我想在使用Rajawali框架的android應用程序中顯示3d對象。我使用Autodesk 3DS MAX創建了一個3D對象。 (我已經閱讀過推薦使用攪拌器的文章,但是我下載了一個我想用的模型和它的.3ds文件)在Android中使用Rajawali不顯示.obj

我把.obj和.mtl放在原始文件夾中(重命名文件如在mymodel_obj和mymodel_mtl推薦),然後我創建渲染器類:

public class Renderer extends RajawaliRenderer { 

private Context context; 
private Object3D mObject; 


//constructor 
public Renderer(Context context) { 
    super(context); 
    this.context = context; 
    setFrameRate(60); 
} 

@Override 
protected void initScene() { 
    try { 
     LoaderOBJ objParser = new LoaderOBJ(context.getResources(),mTextureManager, R.raw.denture_obj); 
     objParser.parse(); 
     mObject = objParser.getParsedObject();  
     getCurrentScene().addChild(mObject); 
    }catch (ParsingException e){ 
     e.printStackTrace(); 
    } 
} 

@Override 
public void onOffsetsChanged(float xOffset, float yOffset, float xOffsetStep, float yOffsetStep, int xPixelOffset, int yPixelOffset) {} 

@Override 
public void onTouchEvent(MotionEvent event) {} 
} 

我想顯示在一個片段中的模型。這是片段:

public class VisualizationFragment extends Fragment { 

private IRajawaliSurface surface; 
private Renderer mRenderer; 
private final static String TAG = "VFRAG"; 

@Nullable 
@Override 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { 
    super.onCreateView(inflater, container, savedInstanceState); 
    View v = inflater.inflate(R.layout.visualization_frag, container, false); 
    mRenderer = new Renderer(getActivity()); 
    applyRenderer(v); 
    return v; 
} 

protected void applyRenderer(View v) { 
    surface = (IRajawaliSurface) v.findViewById(R.id.brush_surface); 
    surface.setSurfaceRenderer(mRenderer); 
} 
} 

當我開始我的應用程序只是得到一個黑色的背景,沒有任何模型和以下錯誤:

11-25 20:33:19.677 3187-3201/com.example.marti.ibrush E/Rajawali: Getting location of uniform: uModelMatrix returned -1!

11-25 20:33:19.689 3187-3201/com.example.marti.ibrush E/Rajawali: Getting location of uniform: uTime returned -1! 

我也試圖在我的模型導出的3DS格式,然後將其導入攪拌機,然後再以.obj格式導出。但它也不起作用。 我已經注意到以下出口法規: https://github.com/Rajawali/Rajawali/wiki/Tutorial-17-Importing-.Obj-Files 但我找不到「攪拌器中的」包括法線「選項,所以我選擇了」寫入法線「。

在你的代碼,我想你需要添加燈和照相機下initScene()

在攪拌器,出口之前,我建議,以確保底層的紋理圖像文件名是中小盤。 導出時,請選擇「Strip Path」選項。

記得將紋理圖像文件複製到您的應用程序項目下的res \ drawable文件夾中。
