Saving and Displaying Spatial Mapping Mesh

GeneralPancake

Hi,
I'm trying to save the mesh created by the hololen's spatial mapping feature. What I want to do is the following

• Map the room for some period of time
• Save the mesh created by spatial mapping
• Display that mesh as a hologram, e.g. a miniature version of the map

I am aware that you can download the mesh as a .obj file from device portal, but I need to do this within a script.

What I have been trying, with limited success, is calling SpatialMappingManager.Instance.GetMeshes(), then drawing these meshes in a new gameobject.

The problem is, when I draw the meshes I capture from the spatial mapping manager, they draw as a completely unrecognizable, jumbled mess in a cube.

So I'm capturing something, but when I draw it the output is not at all what I'm expecting, and least of all a map of the room I'm in.

Here is some of the code I'm using:

 //this runs after mapping the room for some period of time. 
    if(stopCount == 1)
    {           
        stateDisplay.text = "Drawing";          
        spatialMeshes = SpatialMappingManager.Instance.GetMeshes();     

        meshCount = spatialMeshes.Count;
        meshCountDisplay.text = "Meshcount = " + meshCount;
        SpatialMappingManager.Instance.DrawVisualMeshes = false;
        //SpatialMappingManager.Instance.enabled = false; //Hopefully this turns off spatial mapping but who knows 
        for (int i = 0; i < meshCount; i++)
        {
            totalVerts += spatialMeshes[i].vertexCount;
            drawMesh(spatialMeshes[i]);
        }       
        vertCountDisplay.text = "Total Vertexes = " + totalVerts;
        totalVerts = 0;
        stopCount = 5; //So this block only gets run once. 
    }

}

  //This draws the meshes I'm capturing from spatial mapping 
public void drawMesh(Mesh meshIn)
{
    var spatialMesh = new GameObject();
    spatialMesh.AddComponent<MeshFilter>();     
    spatialMesh.AddComponent<MeshRenderer>();
    spatialMesh.GetComponent<MeshFilter>().mesh = meshIn;
    //spatialMesh.GetComponent<MeshFilter>().mesh.RecalculateNormals(); //I dunno if this will do anything useful 
    spatialMesh.GetComponent<Renderer>().material = material;       
    spatialMesh.transform.parent = meshObject.transform;
    spatialMesh.transform.position = meshObject.transform.position;
    spatialMesh.transform.localScale = meshObject.transform.localScale;     
}

Any advice or suggestions are appreciated. Thank you.
