After zooming and/or tiling my view of our solar system, and then transitioning/clicking to a planet view or galaxy view, and then coming back to the solar system view, the zoom and tilt has been reset.

Customizing any view and browsing away and then returing causes the view to reset...

The card will not show until my gaze precisely on "UI_POI" Collider,is this normal?
but
when I use moveCube button to move the galaxy two or more times,the card shows when gaze UI don't move on the "UI_POI" Collider,gaze UI is On "UI_POI"'s left or right.
maybe my network reason,I can't upload my screenshot,so I use this link

This error is generated in Unity when building GalaxyExplorer for the first time causing the build to fail. However, subsequent builds of the project won't hit this error and successfully generate the Visual Studio Solution. Work-around is to simply build in Unity twice.

A HoloLens forum thread covers this error in more detail.

The complete error message is: "Broken text PPtr in file(Assets/SolarSystem/SolarSystem.prefab). Local file identifier (11493526) doesn't exist!"

I think these are part sun glow/flare as the orbiting bodies are re-used Sun assets.

When running on phone, the POI is difficult to select when running on the phone.
If the POI is moving towards the left when you select it, the POI card strafes across where the user tapped and remains visible. If, however, the POI is moving towards the right when you select it, the POI card quickly disappears as it continues on its rotation.

Two options I see:

1. First tap stops the Galaxy from rotating; Second tap, if on a POI shows the POI card otherwise the Galaxy starts rotating again (end), third tap navigates into the POI.
2. If the tap opens a POI, disable the POI closing until a second tap is recognized.

Project needs to move to Unity 5.4.0b14-HTP

Load b10 project into Unity b14
Build and deploy project for Windows Store
Commit changes to materials, shaders and Project Settings assets

reference #80  #59 and possibly #75. 

• Route touch/gesture/input events from desktop/slate/phone to the application\
• Implement equivalent of the app-bar menu for Reset and About
• Ensure the back-button affordance is still available.

On HoloLens, there is a "zoom" button to toggle into zoom mode. When GE is run on a non-HoloLens platform, the "zoom" button should be removed and that platform's native "zoom" gesture should be plumbed through the input manager.

The way it's currently animated, the Earth rotates 1 time for each Moon orbit - which makes the same side of the Earth always point to the Moon.

If you slow down the Moon's rotation rate to 1/2 and increase the Earth's rotation 2x, it wouldn't be as obvious that it's wrong.

The Earth actually rotates about 27 times on its axis for each complete Moon orbit around the earth. You don't need to do the full 27:1 ratio though, since this is not intending to be an astronomical model, but would be nice to have earth's rotation not be locked to the moon's orbit at least.

This is an amazing app, one suggestion have a better pin screen like RoboRaid.

I'm trying to build the project and I could not pass this error when trying to build it in Unity.

Here are my specs:
Windows 10 Pro
Unity beta version: 5.4.0b13
VS Community 2015 Upgrade 2

This is what I did:

1. Unzip the GalaxyExplorer
2. Open it with Unity [C:\Program Files\Unity 5.4.0b13]
3. When building with these settings: Windows Store ---> SDK: Universal 1.0, UWP Build Type: D3D, Build and Run on: Local Machine
   Here are some of the errors that I encountered:

Assets/Scripts/Input/GazeSelectionTarget.cs(4,22): error CS0234: The type or namespace name WSA' does not exist in the namespaceUnityEngine.VR'. Are you missing an assembly reference?

Assets/Scripts/Input/HandInput.cs(6,22): error CS0234: The type or namespace name WSA' does not exist in the namespaceUnityEngine.VR'. Are you missing an assembly reference?

Assets/Scripts/Input/InputRouter.cs(7,22): error CS0234: The type or namespace name WSA' does not exist in the namespaceUnityEngine.VR'. Are you missing an assembly reference?

Any clues are helpful. Thanks!

Hi, I am receiving this error in unity's console:

NullReferenceException: Object reference not set to an instance of an object
IntroductionFlow.Start() (at Assets/Scripts/IntroductionFlow.cs:93)

https://github.com/Microsoft/GalaxyExplorer/blob/master/Assets/Scripts/IntroductionFlow.cs#L92

     92:   ViewLoader.Instance.CoreSystemsLoaded += CoreSystemsLoaded;

I have not touched the cloned repo, I am using Unity 5.5.0f3.

Instead of having each contributor narrate, it might be better to have a single default narrator, preferably Cortana

These POIs and their cards are grouped a bit too close together. They should be spread out some so they are easier to select.

On HoloLens, GE has a "tilt" button. When GE is not running on a HoloLens, the "tilt" button should be removed and a "well-thought-out" rotate gesture should be plumbed through the input manager.

Since I don't have a HoloLens unit yet. But thinking that UWP apps should work across Windows 10. Would it be a lot of work to convert GalaxyExplorer to XB1?

Has anyone given this a shot?

I am trying to complete the building step, but it says that I need to fix some compile errors in the scripts, even though, I did not mess with code in the scripts. I also I do not know how to look for the errors in the scripts. I am using Visual Studio 2015 as my editor and I don't see any errors.

This strange error occurs when building GalaxyExplorer in Unity, but it doesn't cause the build to fail and doesn't appear to have any impact on Galaxy Explorer.

Complete error message is: "Component MonoBehaviour could not be loaded when loading game object. Cleaning up!"

Below I made Jupiter and the four Galilean moons https://en.wikipedia.org/wiki/Galilean_moons. How to import 3D material for these moons?

Hello, HoloLens team
I met several problems while building the Galaxy Explorer project:

1. From Unity, in Build Settings window. I could not find:
   1.1 "any device" as the Target device
   1.2 "Copy References" to check

If I ignore and continue, when I build output C# project in VS 2015, the 2nd problem happen:
2. "UnityPlayer", "AppCallbacks" and "WinRTBridge" assembly reference could not be found
but I can find them in corresponding folder C:\Program Files\Unity HoloLens 5.4.0f3-HTP\Editor\Data\PlaybackEngines\MetroSupport\Players\UAP\

I am using Unity Technical Preview version HoloLens 5.4.0f3-HTP from Microsoft guidance. When open C# project it prompt me the version is not match need to re-import...

If I add manually to those assembly reference, VS 2015 prompt me "A reference to ....dll could not be added. Please make sure that file is accessible..."

Could you guys help me out of here?

Thank you

The SphereCast is currently using GazeDistance as the radius for the sphere to cast. This defaults to a sphere that has a 30m radius.

Fix: Calculate the sphere's size at GazeDistance based on GazeSpreadDegrees and cast that instead.

I receive an error when trying to load the GalaxyExplorer in Hololens emulator.

Supplied PxGeometry is not valid. Shape creation method returns NULL.
(Filename: C:/buildslave/physx/build/Source/PhysX/src/NpFactory.cpp Line: 675)
The program '[3624] GalaxyExplorer.exe' has exited with code -1 (0xffffffff).

I followed the instructions in the channel 9 tutorial, with the exception that I git cloned the project, instead of downloading a zip. The emulator starts, 'pinning Earth to the middle of the room', it starts to zoom out to the solar system, video freezes (its cold in space!) right after 'is part of an even bigger picture', and throws the error above. Using HoloLens Emulator 10.0.11082.1039.

The POI target for S2 is inconsistent with the targets for other POIs. It needs to be moved up along the Y axis a bit.

Per ChimeraScorn's comment:

I finally succeeded in installing the app! Here are my preliminary comments. I know the developing team had done a marvelous and wonderful job, so my comments below should be taken with a giant grain of salt!

Overall downloading and installation (on PC):
The process was not straightforward due to multiplicity of files that had to be downloaded / installed. Also, the fan of my computer ran very rapidly and noisily several times during the installation process. Maybe I need to upgrade my graphics card! I wonder about the HoloLens handling of the files.

Scenes/Views/SunView:
Very beautiful. However, the sun was very far and I was unable to zoom in on it! Totally missed this experience :(

Scenes/Views/MercuryView:
Very beautiful and elegant. Smaller shadow might be better.

Scenes/Views/VenusView:
Same as above.

Scenes/Views/EarthView:
Excellent realistic animation of Earth and Moon! However, the animation showed spots on Earth when I zoomed out. No such spots on the moon, though. Likely due to "patches" of earth changing / being replaced by other patches as the earth rotates. Mouse did not allow easy manipulation.

Scenes/Views/MarsView:
Marvelous animation. However, important geologic structures (e.g. Olympus Mons, polar caps and Equatorial canyon) need to show more prominently. Same for Mars’ moons.

Scenes/Views/JupiterView:
Awesome animation and sounds. Are those real sounds or artistic? Also, at least the Galilean moons need to show! Finally, having smaller shadow would be more attractive.

Scenes/Views/SaturnView:
Very nicely pictured although adding some moons and movement would be better.

Scenes/Views/UranusView:
Nicely done although adding some moons / smaller shadow would be better.

Scenes/Views/NeptuneView:
Nicely done although adding some moons would be better.

Scenes/Views/PlutoView:
Very nicely textured although adding the moons would be better.

Scenes/Views/SolarSystemView:
Very beautiful, especially respect of orbital velocity. However, number of asteroid belt objects needs to be increased / size reduced / blurred.

Scenes/Views/GalaxyView:
Beautiful! However, more detail might be needed. Diffraction spikes show on some stars but not all https://en.wikipedia.org/wiki/Diffraction_spike#/media/File:NGC6397.jpg There are (i) arrows and circles pointing to orbits. Finally, shape of galaxy / color and shapes of stars / nebulae / clusters / constellation outlines might be needed.

Excellent work!

Does anyone know when (year) that the solar system begins in the animation?

The current content in the phone branch should be pulled into master as it is not strictly phone specific.

We should add Spectator View to Galaxy Explorer.

1. Why was the app developed using Unity rather than Visual Studio?

2. Can the app run from within Visual Studio?

3. Will development of HoloLens apps in the future always be done via Unity?

4. Does Unity allow stepping into scripts?

5. What is the best / easiest way to debug the scripts?

6. Since the objective of the app is teaching programming, will the team publish YouTube videos showing how the app was developed and how the code works?

Hi,
the selection of POIs and the Tools don't work in the newest version of Galaxy Explorer in Unity 5.5.0f3. Same goes for the Hololens Emulator. It works in the Hololens itself.
It works with the Commit a4f6c23 from Nov. 8th in Unity 5.5.0f3.
Greetings!

Please compile the appx and place it under the "releases" tab for quicker deployment.

Why do it need to store event handler to the private event (_coreSystemsLoaded) before the Core system loaded?

The tools menu does not function as you gaze (or when you press the keyboard on a pc) in 5.5b11.

Once you've navigated into our SolarSystem from the Galaxy view, it is really difficult to select a POI other than the Sun.

Hello,

When deploying the GalaxyExplorer application to the Hololens emulator, I get a System.AccessViolationException in the TransitionManager's PrevSceneLoadedCoroutine method. More specifically, this occurs on line 507, when the application is setting all of the found collider's enabled value to true. However, this occurs only when the application is transitioning to the GalaxyView state (line 186 of IntroductionFlow.cs). All instances of setting the collider.enabled value before this point do not throw the exception. Additionally, this problem does not occur when running the application in Unity; only when running the emulator via Visual Studio 2015.

This error message is generated by Unity while building GalaxyExplorer, but doesn't appear to have any impact on the build.

A thread on the HoloLens forums discusses this issue.

Dear Microsoft GalaxyExplorer team,
I am Tatsuro Ueda, Japanese.

Nice to meet you.
I was a teacher for ten years and now I am developing a science
learning application.
I am planning to visit junior high school and high school,
and to teach an hour class using HoloLens.
For the time being, I am thinking to try classes for free until the
end of March next year.

In these lessons, I would like to use GalaxyExplorer in addition to
HoloMagnet3 I developed.
I would be pleased if you grant permission.
Thank you very much.

In addition, I will carry out a simple questionnaire survey at the end
of the class.
If you grant permission, I think that I can send you the impression of
GalaxyExplorer.

Best regards
Tatsuro Ueda

Sorry I am a newbie here. But I have a question to load this assets in Unity.

I have dowloaded this file and imported to unity, I have unity 5.5.0f2.

However, when I opened the folder, I can't see the '.unity' file, and can't build the project.

Can someone help me with the guidance?

Thanks so much in advance!

Unable to download the Galaxy explorer app. Now during the third attempt, it got struck at 47% for the past 1 hour. How long does it really take to download this?. Please advise

It would be incredibly helpful to have a tool that, given two strings for input, automatically spits out a .PNG file for the POI card.

I can make this. How to progress and make it look like the earth-moon animation?

starting from here?

i have 2 problems
1 Component could not be loaded when loading game object. Cleaning up!
2 Transform component could not be found on game object. Adding one!

how to solve it ?

These files need to be updated to use relative instead of absolute paths

• UWP/GalaxyExplorer.sln
• UWP/GalaxyExplorer/GalaxyExplorer.csproj

This method was added to temporarily work around a Unity bug.

https://github.com/Microsoft/GalaxyExplorer/blob/c40dac423b00164627f123e934e6570065a5d56f/Assets/SolarSystem/OrbitalTrails/OrbitalTrail.cs#L68

That bug is slated to be fixed in 2017.2.0p1.
