Unity3D With Azure Blob Storage

This client example usage is for AR Sphere.

Here, you can see a Unity demonstration that utilizes Azure Blob Storage to stream and display a 3D model at runtime.

Using BlobModel

BlobModel.cs is a mini-library that helps you download a .obj file to later display it, at runtime, on the SampleScene. Note: the demo uses a cat.obj that I uploaded onto Azure. Any .obj file should work as long as the mesh isn't too complicated.

• Loading at runtime is difficult for .fbx files; more resources are available for .obj files
• Downloads will automatically be stored in ./Assets/Resources/
• Downloads should be awaited, so that the file can properly be downloaded before being imported
• Rendering is possible without adding a material, so don't worry about that while testing

Instantiation:

BlobModel bm = new BlobModel("fileNameOnAzure.obj", "ContainerItIsIn", connectionString);
...
await bm.download("fileNameToSaveAs.obj");

Sample usage:

BlobModel bm = new BlobModel("cat.obj", "example", cxnstr);
if (await bm.exists())
{
    await bm.download("catmodel.obj"); 
    Debug.Log("Downloaded.");

    Mesh meshHold = new Mesh();
    ObjImporter newMesh = new ObjImporter();
    meshHold = newMesh.ImportFile("./Assets/Resources/catmodel.obj");
    Debug.Log("Imported");

    GameObject myCat = new GameObject();
    MeshRenderer meshRenderer = myCat.AddComponent<MeshRenderer>();
    MeshFilter filter = myCat.AddComponent<MeshFilter>();
    filter.mesh = meshHold;
                                    //./Assets/Resources/metal01.mat
    Material catMaterial = Resources.Load("metal01", typeof(Material)) as Material;
    myCat.GetComponent<MeshRenderer>().material = catMaterial;

    Instantiate(myCat);
    myCat.transform.position = new Vector3(47, -365, -59);

    Debug.Log("Done");
}

That provides an output with a cat!

Why it works

To get started, read below on how you can log to a text file.

To use WindowsAzure.Storage, download the .unitypackage using NuGet2Unity, or from here.

The cube rendered on the screen runs the script Program.cs.

The connection string can typically be found on your Azure Portal. Input your connection string into the InputField, and hit Return. This calls a method that connects to the Blob storage using the connection string.

In the sample code, a container called example is created, where log.txt is read and updated to append the current date/time. Pretty cool!

Open up Microsoft Azure Storage Explorer to see the result below.
