fully covered by parts)

Thanks! I will pass the message to the people dealing with those 3D objects.

***

I have also more general 3D-related problem. I try to render fountains on osm-carto, but it seems that current definition (amenity=foutain) does not cover such things as nozzles and other objects being a part of fountain (for example lights and the artworks). For example in this fountain:

http://www.openstreetmap.org/way/79738429

the name shows that "fountain" is this whole structure, but it's tagged just as a water and individual nozzles are tagged as amenity=fountain. My current tagging idea goes like this:

https://github.com/gravitystorm/openstr … -137197243

but maybe looking from 3D perspective you have more ideas to try?

Cactusbone · 2015-09-03 16:27:04

@shrddr ok we fixed it. thanks again for the report !

xmd5a · 2015-09-05 21:26:18

Something changed some time ago and now most buildings in Moscow, Red square (and Kremlin) are gone
http://demo.f4map.com/#lat=55.7521494&l … eta=43.236
http://www.openstreetmap.org/#map=18/55.75264/37.62351
They are tagged as relation type=multipolygon+building=yes + type=multipolygon + building:part=yes

Cactusbone · 2015-09-07 11:03:05

It seems there's a problem with elevations activated. try without them

EDIT : fixed with elevations! thanks for the feedback

@Cactusbone

Apologies for hijacking this thread, but I've been trying to get in touch with f4map.com since we'd like to know what the licensing options are to integrate the map into a custom, commercial application for GPS tracking - to no avail. Is there anything you can do to get me in touch with the right people?

You can email me: johan (dot) dams (at) wrdsystems.co.uk

marek kleciak · 2016-05-31 09:56:20

Dear F4 team,
I go crazy because of differences of the interpretation of 3D tagging between you and Kendzi3D which is the only one existing tool which shows in real time what happens during 3D attributation of tags.

An good example could be this: http://demo.f4map.com/#lat=27.7151026&l … phi=-14.61

https://www.openstreetmap.org/way/201223707

I would suggest a meeting to clarify the differences.
I have also suggestions regarding bottom parts of building:part elements.
I started to describe this here:

http://wiki.openstreetmap.org/wiki/Roof_position

Cactusbone · 2016-05-31 10:30:22

Difference is impressive indeed... We'll try to find what's wrong.

building:roof handling seems different, when we see building:roof, only the roof part is rendered, not the building below it. this enables to have a floating roof, which seems to be what you want here

Central part : It looks like we're inheriting roof:shape from the building to the parts.
Either make the bottom dome a building:part, or specify roof:shape for every part.

I don't know what properties kendzi inherit from building.

Interesting roof proposal I like how it enables to make arches, but it's not straightforward to think of the roof as beneath the building. and you need another part to have a normal roof above.
