ARFragment 和 GLSurfaceView 在一个 Activity 中兼容吗？

Question

我正在尝试在我的 Android 应用程序中将 ARCore 示例 - hellosceneform 和 augmented_image_java 合并为一个 Activity。也就是说，可以触摸屏幕并放下 AR 对象，也可以让相机扫描它识别的对象，并在对象周围放置一个 AR 框架。请帮忙？

Answer 1

Sceneform 在 SceneView class. This makes it incompatible with GLSurfaceView. You can do what you are looking to do by combining the hellosceneform sample and the augmentedimage 示例中实现了自己的渲染引擎，它们都使用 Sceneform。

要合并两者，从AugmentedImageActivity.java开始，添加模型的成员变量：

private ModelRenderable andyRenderable;

您还需要安迪的模型。

然后在onCreate中，在onCreate()末尾加入模型的加载和敲击的处理：

   @Override
    protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);

      arFragment = (ArFragment) 
      getSupportFragmentManager().findFragmentById(R.id.ux_fragment);
      fitToScanView = findViewById(R.id.image_view_fit_to_scan);
   arFragment.getArSceneView().getScene().addOnUpdateListener(this::onUpdateFrame);

    /*** Add HelloSceneform functionality here vvvvvvvvv **/

    // When you build a Renderable, Sceneform loads its resources in
    // the background while returning a CompletableFuture.
    // Call thenAccept(), handle(), or check isDone() before calling get().
    ModelRenderable.builder()
            .setSource(this, R.raw.andy)
            .build()
            .thenAccept(renderable -> andyRenderable = renderable)
            .exceptionally(
                    throwable -> {
                      Toast toast =
                              Toast.makeText(this,
                             "Unable to load andy renderable", Toast.LENGTH_LONG);
                      toast.setGravity(Gravity.CENTER, 0, 0);
                      toast.show();
                      return null;
                    });

    arFragment.setOnTapArPlaneListener(
            (HitResult hitResult, Plane plane, MotionEvent motionEvent) -> {
              if (andyRenderable == null) {
                return;
              }

              // Create the Anchor.
              Anchor anchor = hitResult.createAnchor();
              AnchorNode anchorNode = new AnchorNode(anchor);
              anchorNode.setParent(arFragment.getArSceneView().getScene());

              // Create the transformable andy and add it to the anchor.
              TransformableNode andy = new TransformableNode(arFragment.getTransformationSystem());
              andy.setParent(anchorNode);
              andy.setRenderable(andyRenderable);
              andy.select();
            });
  }

增强图像片段关闭了平面发现，因此您需要删除该代码以便渲染平面。此代码在 AugmentedImageFragment.java 中。只需删除这些行：

// Delete these lines to keep the plane discovery.
getPlaneDiscoveryController().hide();
getPlaneDiscoveryController().setInstructionView(null);
getArSceneView().getPlaneRenderer().setEnabled(false);
