Saving mesh from HoloLens emulator - 230

HoloJames · April 2016

I've been trying to save a .room file from the HoloLens emulator, as described in the 230 tutorial - https://developer.microsoft.com/en-us/windows/holographic/holograms_230

The tutorial uses an actual HoloLens, but I assume it should be possible from the emulator as well (using one of the loaded xef rooms in the emulator). I have been unable to get it to work (I'm thinking it might be a network thing). Has anyone tried this and been successful?

Get your meshes from the spatialmappingmanager
SpatialMappingManager.Instance.GetMeshes()

public static string Save(string fileName, IEnumerable<Mesh> meshes)
    {
        if (string.IsNullOrEmpty(fileName))
        {
            throw new ArgumentException("Must specify a valid fileName.");
        }

        if (meshes == null)
        {
            throw new ArgumentNullException("Value of meshes cannot be null.");
        }

        // Create the mesh file.
        String folderName = MeshFolderName;
        Debug.Log(String.Format("Saving mesh file: {0}", Path.Combine(folderName, fileName + fileExtension)));

        using (Stream stream = OpenFileForWrite(folderName, fileName + fileExtension))
        {
            // Serialize and write the meshes to the file.
            byte[] data = SimpleMeshSerializer.Serialize(meshes);
            stream.Write(data, 0, data.Length);
            stream.Flush();
        }

        Debug.Log("Mesh file saved.");

        return Path.Combine(folderName, fileName + fileExtension);
    }

    }

The code seems not working? my .obj file cannot show models

      using (Stream stream = new FileStream(Application.persistentDataPath+ "/Room.obj", FileMode.Create, FileAccess.Write, FileShare.None))
            {
                // Serialize and write the meshes to the file.
                byte[] data = SimpleMeshSerializer.Serialize(meshes);
                stream.Write(data, 0, data.Length);
                stream.Flush();
            }
