我正在尝试在我的Android应用中将ARCore示例-hellosceneform和extendeded_image_java结合在一起,成为一个Activity。也就是说,可以触摸屏幕并放下AR对象,也可以触摸相机以扫描其识别出的对象并将AR框放在例如对象周围。请帮忙?
最佳答案
Sceneform在SceneView类中实现其自己的呈现引擎。这使其与GLSurfaceView不兼容。您可以通过组合同时使用Sceneform的hellosceneform样本和augmentedimage样本来完成您想做的事情。
要合并两者,请从AugmentedImageActivity.java开始并添加模型的成员变量:
private ModelRenderable andyRenderable;
您还需要Andy的模型。
然后在onCreate中,在
onCreate()
的末尾添加模型的加载和轻敲的处理: @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();
});
}
增强的图像片段会关闭平面发现,因此您将要删除该代码,以便渲染平面。该代码在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);
