Please support "WebCamTexture" in unity. This allows more platforms to be supported. I've been looking into using ARtoolkitx to bring AR effects to more platforms. However, some platforms support a native API to capture the camera footage. While it's great to support Windows, Android, iOS in the ARtoolkitx source code, there are some platforms that don't support it. Use unity's 'WebCamTexture' to support many more platforms from the unity native code level.
Please add this feature. Thanks!

While it's ALWAYS crashed the iOS version, I've found that Native GL Texturing is causing crashes in the Android build now.

I've noticed that performance seems quite a bit better without the option anyway, so Native Texturing seems a little less necessary right now. Still, since it's an available option, I thought it'd be best to check.

When I try to build arunityX in my Windows 7 with Git Bash for android I get the following error message:

FAILURE: Build failed with an exception.

• What went wrong:
  A problem occurred configuring project ':arunityXPlayer'.

SDK location not found. Define location with sdk.dir in the local.properties file or with an ANDROID_HOME environment variable.

How can I fix that?

1. I checked-out : https://github.com/artoolkitx/arunityx

2. I checked-out : https://github.com/artoolkitx/artoolkitx and put them to D:\Projects\ARToolkit\arunityx\Source\Extras\artoolkitx

3. I went to : D:\Projects\ARToolkit\arunityx\Source and opened GIT BASH, and executed command
   .\build.sh windows --dev

4. I got error
   "+ cp -rf /d/Projects/ARToolkit/arunityx/Source/Extras/artoolkitx/SDK/bin/ARX.dll /d/Projects/ARToolkit/arunityx/Source/../Source/Package/Assets/Plugins/x86_64/
   cp: cannot create regular file '/d/Projects/ARToolkit/arunityx/Source/../Source/Package/Assets/Plugins/x86_64/': Not a directory"

So I manually copied ARX.dll from D:\Projects\ARToolkit\arunityx\Source\Extras\artoolkitx\SDK\bin\ to D:\Projects\ARToolkit\arunityx\Source\Package\Assets\Plugins\x86_64

5. I opened an example scene, BarcodeScene.unity

6. Upon loading, I received three of this error on my Console :
   DllNotFoundException: ARX
   PluginFunctionsARX.arwRegisterLogCallback (.PluginFunctionsLogCallback lcb) (at Assets/artoolkitX-Unity/Scripts/PluginFunctionsARX.cs:89)

I see that the ARX.dll is already in Assets/Plugins/x86_64 in my unity Project tab.

BTW, sometimes I also got error :
FileNotFoundException: D:/Projects/ARToolkit/arunityX Samples/barcode/arxExampl_Data/Plugins/ARvideo.dll does not exist

I see that the ARVideo.dll was not built, but ARVideo.lib was built.

Thanks.

@ThorstenBux - Trying to upgrade an existing v5 project to X, and I've run into this issue.

Currently building for Windows.

I initially simply copied the files from the source version over my existing version (after ensuring I grabbed the Windows and Android binaries).

When that had the DLLNotFound exception, I then downloaded the latest release UnityPackage and installed it into my project. I did NOT include the items trying to install to C:\ drive, or the stuff from the Packaging system.

Still didn't work.

When I use Dependency Walker, it's indicating that it's looking for the OpenCV DLL files and not finding them (this can often trigger a "The Specified Module Could Not Be Found" error in Windows.) Did the Windows DLL somehow get compiled with dynamic linking against OpenCV instead of static linking?

With an app with the correct permissions configured, the following error occurs on Android when starting the app

Hello, I'm trying to add animations to the AR content whenever the tracker is lost. I managed to make the events OnMarkerFound and OnMarkerLost work. I even managed to make the animation work for OnMarkerFound, but it seems OnMarkerLost freezes the content.

Is there any way to make an animation of the AR content trigger when the marker is lost? I have tried with both ARToolKit5 and ARToolKitX.

After I finally managed to compile the ARX.dll for Windows using mingw/cmake/Visual Studio 2019 and imported it alongside other libraries into Unity (see image) I always ended up crashing the editor as soon as I hit play.

After some digging in the code and in the Unity logs I found the problem in the file videoRGBA.c:

int videoRGBA::videoRGBA(uint32_t *destRGBA, AR2VideoBufferT *source, int width, int height, AR_PIXEL_FORMAT pixelFormat)

In case AR_PIXEL_FORMAT_420f bufPlanes has no valid index 0 and the access causes the access violation:

I also found out that in video2.c it uses ARVIDEO_INPUT_WINDOWS_MEDIA_FOUNDATION if that helps.

I have been trying to fix it myself but I am not very familiar with the code and haven't managed to get a working build with correct image output. All I managed to get was a green screen. So any help is appreciated!

Hello, everytime I use StopAR or StartAR, ARTooKit resets itself. Anyone knows how can I stop or start it whenever I want? Thanks

When running on Android, the Load() function kicks off a call to unpackStreamingAssetToCacheDir()

This appears to work correctly when the markers are pre-configured (ie. you create the ARTrackable in the scene and build it in).

However, if your markers are created at runtime, you get an UnauthorizedAccessException each time Load is called for a runtime marker when attempting to access the cache directory in Unity 2018.4 (the long-term-support version).

You get the following log message in logcat: Access to the path '/storage/emulated/0/Android/data/application id/cache' is denied.

Is ARToolkitX somehow locking the cache folder? I've noticed that the cache folder is passed to ARToolkitX as a parameter to the video in Android versions. Perhaps we instead need to create a subfolder for the video cache?

Hello,

I'm targeting Android.
I try to set my frame resolution through the Unity inspector but I get a message saying that my width and height parameters will be ignored and instead artoolkitx opens the frame using a lower resolution.

While pre-processing image trackers is useful, it would also be beneficial to create image tracker references at runtime dynamically.

This would allow the following use cases:

• Downloading a tracked image and registering with the image tracker
• Capturing of new tracked images using the camera for identifying the placement of new content

Modern Unity Editor serialization model requires marking of dirty fields etc. Need to update ARControllerEditor (plus probably other custom editors).

Hello everyone,

I try to use ARToolkitX on Unity with ARUnityX.
I have Unity 2017.4.15f1 on Windows 10.

I downloaded the last version of ARUnityX (this git) and folowed the instructions to build it for windows and android.
I ended copying some files from the Source folder to my Unity project. Here are the files I copied :

• Folder "artoolkitX-Unity"
• Folder "StreamingAssets"
• In Plugins :

When I open SimpleScene and run it in Windows, it works fine.
When I run it on ANdroid, the screen stays black, and in Android monitor, I can see :

"Ok - True .... Got Frame - False"
It looks like writing it each frame, it makes me think the program tries to access camera but fails.

Here is my manifest (I changed the package name to "com.artoolkitx.testUnity" in Unity) :

Any ideas ?

Thank you

The modern way of deploying packages in Unity is via UPM (Unity Package Manager).

Consider updating the Unity package repository to match the UPM project layout, rather than making a .UnityPackage export, which is safer and provides versioning (plus allows publishing to OpenUPM)

https://docs.unity3d.com/Manual/cus-layout.html

A good example is the RealityCollective packages which have automation to manage building/testing and tagging for OpenUPM
https://github.com/realitycollective/com.realitycollective.service-framework

When built for Android, running any of the example scenes on an Android device only results in the following errors:

Intro
I used to work with arunity5 (https://github.com/hsnk/arunity5) which I think is more efficient.I mean the camera resolution and detection is great and more accurate. However, it doesn't support arm64 processor on android.

So, I had to move to arunityx because it is the only artoolkit unity that supports arm64 android build.

Issue
In "moto z play" phone, the app can not recognise the "hiro" marker (building the sample scene). or to be more accurate I had to go back with the phone cam and when a recognisition is stablished, the cube appear like floating way above the marker. like in the front of the cam.

on the other hand, the app on "Oppo A3" phone works fine (i.e. the cube is there above the marker). Does anyone have this issue??

Also,may be this is not the right place to ask, but is there any chance for arunity 5.3 to support arm64?

Again many thanks

Use of string "tag"s to link objects is error-prone and low-performance. Replace with event model.

Tried in 2018.4 and 2019.1

Tried using the files provided in the official release UnityPackage, and files taken from the latest commit.

Used the ARX dll that came with the package, and the ARX DLL that is in the latest version of ARToolkitX. Used the OpenGL DLLs found in the ARX package.

Brand-new, clean project.

HOWEVER - please note that I'm also having trouble getting the samples included with the Windows ARToolkitX demo working. They all report the following...

[error] Error: a required OpenGL function counld not be bound.
[error] Error initializing display of video frames from source.
[error] Unable to init ARVideoView.
[error] Error in ARController::drawVideoSettings()

This might be something completely different, since it appears to be in the PRESENTATION of the information. However, I've reported this on the artoolkitx issues list.

I attempted to follow the first 6 steps outlined in the quick start read me. ran both ./build.sh and attempted to run ./package.sh (in their respective locations) but when I run ./package.sh I get the following error:
sed: can't read s/artoolkitX for Unity Version (([0-9]+.[0-9]+)(.[0-9]+)?(r[0-9]+)?)/artoolkitX for Unity Version 1.0.5/: No such file or directory

I have tried making it 1.0.6 in which build failed and 1.0.2 (which is the default) which gives the same outcome as 1.0.5, any guidance would be appreciated. screenshot below is my console in git-bash. I am attempting to use it for unity on windows.

Is this related to artoolkitx/artoolkitx#40 ? Due to cparamSearch.c it should try to curl from https://calibration.artoolkitx.org/app/calib_camera/download.php which does not seem to be offline. But when I sniff the apps traffic through Charles proxy, it doesn't try to connect to artoolkitx.org at all.

Is there any documentation, that could point me into the right direction?

I use artoolkitx to rebuild the SDK and examples for iOS, and use arunityx to rebuild unitybackage.(arunityX-1.0.6.unitypackage)
Use untiy to create a new project, import unitybackage(arunityX-1.0.6.unitypackage), export ios project, and then use xcode to open the ios project. Build the project.
Then there was a problem.

The current .UnityPackage for the project is polluting the Unity project with external package dependencies that are not part of the ARUnityX package.

I recommend excluding these from the export until #41 can be done.

Is it possible to build the package without ARToolKitx libraries? Because I am not able to understand

1. I don't have ARTOOLKITX_HOME set.
2. what to pass as a version number in arunityX-bin.sh

Error:
You need to run ./build.sh before packaging.
sed: /SDK/Frameworks/ARX.framework/Headers/AR/config.h: No such file or directory

I tried to run BarcodeScene example. At first, it said that ARX.dll was missing, but I used one of the solution provided by users in the issues. Now I'm having the issue on building gradle step. This is full error message:

I have linked my external tools, such as SDK and NDK to Unity preferences.

please update

Currently I'm looking for vuforia alternaitves and ARToolKit seems promising. As far I understand, ARToolKitX replaces it and seem to be in active development. And because I'm a Unity developer, this seem to be the right place.

So I checked the releases tab and the only release I found was the default.unitypackage.unity... downloaded, imported to Unity 2018.2.18 and voila:

I never saw these errors nor a plugin, which tries to write to my C: drive.
This doesn't seem right. Very strange paths. Is anyone working with artoolkitx and unity?

So it appears that the utilities (like genTexData and calib_optical) don't exist in the arunityx files. No worries, I downloaded both the artoolkit5 and artoolkitx. The artoolkit5 files seem to have all of them and the artoolkitx has most of them BUT they are in .c format with makefiles. I tried running the .c files as I would an .exe file in console but I got the error shown below:

Did this happen since the makefile wasn't used to create an .exe? If so, how would you recommend doing that on Windows? I have the windows-linux subsystem set up and considered using that but would like to ask first. Thank you

Hi Guys,
Can someone please build the latest package of ARToolKitx and either upload it on arunityx repo or made it available at http://www.artoolkitx.org/docs/downloads/

I am facing an issue in building the package locally. Refer #2

Hello,
I've been using arunityx to assist me in a AR project that I'm working on, but I'm facing an issue.
While testing the app in Unity everything is fine, but when I build it to android and test it in Android Studio, the video gets extremely low res, as show in the log. (I'll attach pictures showing what I mean, bellow)
After building the apk and testing it, the video is still low res. (just like Android Studio)
Any idea how to fix this?

Emulated device: Nexus 5X
Tested devices:
Xiaomi Mi A1
Vodafone Ultra 6

For some reason, the Gradle distribution chosen to rebuild the Android extras doesn't work in Windows - at least on my machine.

By updating the distribution to 4.6 instead of 4.1, it compiles successfully.

When running on Windows the Unity Player (also happens on standalone) crash as soon as we update the texture. I can't get anymore info on the crash because the Unity player just dies on the spot.
This problem does not happen on MacOS.
The pixel format detected is Video 640x360@1Bpp (AR_PIXEL_FORMAT_420f)
If i supply #-format=BGRA# into the ARController Video Config. (Windows) it gets the camera texture fine but not tracking occurs.
Anyone else experiencing this?

Thanks

Hello,

The package.sh script is for Mac only,

The last but one line, where Unity is called to create the package does not work on Windows.

I changed it for myself to

/cygdrive/c/Program\ Files/Unity-2018-1-6f1/Editor/Unity -quit -batchmode -nographics -stackTraceLogType Full -executeMethod ARToolKitPackager.CreatePackage -projectPath /home/peter/peter/Source/Repos/arunityx-master/Source/Package ARUnityX-1.0.2.unitypackage

This does not produce an error, but also does not create the ARUnityX-1.0.2.unitypackage.

Can anybody tell me what I am missing?

While I was previously able to build, I couldn't run on device as Apple has updated their Xcode platform.

Now I cannot even build as I get the following error in Unity:

EntryPointNotFoundException: arwRegisterLogCallback assembly: type: member:(null)
PluginFunctionsARX.arwRegisterLogCallback (PluginFunctionsLogCallback lcb) (at Assets/artoolkitX-Unity/Scripts/PluginFunctionsARX.cs:99)

I'm at a loss :S

I am trying to extract package from the git file i downloaded but i am getting this weird error and really not sure what is it? Please if someone can help me to solve this error and help me extract unity package from git source of AR Unity X. Image for error https://drive.google.com/open?id=18Bt-wCRX9gVqiP9rhVn2TYrqfPuXbM5C

Request from @SimonDarksideJ: allow entire workflow for marker creation to be run without leaving Unity Editor.

• For 2D planar tracker, allow tracking point visualisation.
• For square template markers, allow specification of marker image.
• For square barcode markers, display in-Editor.

In AR applications, the camera frustum is the same aspect ratio as the video background texture, but this may differ from the aspect ratio of the display. In video background "fill" mode, the video background texture completely fills the display, such that some of the video background may be outside the display bounds (i.e. cropped left/right or top/bittom).

Normally, this is done by scaling the viewport. See e.g. https://github.com/artoolkitx/artoolkitx/blob/master/Source/ARX/ARVideoView.cpp#L118. However, Unity doesn't accept negative values for a Camera's viewport left or bottom values, therefore an alternate approach is needed.

One such approach would be to crop the video background (set vertices to the same shape as the display, and adjust texture coordinates to match) but this also necessitates adjusting the generated artoolkit camera frustum; a little more complex! See https://github.com/artoolkitx/artoolkitx/blob/master/Source/ARX/AR/paramChangeSize.c

I suppose this is an old issue, see this post.

I got Unable to start AR tracking. Please check that you have a camera connected. error when I press Home button then go back to the app

libAR: [error] ARController::androidVideoPushInit: ARVideoSource is either closed or already running.
E/CameraEventListenerUnityImpl: arwAndroidVideoPushInit failed

and the camera freeze.

How can I get the camera back to work when I get back to the application?

If the issue is already solved in this repo, could someone please point me to the part of code that is responsible for this? I am using some mixed Unity .cs from ARUnity6 and ARUnityX and I can't afford the time to replace the whole project with ARUnityX files now. Thanks.

What does this mean？

The device is running on Nougat (7.0.0)
Camera is set to 640x480, thus the buffer size should be 406800, I don't understand where 368512 comes from.
Here is what the planes from reader.acquireLatestImage() look like

I was trying to build unity example name 2DScene with virsion Artoolkitx.1.1.4 but I am not getting proper Image of preview image is coming as random rgb image. My unity version 21.3.13f1

such random image is comming.

Hello, I know the is a similar issue but mine is different. I downloaded the released package of arunityx, imported it open a example scene and when I try to build the program that error pops up.

I will copy the full error.

DllNotFoundException: ARX

I don't know where that dll should be, so i can't see if it's there. Am i missig something? did I do something wrong?

I'm building it for android.

By the way I did the same thing with arunity5 and it works fine-ish, it have that long time black screen problem because of the camera calibration so I would really like to be able to use arunityx. Thanks for the help.

Hi ARToolkit Community,
First of all thank you for keeping running the ARToolkit project!

I followed the Getting Started Guide and was able to run on MacOS Editor, on iOS and Android phones with few changes ( I can share if somebody finds it useful ), but noticed that arm64-v8a for Android is missing from the generated unity package. Any reason it is missing? I see the library in the ARToolkitX SDK for Android so maybe I am missing something.

Thank you

i use windows 7
i already run build.sh and get this result:

and then i try to packaging i get this error:

can you help me? i already follow the instruction in https://github.com/artoolkitx/arunityx/blob/master/Quick%20start.md
