Is it possible to get part name of 3D Object?

[braver-tool]

Ques 1:
I have to added Human 3D object file using your excellent Renderer code,and the 3D object have multiple body parts(Head,Leg,etc..).So,Using OnTouch event can i have selected 3D model part name??

Ques 2:
Is it possible to load more than one Obj file at same time in a SurfaceView??

Thanks in Advance

You would have to implement a "picking" algorithm to transform your touch coordinates into the world space of the model and detect which portion of the model is picked.

Is it possible to load more than one Obj file at same time in a SurfaceView?

Sure, right now the model is stored as a global field in ModelViewerApplication.java. You can change this to be a List of models, and then render all of them in ModelRenderer.onDrawFrame().

I have to try with your tips for load more than one object file at same time in a surfaceview.But its not working for me.
Please help me!,If you have sample source pls share the link.
Please find below my Source

Step 1: Application class
   @Nullable
private List<Model> currentModel;

public static ModelViewerApplication getInstance() {
    return INSTANCE;
}

@Nullable
public List<Model> getCurrentModel() {
    return currentModel;
}

public void setCurrentModel(@Nullable List<Model> model) {
    currentModel = model;
}

Step 2: MainActivity
    List<Model> modelList = new ArrayList<>();
    try {
        InputStream stream = getApplicationContext().getAssets().open(SAMPLE_MODELS[0]);
        Model model = new ObjModel(stream);
        stream.close();
        modelList.add(model);

        InputStream stream1 = getApplicationContext().getAssets().open(SAMPLE_MODELS[1]);
        Model model1 = new ObjModel(stream1);
        stream1.close();
        modelList.add(model1);

        setCurrentModel(modelList);
    } catch (IOException e) {
        e.printStackTrace();
    }

Step 3: Rederer class

@OverRide
public void onDrawFrame(GL10 unused) {
GLES20.glClear(GLES20.GL_COLOR_BUFFER_BIT | GLES20.GL_DEPTH_BUFFER_BIT);

    floor.draw(viewMatrix, projectionMatrix, light);
    if (model != null) {
        for (int i = 0; i < model.size(); i++) {
            model.get(i).draw(viewMatrix, projectionMatrix, light);
        }
    }
}
