我想在使用Rajawali框架的android应用程序中显示3d对象。我使用Autodesk 3DS MAX创建了一个3D对象。 (我已经阅读过推荐使用搅拌器的文章,但是我下载了一个我想用的模型和它的.3ds文件)在Android中使用Rajawali不显示.obj
我把.obj和.mtl放在原始文件夹中(重命名文件如在mymodel_obj和mymodel_mtl推荐),然后我创建渲染器类:
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) {}
}
我想显示在一个片段中的模型。这是片段:
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);
}
}
当我开始我的应用程序只是得到一个黑色的背景,没有任何模型和以下错误:

我也试图在我的模型导出的3DS格式,然后将其导入搅拌机,然后再以.obj格式导出。但它也不起作用。 我已经注意到以下出口法规: https://github.com/Rajawali/Rajawali/wiki/Tutorial-17-Importing-.Obj-Files 但我找不到“搅拌器中的”包括法线“选项,所以我选择了”写入法线“。
