The new release should finally provide a way to let users change the reference system of 3DCityDB instance via the Importer/Exporter GUI. I think, the database operation panel is a suitable place. I would create another tab called SRS
.
Regarding the code I would reuse the DatabaseSrsComboBox and put two (labesl +) text fields, one checkbox and one button beneath it. Each element in one row. For the text fields I would use the same terminology than in the org.citydb.modules.database.gui.preferences.SrsPanel class (impexp-client module). Not sure, if I should add the check button as well, but probably it makes sense to do so.
I've already added the functions calls to the UtilAdapters. That was pretty easy. But the GUI development might take up more time. Have I missed something?
Is it possible to create glTF from 3DcityDB on demand? For now we can only export by export tool once in a while. So if data in the database changes, we have to reexport changed models once again.
Ideally it could be a database function that returns glTF-encoded data for a requested object.
Could you add a total number to that generation window and a percentage of completion? This is taking a long time and I would like to see how far it's from completion.
Image below shows what it currently looks like when generating spreadsheet. This is just a minor improvement, but it would be much appreciated.
When CityGML objects have more than one named appearance theme the material data from the surface_data can be overwritten with default colors. I have a fix that I'll check in as soon as I find out how...
Hello I am Fadel.
I am currently trying to visualize a dataset of shape file multipatch into Cesium using 3D web client.
I exported the shp multipatch to CityGML using fme. It was successfull.
After that I exported the GML into KML/GLTF using BBox option and with the tiling option was clicked. It was succesfull.
However when I try to call the data in the web browser, It only shows a blue line of border (which was Bbox) with no 3d model loaded in the box. I have tried to zoom in but I still found no model.
Then I checked the Console in the browser, There are warnings telling that this kind of ID model with .GLTF format is not found.
I checked the root directory and trace the ID. I found that the file with such ID only in .DAE format.
I tried to search any file with GLTF format in the TILES directory. I found none.
Please help me to resolve this issue.
Thank you.
Hey,
because i use a elevation Modell i have to move extruded buildings in height. But it only use building height. I think the altitude parameters only works for geometry export.
so, absolut and offset should be add to extruded export
The Importer/Exporter exports GLTF-models without texture coordinates.
Apparently, the Collada files a malformed, so the collada2gltf tools ignores the texture coords.
Example:
<effect id="_tex4666_eff">
<profile_COMMON>
<newparam sid="_tex4666_surface">
<surface type="2D">
<init_from>_tex4666_img</init_from>
</surface>
</newparam>
<newparam sid="_tex4666_sampler">
<sampler2D>
<source>_tex4666_surface</source>
</sampler2D>
</newparam>
<technique sid="COMMON">
<lambert>
<emission>
<color>0.0 0.0 0.0 1.0</color>
</emission>
<diffuse>
<texture texture="_tex4666_sampler" texcoord="TEXCOORD"/>
</diffuse>
</lambert>
</technique>
<extra>
<technique profile="GOOGLEEARTH">
<double_sided>0</double_sided>
</technique>
</extra>
</profile_COMMON>
</effect>
According to the schema specs (https://www.khronos.org/files/collada_spec_1_4.pdf, site 225), when texcoord="TEXCOORD"
is used, there also needs to be a line like this later on:
< bind_vertex _input semantic=" TEXCOORD" input_semantic=" TEXCOORD " />
But no such line exists in the generated Collada-file.. This causes the collada2gltf tool to just drop the TexCoord attribute in the GLTF-file. To fix this, either remove the texcoord="TEXCOORD"
attribute or add the bind_vertex node in.
Hi
i am trying to understand how things work with 3dcitydatabase, so i am installing the importer/exporter and the 3d web client...
Is there a forum where i can make some questions?
I would like to know if i can use a command line process in order to install the importer/exporter, as far as i understand it requires a graphical interface... Am i wrong?
Im using a remote virtual machine, equipped with Ubuntu 16.04, and i can only use the terminal...
I have downloaded this project, but i cannot find "3dcitydb-impexp.jar" as stated in the 3DCityDB manual starting from page 202 - chapter 5.8.
thank you for your help and support
Dear all,
this is not a 3DCityDB issue, but I would like to check with you how we can solve a problem in our conversion process.
We completed and tested our workflow to convert CityGML to BGLTF (automatically starting from the import in 3DCityDB) in order to ingest 3D datasets in CesiumJS and visualize them on the globe.
Everything works fine, but we have some problems in the visualization, in particular with 3D objects without textures.
The CityGML model source has no appearance/theme and the export to COLLADA (and then to GLTF) creates flat shaders.
It seems that there is no algorithm to calculate the normals of the surfaces (as you can check form the image).
Do you have any idea on how to solve this issue?
On Debian, it's possible to create a postgres user without password, the authentication is done directly with the unix credential (ex: if the user "citydb" starts pgsql and the postgres user "citydb" exists, then the
user can have acces to his database directly).
The java importer/exporter imposes to enter a db password, the password should be optional in this case.
Hello,
I'm trying to use the command line Importer/Exporter. I saved the project from the GUI as "myconf.xml".
When i save myconf.xml on the desktop i get an error message Failed to find config file 'filepath'
When i save myconf.xml in the same folder with the Importer/Exporter and use relative path i get an error message Failed to read project settings file 'filepath'
I run the command line tool from the Importer/Exporter installation path.

Is there a way to run a database import via command line arguments or some other programmatic method? I would like to deploy an xml file to a cloud server & DB along with the importer/exporter tool and then have the import happen there rather than tie up my own machine.
Apologies if this would be better served in a different 3Dcitydb repo.
Hi all, I have a project, https://github.com/stirringhalo/osm2citygml, which is the process of going from OSM, to 3D, to CityGML for 3DCityDB. Latest version isn't committed just yet, but for the most part, it works quite well minus some coordinate translation + axes rotations issues.
However, I do have an issue which appears to be a precision issue related to imports/exports. On the left of the picture is 1WTC first in Cesium, exported as GLTF and the right is the original CityGML, when viewed in FME. All the way along, the OBJs and CityGML look good with no visible gaps except for when viewed as exported tiles. I haven't tried with WFS or exporting a CityGML and double checking.
I'm not sure, but I suspect perhaps the issue is in import and data precision.
If you want, I can provide the GML and even a dump of the DB.
Hi,

Hi,
i´m using the 4.0.0 version of the the importer/exporter, when i export a little area of my database as KML/COLLADA/glTF the glTF files are missing. I only get the dae files. Have i to convert these files by my self (the examples if the web client are using gltf)?

Hello,
It's not my intention to publish an issue, but merely ask a question about the 3dcitydb project.
I am used to work with Maven repositories and pom.xml files.
It helps a lot when developing in, for example, Eclipse.
The whole dependency stuff is taken care of then.
My question is, why the 3dcitydb project doesn't use Maven ?
The two last days I attended a 3dcitydb workshop at the TU Delft, organised by Jantien Stoter and Thomas Kolbe.

Hello:
I'm not sure if this is the best place to ask questions, I apologise otherwise.
I want to use Cesium to visualise BIM files as 3D buildings and 3DCityDB looks like a great solution. However, I plan to use the standalone Cesium viewer once they release the 3D Tiles branch.
Do you know if it is possible to load the 3DCityDB glTF tiles as a Cesium3DTileset
into Cesium? In the other case, do you plan to implement 3D Tiles in the future?
Thanks and congratulations on the recent realease!

When exporting to KML/COLLADA/glTF, the root KML file containing the network links to the generated tiles uses DOS paths as <href>
reference:
<Link>
<href>Tiles\0\0\kml_Tile_0_0_collada.kml</href>
<viewRefreshMode>onRegion</viewRefreshMode>
<viewFormat/>
</Link>
The backslashes should be replaced with normal slashes: Tiles/0/0/kml_Tile_0_0_collada.kml

Hi,
I guess there is a little bug in the export function of the importer/exporter when it comes to exporting a triangulated relief feature with textures.
The issue seems to be that during export the gmlid of the triangles (linestrings) are added a "0", but this is not consistently done in the appearance.
Hence, when importing a dataset previously exported, you get an error message due due unresolved XLinks.
I have prepared a little example. In the zipped file (see later) you find the original input gml (tin_example.gml) and the corresponsing export (tin_example_export.gml).
You can import the first one, export it, but you cannot reimport the second one.
Is this a bug or am I doing something wrong?
Greetings,

Quick question, I have 3DCityDB exports working nicely now, and I've tested imports in EPSG:3857 and EPSG:4326. I'm doing large scale imports from OSM (eg, state-wide and larger) so I'm looking to use EPSG:4326 for accuracy. EPSG:3857 works for KML+GLTF exports but of course is distorted in Cesium.
I've done KML extracts in EPSG:4326 which look okay, but are very slow to render in-browser. Unfortunately exports in the GLTF format don't show up. Is there a fundamental reason why GLTF doesn't show up? I realize it may have to do with showing the vertices in degrees, but I didn't think this was a limitation of GLTF.
The KML/glTF export function works fine for footprint/extruded/glTF... although some glTF for my DB doesn't show up nicely in Google Earth Pro.
However, exporting as geometry only provides 2D data. The wall and roof surfaces seem to be represented without any variation in height. The altitude mode attribute is not defined in the geometry case, but setting this manually in file doesn't help.
heights for the extruded polygon of 1 building go from 0 to 13.6 using altitude mode "relative to Ground".
Heights for the geometry polygon of the same building go from 17 to 31 ... ie. they seem to be set not 'relative to Ground'. The geometry polygon produces different entities for Wall and Roof surface. But I don't see why this should matter?
(kml files attached, rename txt to kml).

Hi,
I use the 3DCityDB Importer Exporter tool to export my own CityGML data in the 3DCityDB database, but when the process finished, the FME Inspector show there is no geometry about the export file. I open the file with Notepad++(see figure 1), the right one should be figure 2. It looks like I miss some part during the process. I don't know which part is wrong, is the import part, the export part or the setup database part? Thanks for help
Kind regards,

For GLTF, it seems that you need to use the Cesium_RTC extension to support coordinates in WGS84? I wasn't able to get GLTFs in WGS84 coords to show up in the included web app, so I'm wondering if this may be the issue?

It's possible to use a geographic Projection (4326) for a Project and then to load different projected citygml files?
For example i have different epsgs for germany (25832, 25833,...) and want to load whole germany or europe or the whole world.
The COLLADA/glTF export function creates files with objects that align correctly with the Google Earth terrain altitude but not with the Cesium terrain. Is that correct and is there a method to align the objects to the Cesium terrain?

Hi. I'm using your library well. Thank you. I want to import the Citygml file from within Java.
I created the database according to the manual, and verified the connection through the program.
I also set the database information in the DBconnection class to import gml via Java.
I then used the code below.
However, the following error occurs.
What's wrong?

Dear all,
we would like to export our CityGML dataset to Collada but we are facing some issues during the export process.
In particular, from the 3D City DB log, the errors are raised up by a File Not Found Exception in the __temp folder (as you can see from the attachment image)
Which is the problem? With other dataset generated in the same way everything works fine.
Thank you for the support and best regards,

Hello,
I'm using the Cesium branch of the importer-exporter and I'm trying to export a textured building into one single glTF file (with embedded textures). Next to the created .dae and .jpeg files there is a glTF file, but it doesn't include the textures (just links to the texture files):
"images": {
"textureAtlas_1360110664_0_img": {
"name": "textureAtlas_1360110664_0_img",
"uri": "textureAtlas_1360110664_0.jpeg"
},
"textureAtlas_1360110664_1_img": {
"name": "textureAtlas_1360110664_1_img",
"uri": "textureAtlas_1360110664_1.jpeg"
}
},
When I'm running an export without glTF (creating solely the .dae and .jpeg files) and then perform a manual conversion using the collada2gltf tool (with option -e), it results in a glTF file that also includes the textures:
"images": {
"textureAtlas_1172405395_0_img": {
"name": "textureAtlas_1172405395_0_img",
"uri": "data:image/jpeg;base64,/9j/4AAQSkZJRgABAgAAAQABAAD/2wBDAAgGBgcGBQgHBwcJ...
},
"textureAtlas_1172405395_1_img": {
"name": "textureAtlas_1172405395_1_img",
"uri": "data:image/jpeg;base64,/9j/4AAQSkZJRgABAgAAAQABAAD/2wBDAAgGBgcGBQgHBwcJ...
}
},
I had a look a the KmlExporterManager and saw that the call to the collada2gltf tool happens before the images are saved to disk. So I changed the order (first saving the images, then calling collada2gltf), but the result is still the same. Any idea why the textures don't get embedded into the glTF file during the export but they do when I'm executing the collada2gltf tool inside my windows CLI?
Best regards,
Donato

Hi,
I tried to export my buildings using the KML/COLLADA exporter, but choosing CityObjectGroup as feature class in addition to other feature classes always results in 0 processed geometry objects.
The documentation about the feature class filter says:
The feature class filter in general behaves like for the CityGML import. However,
regarding city object groups the following rules apply:
- If only the feature type CityObjectGroup is checked, then all city object groups
and all their group members (independent of their feature type) are exported.- If further feature types are selected in addition to CityObjectGroup, then only
group members matching those feature types are exported. Of course, all features
that match the type selection but are not group members are also exported.
So I expected that checking every feature class would result in exporting my buildings. But to successfully export the buildings I have to uncheck the CityObjectGroup feature first.
Best regards,
Donato Marro
Hi? I have developed a CityGML ADE for Cadastre(UML and XSD). I am look for help to figure out the roadmap for importing and exporting the Cadastre-ADE examples data into 3d city db.
I have searched the web, but seemly there is no evident infomation about integrating CityGML ADEs into 3d city db?
My superficial roadmap is:
Can someone point out a reasonable way to accomplish my goal storing/exporting the ade data in postgresql?
Since we've moved the INDEX_TABLE
to the individual citydb schemas for PostgreSQL (cf. 3dcitydb/3dcitydb@5911550) , we may need to adjust the following code-line by adding a schema name parameter.
Hello,
I used the Tutorial „3DCityDB_V3.3_Hands-On_Tutorial“.
Exercise 4.1 export of one or several buildings are no problem.
I open the results within the software FZKviewer. All OK.
But.....
if I want to use the bounding box, I get errors:
After click on „apply“ (übernehmen):
[18:16:47 ERROR] Failed to transform bounding box to WGS 84: FEHLER: Input geometry has unknown (0) SRID
[18:17:03 ERROR] Failed to transform bounding box to WGS 84: FEHLER: aktuelle Transaktion wurde abgebrochen, Befehle werden bis zum Ende der Transaktion ignoriert
Another try I got the message
[16:56:05 INFO] Database export successfully finished.
but the gml file is only 3kb without buildings. FZKViewer have only 0 values for model boundingbox (SRS Dialog).
What should I change to get any result? Any ideas?
Thank you and greetings,
