In pkgcitygml.pc.cmake I see flags that requires libxml-2.0, but afaik libcitygml parses xml with xerces-c, is that a mistake?

I have citygml files with 'IntBuildingInstallation' tag what is not in source.
IntBuildingInstallation is not in the source. IntBuildingInstallation not handeled?

Hi,

thanks for putting all your good work into this. I really would like to give this lib a try but I am not c++ guy. So I tried for over a day now to get this to build (and the dependencies). So far I think I got a valid binary for xerces-c but when I try to compile libcitygml I get about 1000 warnings and 24 errors. Hunting those down lead me no where.

Long story shourt... I've seen that this apparently builds with CI. Could you send me a compiled .dll for windows? I'd be more than happy to send some beer money your way :)

Thanks for considering und viele Grüße

Thorsten

I've been working with a a couple of models from https://www.citygml.org/samplefiles/

• First v2.0 CityGML file (specifically the Part-1-Terrain-WaterBody-Vegetation-V2.gml file)
• Three LOD3 Buildings

Both of these models use ReliefFeature, but the CityObject for this returns 0 for both getGeometriesCount() and getImplicitGeometryCount(), and has 0 child city objects.

In FZK Viewer, the object tree for these files shows the relief:ReliefFeature as having a child relief:TINRelief object. This TINRelief object does not appear in the CityObject tree.

All the other features of the models seem to be working well. Am I missing something here?

I have citygml files with several buildings where no geometry is found, they consist of things like

      <bldg:WallSurface ........

First of all, thanks a lot for making this great library!

When importing some larger datasets I ran into some crashes.

This appears to be the cause:

• In the call to gluTessVertex we pass a pointer to elements stored inside the _vertices and _indices vectors.
• However, gluTessVertex does not appear to do any work until we call gluTessEndPolygon.
• At this point, _vertices and _indices may have been re-allocated (after successive calls to TesselatorBase::addContour which pushes new elements to them, causing them to re-allocate to fit a new capacity)
• The memory pointed to will be freed, and accessing it (in vertexDataCallback and combineCallback) will trigger undefined behaviour.

We can fix this by making sure the vectors containing the elements we send to GLU do not grow while GLU is processing them. That would be really simple if we knew before starting how many vertices we will need to add. Unfortunately I don't think we know that?

So here's my suggested solution:

• Build the list of vertices and indices for all contours, before starting to process them.
  • This will make sure calls to addContour will not happen while GLU is processing them.
• Copy the index value directly to the void* data parameter, so that we can safely add new elements to _indices (from Tesselator::combineCallback) while GLU is working with them.
• copy _vertices to a new temporary std::vector, and pass vertex pointers from this list instead, so we can safely add new elements to _vertices (from Tesselator::combineCallback) later.

It's confusing to explain, so I'll send you a PR 😁

but used by citygml_api.h

I'm using CityGML for years with my own I/O library, which is not complete and aging. But I have no time to ameliorate it today. I test your reader which is performing. But I need the writher too. Is it plan ?

As reported by Matthias Klose in Debian Bug #853487:

The package fails to build in a test rebuild on at least amd64 with
gcc-7/g++-7, but succeeds to build with gcc-6/g++-6. The
severity of this report may be raised before the buster release.
There is no need to fix this issue in time for the stretch release.

The full build log can be found at:
http://people.debian.org/~doko/logs/gcc7-20170126/libcitygml_2.0-3_unstable_gcc7.log
The last lines of the build log are at the end of this report.

To build with GCC 7, either set CC=gcc-7 CXX=g++-7 explicitly,
or install the gcc, g++, gfortran, ... packages from experimental.

apt-get -t experimental install g++

Common build failures are new warnings resulting in build failures with
-Werror turned on, or new/dropped symbols in Debian symbols files.
For other C/C++ related build failures see the porting guide at
http://gcc.gnu.org/gcc-7/porting_to.html

I have data that contains a cityobject like:

<gml:solidMember>
  <gml:Solid>
    <gml:exterior xlink:href='#otherobject'>
    </gml:exterior>
  </gml:Solid>
</gml:solidMember>

Looks like this causes it to run

While I understand why it's going into this condition, I'm not completely sure why it has to throw an unrecoverable error. Isn't there a different path it can take?

Or is it because xlink is not supported?

If I wanted to work on this, what is the workaround for this?

hallo dear, i have used cmake to build all files, now where should i provide my .gml files to get output ?thanks

Hello, thanks for the nice library. But I met some problems while reading my GML file.

For example, I have a GML file with such a member:

I successfully accessed the geometry child (frn:lod3Geometry), but failed to access those with external linkage (frn:class, frn:function). Are there any existing APIs for this purpose?

Thank you.

Hi,

Is there any way to get all material themes at geometry or polygon ? I did search to the latest code base but only found

    std::vector<std::string> AppearanceTarget::getAllTextureThemes(bool front) const
    {
        auto& map = front ? m_themeTexMapFront : m_themeTexMapBack;
        std::vector<std::string> themes;
        for (const auto& pair : map) {
            themes.push_back(pair.first);
        }
        return themes;
    }

There is function AppearanceTarget::getAllTextureThemes but no AppearanceTarget::getAllMaterialThemes.

Any ideas ? Thanks in advance.

Hi

The current master branch generates error when it parses a file with <gml:MultiGeometry> element.

Thanks in advance.

Hi :
I can get the vertex info from test gml file by using below sample codes, however there is no index or indics for these vertex info.
How can I get that ? My goal is to generate the mesh object by using vertex and index info.
Thanks.

std::shared_ptr myPolygon = inGeometry.getPolygon(i);
std::shared_ptr myExternalLinearRing = tempPolygon->exteriorRing();
std::vector myExternalLinearVertices = myExternalLinearRing->getVertices();

As

<bldg:lod4Geometry>
  <gml:MultiGeometry>
    <gml:geometryMember>
        <gml:MultiGeometry>
            <gml:geometryMember/>
        </gml:MultiGeometry>
    </gml:geometryMember>
  </gml:MultiGeometry>
</bldg:lod4Geometry>

Models containing "spaces" (from CityGML 3.0) will fail to import. Examples being gen:GenericOccupiedSpace.

See OGC docs: https://docs.ogc.org/guides/20-066.html#ug-coremodel-section

Here's a sample model (converted form CityJSON):
cube.city.zip

I'll start working on support for this and send you a PR, if you don't mind :)
From what I can see it should be pretty simple to do. Just a matter of adding some new node types, and extend the if-checks in cityobjectelementparser.cpp.
Update: Ok, so probably a bit more than that, when including the new additions to "transport", that depend on this..

When parsing a node we always create a new CityObjectElementParser.

This causes an exception to be thrown in CityGMLElementParser::endElement (see citygmlelementparser.cpp) if the only contains children that are ignored (because they haven't been implemented, etc.).

I've created a test file (modified version FZK-Haus) that shows the problem:
ignore-test.zip

This is the model where I first encountered this problem (because it uses "grp:CityObjectGroup", which is not implemented):
LoD3_Railway.city.zip
I've encountered the same issue on other models too.

I suggest replacing that error with a warning, and instead handling this case. I can create a PR for that. Though, please correct me if you think that would be a bad idea 😅

In the case of a container element containing a child element with an xlink, it should also be safe to continue parsing - but it's fair to print a warning, since that element won't be parsed. I noticed once case where that happens (tran:intersection with an xlink - which isn't handled at the moment). I might make a bug/PR for that too.

And by the way, thanks a lot for making this amazing library!

As the heading suggests, I don't seen any references to the ParserParams::minLOD and ParserParams::maxLOD member variables. These seem to be dummy variables for now.
Is there any plan to support these options?

Hi,

I've had a look through the repository but I can't find any details about the following:

Which version of CityGML is supported?

What features are not currently supported for the supported versions of CityGML?

Thanks

Since code.google.com is shutting down, and the libcitygml project there has been dead for awhile, are you planning to tag releases here on GitHub?

This looks like the most viable successor of the Google hosted project and I'd like to switch the libcitygml Debian package to use this repo. Having tagged releases makes it much easier to package.

I wanted to know about critical OpenGL is to libcitygml? I see that it is only used in tesselator.
Would it be possible to disable this via a CMake option? How would this impact the rest of the loading pipeline?

Note: I am not using OSG.

Recently, I have tried to create the binary project from the cmake source using CMake 3.4.1 gui form but receive the following message,

CMake Error at CMakeModules/FindXerces.cmake:109 (MESSAGE):
Could not find Xerces-C !
Call Stack (most recent call first):
CMakeLists.txt:134 (FIND_PACKAGE)

Do you have the procedure or document to explain how to convert the cmake source code into the binary project so visual studio can access?

where do I switch off logging in citygml::load?
passing nullptr as logger in the 3rd argument does nothing

I did have to make some trivial changes to compile with vs2012. I can provide this code if you are interested. CityGML_2.0_Test_Dataset_2012-04-23 is what I'm using, and no matter test data I choose it parses for a while and hits this condition. I was only doing a spot check of this library and it doesn't look like its working out of the box. Can you test with the citygml test data and see if you are also getting this exception thrown?

if (!m_boundElement.valid()) {
// This might happen if an container element that usally contains a child element links to an exting object using XLink an thus
// uses a combined start/end element: e.g.:
// For such elements a child parser must only be created if there is no xlink attribute.
CITYGML_LOG_ERROR(m_logger, "CityGMLElementParser::endElement called on unbound " << elementParserName() << " object for element <" << node << "> at " << getDocumentLocation());
throw std::runtime_error("CityGMLElementParser::endElement called on unbound CityGMLElementParser object.");
}

hallo it shows this error when i run
it shows this error

I want to write out osg node to citygml

Hi,
I'd be willing to add LOD0 parsing to libcitygml.
However, I'm not sure if this project is still active and if a pull request could be considered ?

Thanks

when i using camke to configure libcitygml

how can i fix it?
i use libcitygml0.1.3 & citygml2vrml v.0.1.3 & XERCES 3.1.1
Visual Studio 2010
Windows 7 x64

When I load a model and use the WGS84 as the destination SRS in params, the model is transformed correctly, but the envelop for the model is not transformed. cityModel->getEnvelope().srsName() returns the original SRS and the values remain same as when there is no destination SRS.

As far as I checked, there is no one-off function to transform coordinate systems, this can only happen at model load.
