Tutorial

Install the tools に続いて、Using Visual Studio を確認したところ、下記の下準備が必要であることを確認。

Prerequisites

  1. See Install the Tools for installation instructions.
  2. Create a new Universal Windows app project in Visual Studio 2015 Update 1 for a 2D Windows 10 app or start use Unity to create a holographic app. C#, C++, and JavaScript projects are all supported on HoloLens.

 

この記事は、2. の use Unity to create a holographic app (a.k.a Holograms 100) の作業過程記録です。

 

  1. Target the app to Windows.Holographic新しいプロジェクトの作成 (Chapter 1 - Create a New Project の実施)
    1. Start Unity
    2. Select New
    3. Enter a project name (e.g. "HelloHolograms")
    4. Enter a location to save your project
    5. Ensure the 3D toggle is selected
    6. Select Create project

  2. Chapter 2 - Setup the Camera の実施
    1. Select Main Camera in the Hierarchy panel
    2. In the Inspector panel, find the Transform component and change the Position from (X: 0, Y: 1, Z: -10) to (X: 0, Y: 0, Z: 0)

    1. In the top left corner of the Hierarchy panel, select the Create dropdown and choose 3D Object > Cube.

      f:id:hololensdev:20160816233221p:plain

    2. Select the newly created Cube in the Hierarchy panel
    3. In the Inspector find the Transform component and change Position to (X: 0, Y: 0, Z: 2). This positions the cube 2 meters in front of the user's starting position.
    4. In the Transform component, change Rotation to (X: 45, Y: 45, Z: 45) and change Scale to (X: 0.25, Y: 0.25, Z: 0.25). This scales the cube to 0.25 meters.f:id:hololensdev:20160816233445p:plain
    5. To save the scene changes, select File > Save Scene, name the scene, and select Save
  6. Chapter 4 - Export from Unity to Visual Studio の実施

        あれこれやったが、うまくいかない。バージョンが違うのに進めたせいか。再度作りなおすか。
        Unity が Version 5.4.0f3-HTP Personal であることを確認のうえ、上記手順を再度実行。

        できた。
