我想使用Rajawali框架在android应用程序中显示3d对象。我使用Autodesk 3DS MAX创建了一个三维对象。(我读过一些文章,建议你使用搅拌机。但我下载了一个我想使用的模型,它是一个.3ds文件)
我将.obj和.mtl放在raw文件夹中(按照mymodel_obj和mymodel_mtl中的建议对文件进行了重命名),然后我创建了一个渲染器类:
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) {}
}我想以片段的形式显示模型。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);
}
}当我启动我的应用程序时,我只得到一个黑色的背景,没有任何模型,并出现以下错误:

在您的代码中,我认为您需要在initScene()下添加灯光和摄像头
在Blender上,在导出之前,我建议确保底层纹理图像文件名为小型大写。导出时,请选择“条带路径”选项。
记住将纹理图像文件复制到应用程序项目下的res\drawable文件夹。
