A Hololens application to increase your situational awareness. Using OpenStreetMap data, it renders the world. You can share a session with multiple users, editing layers of information. Even though we can share our world, different users can display different layers of information. Is it based on MapzenGo, to render 3D worlds as hologram. Video 1, Video 2.

• Render the world based on open data
• Collaborative: users can join a session and share their world. Also, you can edit layers together.
• Navigate the world using your browser: you can update your location using a web browser. See the world-explorer-server for more information on this.
• Show 3D models of the world
• Voice commands
  • switch to [NAMED_VIEW]: in the config.json, the views are defined
  • toggle buildings | roads | water | [LAYER_NAME]: toggle the visibility of the buildings. etc.
  • zoom in | out
  • increase | decrease range: increase or decrease the displayed area
  • move north | south | east | west | north east | etc. : move one tile in that direction
  • show | hide commands: displays a HUD with some of these commands
  • place: when an item is selected, places the item
  • clear cache: clears the local cache

Also see the Lessons Learned section in the Wiki, which contains some tips to develop Hololens applications for Unity.

First, make sure that you can run the local tile server. See the build instructions in the world-explorer-server folder.

• Open project in Unity (for Hololens, of course). Currently, I'm using a Beta version of Unity, v5.5f03.
• Import the MainScene from Assets\Scenes. Please check that the Main camera has a black solid color background.
• Press CTRL-B (Build project), and:
  • adjust the build settings (Windows Store project, SDK: Universal 10, Target device: Hololens, UWP: D3D, C# project).
  • open the menu Player Settings and check that in Other Settings, the Virtual Reality SDK is set to Hololens.
  • Run build: create a new Folder (I called it App - please do it too, as this folder should be ignored in Git), and let it run.
• Open the newly created Visual Studio solution in the App folder, set the build to Release | x86 | Hololens Emulator (or device), and press Ctrl-F5

NOTE: In Initialize.cs, we specify the config.json that is loaded. Please replace this with a version of your own, as the IP addresses of tile server and MQTT server will certainly not match yours!

In order to show 3D models, you need to create an asset bundle that contains these models. Currently, I do the following:

• Go to 3dwarehouse.sketchup.com and download your models
• Create a new Unity project
• Optionally, if you cannot open them in Unity, or the model has a terrain: Open them in Sketchup, e.g. to remove the underground (unlock the model), and save them as Sketchup 2015 project
• Import the model into Unity (menu Assets|Import New Asset...): in the inspecter, underneath the image, specify a name for the asset bundle (e.g. buildings/eindhoven). If you don't specify the name, it won't be exported. Also note the geo location in the inspector, which should be used in the assets.json file in the world-explorer-server project folder.
• Optionally, change the model name, as this is how you load it from Unity: e.g. I only use lowercase names.
• Import all models until you are done.
• In the Assets folder, create a new folder named AssetBundles (the name used in the script below).
• Create a script with the following content: it will add a new command, Build AssetBundles, to the Assets menu. Click it to build your asset bundle. You will find your asset bundle in the created folder. Copy it to world-explorer-server assets folder (or any FTP server) to use it.

#if UNITY_EDITOR
using UnityEditor;

public class CreateAssetBundles
{
    [MenuItem("Assets/Build AssetBundles")]
    static void BuildAllAssetBundles()
    {
        BuildPipeline.BuildAssetBundles("Assets/AssetBundles", BuildAssetBundleOptions.None, BuildTarget.WSAPlayer);
    }
}
#endif
