The occlusion does not work for me, I can still see the virtual object (armarker) behind real world objects.

I was browsing through several forums.
but to get the deltaCam matchin with the Camera image is really tricky. Tried to do some Matrix transformations. But i am not entirely there:

` // line 341 in: private void _UpdateTransformationFromPose(TangoPoseData pose) :

  m_colorCamOffs = Matrix4x4.TRS(m_camOffsetXf,m_camOffsetRot, Vector3.one);

		Matrix4x4 cTuc = new Matrix4x4();
		cTuc.SetColumn(0, new Vector4(1.0f, 0.0f, 0.0f, 0.0f));
		cTuc.SetColumn(1, new Vector4(0.0f, -1.0f, 0.0f, 0.0f));
		cTuc.SetColumn(2, new Vector4(0.0f, 0.0f, 1.0f, 0.0f));
		cTuc.SetColumn(3, new Vector4(0.0f, 0.0f, 0.0f, 1.0f));

        m_uwTuc = Matrix4x4.TRS(position, rotation, Vector3.one);
		Matrix4x4 uwOffsetTuc =  m_uwOffsetTuw * m_uwTuc * m_colorCamOffs * m_colorCamOffs * cTuc;	`

rotation works somehow but translation parameters from this discussion
get somehow squared: http://stackoverflow.com/questions/36476910/camera-offset-project-tango

Because #87 is closed, I am opening a new ticket here because the example built on Unity 5.2 is crashing on my Tango.

The error I got is "Channel is unrecoverably broken and will be disposed!" and I did not see any code exception.

My Tango's model is NX-74751 Development kit.

Android Version is 4.4.2

I try to run the sample project via Android then I got this error message

What I'm missing here? I didn't touch any codes inside it.

i Don't know when it happened exactly but either after:

• I upgraded Tango Developer Kit to current Updates via System Settings or...
• I Upgraded from Unity 5.3.5p7 to Unity 5.5.0p4
  Deploying with Debug Symbols the tablet prompts the following message on the Android Monitor's logcat in Android Studio:

01-25 21:31:13.001 537-558/com.xxxxxxxxx.unityexamples I/TangoEGL: checkAndUpdateEglState: invalid current EGLDisplay

or

01-25 21:32:09.688 537-558/com.xxxxxxxx.unityexamples I/TangoEGL: checkAndUpdateEglState: invalid current EGLDisplay 01-25 21:32:09.695 537-571/com.xxxxxxxx.unityexamples E/Unity: OPENGL NATIVE PLUG-IN ERROR: GL_INVALID_ENUM: enum argument out of range (Filename: ./Runtime/GfxDevice/opengles/GfxDeviceGLES.cpp Line: 299)

it's hard to track down where the error comes from exactly because the origin to this library is hard to track: ist it coming from the TangoManager or the EnvironmentLight texture. the message is Promted in SurfaceTexture.cpp and some environmentalLight - library
maybe there is also a Camera Permission Issue. But so far older Versions built with Unity 5.3.5 work just fine under this aspect without asking for a camera permission.
GL_INVALID_ENUM might be a reason of an incompatible VideoOverlay setting in the TangoManager

On the new version of unity 5.4.0, using the google unity activity causes a crash with the error of "Unity Android Application “Unable to load native library”"

I was build & run a simple scene to my Samsung GT-N7100 but the camera doesn't rotate when tilting the device. Any help ?

Hey,

I am attempting to utilise the GVR spatialiser plugin in my tango project which is an ever so slightly adapted version of the mesh builder with occlusion example. I eventually managed to work my way through to a successful compile, through using a blank project, importing GVR SDK, then Tango SDK and a few horrible edits of the android manifests.

The audio is currently playing and appears to be spatialised, when I select a new world position for the AR marker the HRTF appears to change and does indeed sound like it is coming from the direction. However all "head" (phone) rotation and movement does not work, the HRTF filters appear unchanged.

I currently have only GVRAudio related objects within my scene, is it possible that the GVR Audio Listener needs a GVR associated object in order to determine its positon/rotation (like a GVR head?) I haven't used GVR before this project and really only want the spatialiser, I am currently having to use oculus and would really like the extra features from GVR.

And is there an accepted standard way to integrate GVR and Tango?

Thanks

Hi @chaosemer ,
I'm getting this error "Failed to Connect to Tango Services" after updating to Hopak release in Unity.
I wonder if Hopak release is stable?
Same app used to work fantastic in previous releases.
I'm using Tango Development Kit.

Any help....please.

I'm getting hit with an error when building these unity examples:

DirectoryNotFoundException: Could not find a part of the path "C:\Users\Christopher\Desktop\tango-examples-unity-master\ExperimentalProjects\MeshBuilder\Assets\Plugins\Android\tango-ux-support-library\bin\classes\com\google\atap\tango\ux\components\ExceptionStatusComponent$ExceptionStatusComponentListener.class" or "Temp\StagingArea\android-libraries\tango-ux-support-library\bin\classes\com\google\atap\tango\ux\components\ExceptionStatusComponent$ExceptionStatusComponentListener.class"

I followed the path and it does exist.

I've had very mixed results, ranging from being able to build the point cloud, area learning, and motion tracking examples, but not the experimental examples, to being able to build the examples but the axes are rotated improperly. It's a mess.

I'm suddenly getting this error while running any Tango enabled app (Google's Tango Explorer app etc..or my own build):
Error: Incorrect Configuration. Please go to Settings-->Developer options and use ART

By default the device came with dalvik & was running fine.
I've read some posts pointing the issues with using ART.

Still I switched to 'ART' and after rebooting the tablet, all the apps that were installed before changing to ART works fine(tango capabilities) but if I install a new tango-enabled app its not able to access tango core and throws an error.

What should I do?

Hi,
The tracking work very well, I try to save my area into the system , and it is always failed.

adb on terminal shows this error :
I/Unity (14202): Could not save area description.
I/Unity (14202): at System.Environment.get_StackTrace()
I/Unity (14202): at Tango.AreaDescription.SaveCurrent()
I/Unity (14202): at SaveADFController.KeyBoardBehaviour()
I/Unity (14202): at SaveADFController.OnGUI()

I use unity 5 under Mac .

is there any solution please

Thanks

The area learning sample has an empty scene. Is that intentional? The sample as-is builds but is stuck at "powered by unity" screen as there is no camera or anything else to initialize in the level.

Hi,

I have an exception being throw when using video overlay in TangoSetupTeardownManager because its member m_yuvTexture is null. This cause seems to be that the initialization order is wrong. As we can see here the texture is created after having created the TangoSetupTeardownManager. I think an easy fix is to set up the creation of the texture sooner in the code.

How can I know the ADF's origin(0,0,0). I want to allign Unity's World origin with tango ADF's origin.
The metadata doesnot contain anything.

I find a problem, under this TangoSDK/Examples/Scenes/ folder, the SimpleAugmentedReality scene can work, but can't see the reality world, just see the virtual world.

I try to create a simple project for depth perception, unfortunately PointCloud not found inside component.

Please advice. Thank you.

it's a bit odd because on some builds it works without error and in others the error appears again. The most stable Configuration with the Developer Kit is: Building with mono2x and Gradle. With the internal or IL2CPP it's so far permanent. I am building with Unity 5.5.0p4

Screen capture applications doesnot run in Project Tango dev kit tablet.
They asks for root permmissions. I'm wondering if this is b'coz of Android SDK version it is running.
If so then how are Tango devs sharing screen in their demos.

I develop tango AR app using Unity, I want to record the AR video, but I can't find a API to record video in the tango Android device, so I have to use Android API. in the Unity project, I import tango's unity SDK package, so, at Plugins/Android directory, there are a AndroidManifest.xml file and google_unity_wrapper.aar, If I want to use Android API, how to integrate my code into google_unity_wrapper.aar? or, how to use AndoridIntergration directory?

Just wondering what happened to the latest PersistentState demo: As soon as an area has been localized I frequently get false coordinates which causes my viewport to jump (sometime it's several frames in a second). Has someone come across the same behviour?

because of the low version tango core, so in the example, it shows out of date. I have no way to download new version tango core, what can I do?

As per subject, i got this error when try to build and run the project. Even already import UnityEngine, the error message still occur.

http://docs.unity3d.com/ScriptReference/AndroidJavaProxy.html

Assets/TangoSDK/Core/Scripts/Common/AndroidLifecycle.cs(26,42): error CS0246: The type or namespace name `AndroidJavaProxy' could not be found. Are you missing a using directive or an assembly reference?

Please advice. Thank you.

When I select an existing ADF and click extend, the produces the following error message:

Failed to connect to Tango Service.

Same issue can be reproduced when I set area description learning mode to be true, and start the tango application with an existing ADF in AreaLearning example.

I got this error message when trying to build and run on my android device using Unity5. Is it related to google API issue? All libraries required by this project.

Hi, I was experiencing issues running apps on my Tango so I uninstalled and re-updated Tango core, which worked, but then found that it had deleted all of my ADF files. To test , I created another ADF and re-installed core again and the same thing happened.

'TangoPoseData.pose.status_code' is VALID after localization. But when I step out of the AreaDescription the status_code doesnot change, its still VALID. Ideally it should be INVALID.
I'm using AreaDescription & StartOfService as coordinate frames.

Hey,

This may be possibly related to issue #80 but within my application, if I scan an area and end up with too large of a mesh (can not say the size for certain) the mesh fails to save within the area description. The XML for uuid is generated but with blank vertecies/triangles fields. Is there a built in mesh size limit?

My application is an extension of the mesh occlusion example, the only tango related attributes I have changed is the 3D Reconstruction resolution to 0.05m meters

https://github.com/googlesamples/tango-examples-unity/blob/master/ExperimentalProjects/MeshBuilder/Assets/Scripts/Voxel.cs#L129

https://github.com/googlesamples/tango-examples-unity/blob/master/ExperimentalProjects/MeshBuilder/Assets/Scripts/Voxel.cs#L42

the variable 'voxel' on line 129 hides the variable voxel on line 42. Consider renaming the variable field on line 42 to _voxel or myVoxel or something.

i'm trying to use this repository to look at some examples of tango uses, but i can't find the scenes associated with the scripts and prefabs.
where are the scenes for UnityExamples/Assets/TangoSDK/Examples/*?

thanks!

I try to implement motion tracking but I have a bug.
When the tablet is too close to a wall, the app crash.

As per subject, is it possible? Or it has face recognition in real time?

Hey has anyone had luck getting the mesh builder example to run or had luck integrating it with another unity project?

When I open the meshbuilder.unity scene its just a handful of scripts not connected to any game object, and when the project is compiled and launched on Tango it just crashes instantly

In an effort to better understand mesh generation I have been going over the meshbuilder code. I think I may have found a minor bug. I have not replicated this in unity, but, I do have a console application where I am replicating / testing the logical internals.

https://github.com/googlesamples/tango-examples-unity/blob/master/ExperimentalProjects/MeshBuilder/Assets/Scripts/Voxel.cs#L113

            } else if(parent.leftTree == this) {
                //point parent directly at child
                parent.leftTree = (leftTree != null) ? leftTree : rightTree;
            } else if(parent.rightTree == this) {
                //point parent directly at child. **Bug Here**
                parent.rightTree = (leftTree != null) ? leftTree : rightTree;
            }
            return true;
        }

If the node has a right child the child may get pruned unexpectedly. Here is a fixed version.

                else if (ReferenceEquals(parent.Left, this))
                {
                    // Delete Leaf Node
                    parent.Left = Left ?? Right;
                }
                else if (ReferenceEquals(parent.Right, this))
                {
                    // Delete Leaf Node
                    parent.Right = Right ?? Left;
                }

To demo this error take the following tree :

C10
- L5
- - L4
- - - L3
- - R8
- - - L6
- - - R9
- R15
- - L14
- - - L12
- - R21
- - - L18
- - - - L16
- - - - R20
- - - R22
- - - - R24

If we delete R21, we will loose R24

C10
- L5
- - L4
- - - L3
- - R8
- - - L6
- - - R9
- R15
- - L14
- - - L12
- - R22
- - - L18
- - - - L16
- - - - R20

With my fix you get this output. Note the position of R24

C10
- L5
- - L4
- - - L3
- - R8
- - - L6
- - - R9
- R15
- - L14
- - - L12
- - R22
- - - L18
- - - - L16
- - - - R20
- - - R24

Let me know if you need help replicating this on your end.

This is an issue with the barebones Unity plugin included in the main release, and not with the tango examples.

Assets/TangoSDK/Core/Scripts/Common/EventController.cs(48,39): error CS0117: AndroidHelper' does not contain a definition forParseTangoEvent'

Easy steps to get the error yourself:

1. Schur Tango Unity plugin @ https://developers.google.com/project-tango/downloads
2. Import into Unity 5.1.2
3. look in console for the import error above

Tango Application Crashes on rapid motion of the device.

Following the GVR Tango integration guide, I am able to get Tango working with the GVR sdk. Everything works as expected until I add the GVR Spatial Audio, which causes a crash on startup. I did temporarily get Spatial audio working with the native oculus package in unity, but it's definitely not as powerful and just does not feel as immersive as it should be. Any insight?

I'm not sure if I got the event in here, but here is a link to some log cat.

Thanks! Stoked on GVR!

Most of the time, the Unity SDK call to a native method during the connecting UX screen. The method is not found and the connecting screen hang out.

The problem is with the method:
tangoUxObject.Call("processPoseDataStatus", poseStatus);
But sometime it works.

My tango manager configuration is:

I also use the Tango Point Cloud Prefab.

Unity version: 5.1.0f3 Personal
Tango Unity SDK: von Mises

I experience issues with the original Project Tango Tablet; it has Android 4.4.2. and all the LATEST OS and software updates, including the Tango Core (Deprecated).

Most of the updated apps from Play Store are not working properly anymore, e.g. voxxlr and other that were working fine before the latest update I did...

For developing, I have

• Unity 5.6.f1

• Unity 5.3.7f1 (installed this previous one for trying out the previous Tango SDK from 2015...) - I'm using this one currently, but the 5.6.f1 built the app too in the end (after re-package issues etc.)

• Android SDK Platforms 23 (required by both versions of Unity 3D when I build; I tried lower - e.g. 19 but it didn't work...); 16, 17, 19 in Android SDK platforms (I downgraded everything hoping it will improve the apk build)

• Android SDK Tools 25.0.6

• latest Tango SDK (the one available on the main Tango site)

I'm doing exactly as in the tutorials (Tango Manager conf, etc.).

I checked the app permissions on the tablet and they look fine (access to camera, etc.)

I can finally build (after downgrading the Android SDK) but none of the example apps from the Tango SDK are working (e.g. white background for both Tango cameras - new and deprecated; no motion detected, etc.) The kitten example from the tutorial is not working either...

I tried the Simple AR tutorial - I see the sphere but it's not doing anything - no movement, no real scene from the camera. I switched to VR, but still NO MOTION.

All in all:
I have NO MOTION and NO REAL VIEW no matter the example or app I build.

I don't know if it is the latest OS installed on the Tango tablet, or what...

Back in 2015 it took a couple of minutes to do basic demos. Now I'm spending hours and hours to rollback SDKs etc.

PLEASE HELP:
I need:

• the previous configuration (Unity version, Android SDK versions, Tango SDK version) known to work fine with the Google Tango TABLET

Thanks,
Lucas

When recognize an area description,then Open Tango AR Camera,I want do this,What should I do?

That, I add a Tango AR Camera in MultiplayerCubeStacker scene,but Tips:

"TangoApplication has area descriptions enabled ,but use area description pose option is not selected.
if left as-is ,this script will use the start of service pose even if an area description is loaded and/or area learning is enabled."

And auto-connect does not supply a chance to specify an Area Description.
Why ?

Built application asks for exporting ADF file permissions and
areaDescription.ExportToFile(kb.text) in script ADMGUIController
returns true, but no file is written on desired location (/sdcard/file.adf or any other internal like /storage/emulated/0/somefile.adf)... Using Unity 5.6.1 and Lenovo Phab 2 Pro, clean project with most recent Tango package imported. Anybody experienced similar isue ?

Is it possible to change ADF file storage to some accessible folder ?

Thank You

At https://github.com/googlesamples/tango-examples-unity/blob/master/MotionTrackingUnity/Assets/Scripts/PoseController.cs, the camera transform is always reset to Identity no matter what the camera transform is set to in Unity beforehand. The original SampleController.cs script in older versions of Unity used the existing pose set in Unity. Could this be changed to work the same way?

I get this error when I open up the UnityProject from the latest SDK .unitypackage download (Okul) or when I open the UnityExamples project from this Github.

Indeed, the property "m_emulationTexIdCaptureTextures" does not exist in VideoOverlayProvider.cs, and that class does not extend another class so it seems like it's missing altogether.

When viewed from the third person view, there seems to be a misalignment between the camera's view and the point cloud's position. The screenshots are taken from a clean build from the latest master version.

When trying to run the TangoCardboardWithMeshing scene on device, i get the following exceptions.

I tried using unity 5.2.1f1 and 5.6.0f3

I noticed a significantly huge motion-to-photon latency when using the cardboard example. It's actually also noticeable with a normal Tango app. Motion-to-photon latency is quite critical for a good VR experience. Do you have data on this? Do you have plans to decrease it? Can we as developers try to decrease it?

Thank you.

Hello,
Does Unity SDK supports 2d-floor plan extraction just like in JAVA API for creating 2d maps for navigation using Project Tango

Hi,
