MiniTransform Bug?

I ran into an issue when uploading my own minimesh, but it seems to be a quick fix (if the fix is correct) so I figured I would write it down here.

In the MiniTransform code:

chordatlas/src/org/twak/readTrace/MiniTransform.java

Line 120 in b77561b

double edgeLength = Math.pow( volume / ( count / targetCount ), 0.3333 );

Should this line actually be:

double edgeLength = Math.pow( volume / ( (double)count / targetCount ), 0.3333 );

which casts count to a double before dividing? Otherwise if count < targetCount, we are dividing by 0 and edgeLength becomes infinity.

Audio rendering - org.lwjgl.LWJGLException: Could not locate OpenAL library

I ran into random audio problems when trying to run the jar on some machine with questionable audio setup (I think a few people have messed with the installation of audio drivers). The error looks like the following (the error is thrown at startup):

I couldn't solve this problem because audio is not my area of expertise, but seeing that chordatlas doesn't use any form of audio, I was able to fix this problem by adding a line to disable audio rendering in jme3. Basically, after the initialization of jme3 AppSettings here:

chordatlas/src/org/twak/tweed/TweedFrame.java

Line 98 in 356af2b

AppSettings settings = new AppSettings( true );

I added a line to disable audio rendering:

settings.setAudioRenderer(null);

and the error stopped showing up. Yay. Clearly this problem doesn't show up very often but just in case this happens again.

Problem with Glasgow dataset and related error

I followed the user interface instructions and downloaded the glasgow_osm.zip dataset. However, on Step 3 downloading panoramas from Google, the following exception is thrown:

javax.imageio.IIOException: Can't get input stream from URL!
	at javax.imageio.ImageIO.read(ImageIO.java:1395)

If I go to the link thrown by the error (http://cbk0.google.com/cbk?output=tile&panoid=vV2SxgjEPMo0Vf3F5qEiEA&zoom=5&x=0&y=0) then I see a black screen.

If I go to another link used by the previous file in todo.list (http://cbk0.google.com/cbk?output=tile&panoid=mk9dFbTwGNpQiokh5to04w&zoom=5&x=0&y=0) then there is content.

My questions are:

1. Is this a problem with the data set or the code? My intuition is that this is the fault of the data set. If so, how do I go about fixing this?
2. This exception occurs on image 74 out of 523, and after the exception, the download of the panorama terminates (so we don't get any more images). Is there any way that we can continue to download the other panorama photos and just ignore this one scene? because it seems silly that the entire download thread would terminate just because of this one image failure.
   The interface also looks like it's missing some panorama points:

Unable to load meshes when trying to port to Gurobi 9.0.2

I built chordatlas on my machine to be able to use it with Gurobi 9.0.2. When I load the provided datasets (for example ny_osm), the GIS footprints appear but I am unable to load the meshes on top.

Steps to reproduce the behavior:

1. Clone and build the project but I change the gurobi version to 9.0.2 in the pom.xml file
2. File > Open > ny_osm > tweed.xml
3. Select the minimesh layer
4. Click on 'load all'
5. Here is the error log:

Thanks a lot for your work, it's really awesome! :)

integrated obj model export

Thanks for providing this awesome tool!

Is there any way to export the integrated minimesh models?

Is bigsur necessary to use bikegan? Can bikegan handle noisy mesh directly?

For example, I only want to generate texture for mesh, do I have to go through bigsur first, or is there an easy way for me to directly use frankengan to generate texture for the building, thanks!

Use java topology suite to recess all windows on a single wall

Problems with importing obj file and converting to skeleton format

Thanks for your wonderful work.

Now, I am using chordatlas to do some urban scene texturization projects and have some issues when following this pipeline. Firstly, I can not see the imported obj, should I change the world coordinate to make it visible? If so, how?

Secondly, after importing the obj (see the below figure, take the cube as the example), I can not see the "convert to skeleton" button. How can I run the ObjSkelGen to get the facade and window labels (like you showed in the video)?

Looking forward to your reply!!!

after importing tweedstreets, tools failed to load

hello, following your tips, I add tweedstreets project to Debug Configurtions -> ClassPath, but Tools failed to load.
if I set the classpath to the chordatlas ,the tools come back. ps: I run the project following your guide seriously, I have already set the resources both in chordatlas and tweedstreet as resource in the project structure. I donnot know how to fix it , please help me . your sincerely.

java.net.ConnectException: Connection refused

Hi,
I'm getting the above exception, when starting the JAR. Probably it's due to missing proxy settings, but
adding proxy options with
'java -jar -Xmx10g .\chordatlas-0.0.1-SNAPSHOT.jar -Dhttp.proxyHost=xx.xx.xx.xx -Dhttp.proxyPort=80'
does not change anything. So at the end there's no scene loaded.
Do you have any suggestions?

Thanks

FrankenGAN with chordatlas - bikeGAN root not found

I'm trying to run FrankenGAN (from docker) with chordatlas, but for some reason the textures are not loading like in the video.

I ran nvidia-docker run -v input:/home/user/bikegan/input -v output:/home/user/bikegan/output -it --rm twak/bikegan in a folder bikegan-temp, and I see the following output (I truncated lines from the top):

model [BiCycleGANModel] was created
Loading model bicycle_gan...
---------- Networks initialized -------------
[network super6 is awaiting input]
initialization method [xavier]
initialization method [xavier]
-----------------------------------------------
model [BiCycleGANModel] was created
all nets up
[network super10 is awaiting input]

If I check with nvidia-smi, I also see that /home/user/bikegan/test_interactive.py is actively running.

I leave the bikeGAN terminal untouched so the network can keep running. All other work is run on separate terminals.

At this point, if I check my bikegan-temp folder, I see that there is nothing there.

I followed the instructions and added the path to my bikegan-temp folder as my bikeGAN root in the settings menu. However, if I follow the steps in the aforementioned video or as the workflow here, I just see this output:

computing BuildingApp
batch 0/1 
finished 1 BuildingApps

timeout trying to get bikeGAN result 16059761037757--0.021439835879290325. 
is bikeGAN running? 
has bikeGAN root been set correctly in the settings menu? ([full path omitted]/bikegan-temp
time taken 10171

At this point, if I check my bikegan-temp folder, I see that it contains an input folder. The structure of the folder are as follows:

• facade labels
  • val
    • go, which contains "16059761037757--0.021439835879290325"
    • a bunch of stuff that looks like [email protected]_0.0_0.0_0.0_0.0_0.0_0.0_0.0_0.0.png
• facade labels_empty
  • val
    • a bunch of stuff that looks like [email protected]_0.0_0.0_0.0_0.0_0.0_0.0_0.0_0.0.png

There is also no output folder created in my bikeGAN root, which I thought was weird, especially since in the code where the error text is printed there seems to be some outDir that we expect to be created.

Is this the correct workflow I'm supposed to be following, or am I missing something?

Compiling Dataset - in tweed.xml, what is toOrigin and fromOrigin?

I'm currently trying to compile my own dataset, which is not too well documented, so this is sort of a clarification issue.

I'm trying to understand how tweed.xml came to be from the GML file. From the glasgow dataset, I deleted all the files other than the gis.gml file, and then I created a new "world" with File -> New and then choosing the GML file. I didn't see anything show up in chordatlas (black screen with no complaints), and if I hit Save, the tweed.xml file is fairly empty. In order to understand what I need, I started to slowly copy things over from the tweed.xml provided in the dataset.

It seems that a few things are needed in the tweed.xml file in order for the scene to properly show up:

• a <trans> tag, which I'm guessing is the transformation of the map with respect to lat and long. This value can sort of inferred from the boundedBy tag of the GML file. (I can just take the average value of the boundedBy tags and that seems to be close enough.)

• a <gmlCoordSystem> tag, specifying what version of the GML coordinate system we are using. This is also inferable from the GML file.

• a <genList>, where inside is a <org.twak.tweed.gen.GISGen> object that specifies where the GML file is. This is easily doable.

• finally, a set of two 4x4 matrices <fromOrigin> and <toOrigin>. This is where I'm getting confused - what exactly are these matrices? A quick check shows that they are inverses of each other, but I was wondering if there is a way that they are computed.

Own Data Information

Hi,

I am trying to generate my own data and as input I need panorama and minimesh. I can get the building footprint using QGIS and for panorama images I used Pano Fetch google chrome plugin( The Pano Scrapper Plugin is said to be not working in the link given)

1. How can I generate the mesh? Whether QGIS is used for this or the following link can be used?
   (https://github.com/tordanik/OSM2World/)
2. I have Panorama Images using Pano Fetch. How to generate Panos/todo.list which contain the panorama ID?
3. In the readTrace file,

what the following file/folder path should contain:
/home/twak/dump/blah
/home/twak/Desktop/frames.xml
/home/twak/Desktop/minimesh/

?

some questions of running with my own dataset

Hello, I have two questions to ask. The first one is that I want to test with my own dataset, but I don't know how to get the minimesh in the sample dataset, because I use aerial data for large-scale reconstruction and get mesh of multiple buildings. How to deal with the overall mesh to obtain minimesh?

Second, how does the imported footprint correspond to its mesh?

I am very interested in your work and have read your project code for many days. However, I am a beginner. I would appreciate it if you could explain your code organization structure for me!

Looking forward to your reply, thank you!

Error running super resolution FrankenGAN with ObjSkelGen

I'm testing FrankenGAN on skeletons generated from obj files (ObjSkelGen), and running the net with super (the super resolution networks) seems to throw an error. Running FrankenGAN on default (medium) seems to be working without problems.

When I run the net on super, it will generate all normal textures, and crash only at the part where the super resolution networks starts to work. Prior to crashing, it would have generated all textures on chordatlas (in other words, if I save the output obj file, I can still see the normal-level textures).

I have a dropbox link to the obj file. It should just be 3 prism-shaped buildings. One interesting thing I noticed is that when I imported the obj, the roofs (which are just flat surfaces) are blue. However, in the video for importing objs (https://youtu.be/aJek-uGjyc0), when you imported the cube, the top of the cube seems to be yellow. Does that make a difference?

The error is as follows:

CRS factories not in fat-jar

Usign the jar, I get the following message when loading a project with a CRS.

similar:
https://stackoverflow.com/questions/27429097/geotools-cannot-find-hsql-epsg-db-throws-error-nosuchauthoritycodeexception:

Solution
In the jar, in /META-INF/services/org.opengis.referencing.crs.CRSAuthorityFactory
add:
org.geotools.referencing.factory.epsg.ThreadedHsqlEpsgFactory
to the top of the list

org.opengis.referencing.NoSuchAuthorityCodeException: No code "EPSG:27700" from authority "EPSG" found for object of type "EngineeringCRS".

street information

hello，Thanks for your great work！
Apart from the paper itself, are you able to tell me about how were the roads in the rendering images generated?
Manually generated or fully automated？Looking forward to your reply.

problems about the gis data

Hello, I use the OSM data downloaded from OpenStreetMap and convert it into GML data with QGIS. However, when importing Chordatlas, the proportion of footprints has changed. I don't know why.
As a result, I couldn't align mesh and footprint because of the wrong scale.
It is normal to preview footprint in QGIS in picture 1.

and the result after importing into the chordatlas is as the second picture。
