Brief description of issue: I followed the instructions for the Mira Live Preview and was trying to do marker tracking. Unfortunately it does not work to track the marker when running both the WikiMiraTemplate and the Tracking tutorials. I get an error in the console in Unity which says "The current platfrom (OSXEditor) is not supported by the Wikitude Unity Plugin". The head tracking works well as I rotate my head I see both the editor and the phone content changing, however the spiral is never displayed when the marker is visible. The app works if not run in live preview.

All the instructions you had regarding the quality https://developer.mirareality.com/docs/mira-live-preview#section-configuring-quality-settings-to-use-live-preview were already setup and also the metal was already disabled.

I would like to track multiple markers in the same scene and I am having some difficulties understanding the tracking and hierarchy logic on your getting started documentation.

What I would like to do is to have one Mira marker to be tracked and define the origin of the coordinate system (as in your basic example, as I understood it), and then I would like to track another marker and just obtain the pose of my head relative to that second marker. What would be the proper way to achieve this?

Thanks for the help!

Hi,

When running in live preview the content appearing on the iphone looks quite pixelized. I was wondering if that is normal even if one follows the quality level instructions explained here https://developer.mirareality.com/docs/mira-live-preview or did I set something wrong?

When building or running a Unity project with the Mira SDK, there is an unreachable code warning for Assets/MiraSDK/Scripts/EventSystem/MiraInputModule.cs.

This issue was found on:

• Mira Unity SDK version number: 0.7.1
• Unity version number: 2018.1

How to reproduce the issue:

1. Build a Unity project with the Mira SDK included

This was noted as part of this pull request, but it's not immediately clear what the desired behavior is here. It's possible that the return statement is meant to be part of the if block, or maybe the early return is there to prevent an issue noted during development.

.../Assets/MiraSDK/Scripts/EventSystem/MiraInputModule.cs(13,13): Warning CS0162: Unreachable code detected (CS0162) (Assembly-CSharp)

Brief description of issue: The GettingStarted page has unclear instructions.

This issue was found on:

• Mira Unity SDK version number: 0.7.1? I cloned Master on 31 July 2018 https://github.com/miralabs/mira-unity-sdk
• Mira headset version: N/A
• Unity version number: 5.6.1f1
• Phone model and OS version number: N/A
• XCode Version number: N/A

How to reproduce the issue:

1. The Getting Started section says "Import the Mira SDK." I have cloned the latest to my computer, but Unity has no "import" option. Instead, I opened the root folder that I cloned in Unity SDK.

Q1: Was it correct to open the root folder of the Mira SDK in Unity?

2. The next step says: "Configure Player Settings: In the Unity top toolbar, select Mira -> Settings -> and then apply each recommended setting". Unfortunately, I don't seem to have the "mira" option in my Unity top toolbar (or anywhere on my screen): https://www.dropbox.com/s/cc4wlmjys3vmpyd/Screenshot%202018-07-31%2015.16.43.png?dl=0

Q2: How do I actually apply the recommended settings?

Brief description of issue:
No custom images can be implemented and then recognized on runtime. Target tracking works with default images as long as the MiraTrackers.wtc file hasn't been added to, but adding new targets and creating new .wtc files (and trying to use them) results in non-responsive runtimes and builds.

This issue was found on:

• Mira Unity SDK version number: 0.6.0, 0.7.0, 0.7.1
• Mira headset version: For the iPhone 6, 6s, and 7
• Unity version number: 2017.2.0f, 2017.3.0f
• Phone model and OS version number: iPhone 6 OS 11.2.6
• XCode Version number: 9.2 (9C40b)

How to reproduce the issue:

1. Load any new image into the WTC Editor.
2. Modify size as appropriate.
3. Build or run Live Preview and test target recognition (if you don't get a SIGABRT on a random thread citing an NSRangeException).

Additional comments:

XCode will show a SIGABRT on differing threads citing an NSRangeException or the like.

Hi,

I would like to track a 3D marker (e.g. a cube) instead of 2D. An example of the marker that I would like to track can be found here https://github.com/qian256/HoloLensARToolKit which I have been previously tracking with a Hololens. I tried looking into Wikitude and see if they would support this (so it could be used with Mira as well) but wasnt really able to find anything on this. It would be great to know if anyone has seen already something on this.

Thanks a lot for the help!

Brief description of issue:

Hi, I was now trying to add a custom marker to the WikiMiraTemplate.Unity scene. I followed the online instructions and in Unity went to Window/WTC Editor and then added my custom marker (png image) where I confirmed that the dimensions of the marker in the png image are the same as the printed marker - in GIMP it says that the print size is 80 mm width which is the same as the printed marker - and added it to "MiraTrackers". Then went to the MiraTracker gameobject and checked that it appeared there and set my custom marker to "active" (all others active as well).

If I run the example (not using preview), the original Mira marker gets properly detected and the spiral is displayed. If I then put my custom marker, the spiral is displayed but it is displayed not on top of my marker but very close to my eyes (becomes very large) and the movement of the spiral follows the movement of the marker (I rotated it by hand and the spiral rotates in the same way). Any idea why the spiral display would not be the same for my custom marker as it is for the original Mira marker?

Another thing is that if I click to "preview" for some reason the marker is not displayed in the scene, while the original Mira markers are.

I also noticed now that when opening the "Mira_Beta_Small.png" in GIMP it says that the print size of the image is a square of 361.24 mm width but that is not the size of the printed marker, which is 133.0 mm. Is this correct? Does this mean that there is a difference between the size of the printed marker and the print size of the png image?

Thanks!

Hi,

I was wondering if there was any simple way to access the camera stream when running one of your applications?

Hi,
there's a long time ago since the last update. Is this project dead?
Thx forward for reply.

The Transition2D script doesn't seem to automatically detect landscape when the phone's rotation starts off in landscape. I'm having to rotate to portrait and then back to landscape in order for it to transition.

It also doesn't seem to automatically detect landscape when the device is locked in portrait like the Google Cardboard app.

I'm on 2017.1.0f3
