sceneform-android-sdk | Sceneform SDK for Android | Android library

This happened because implicitly the Factory based scene building contains CompletableFuture as well! More specifically the material building is a function which returns CompletableFuture.

Not realizing this, I haven't quoted the important code section in the question. You can see that the just below the Maze model loader instructions:

Well I finally got it. Took awhile and some serious trial and error of rotating every node, axis, angle, and rotation before I finally got it to place nicely. So I'll share my results in case anyone else needs this as well.

End Result looked like:

Of course it is mildly subjective to how you held the phone and it's understanding of the surroundings, but it's always pretty darn close to level now without fail in both landscape and portrait testing that I have done.

So here's what I've learned.

Setting the worldRotation on the anchorNode will help keep the 3DModel facing towards the cameraview using a little subtraction.

The documentation for Fragment.onCreateView() indicates the following:

This will be called between onCreate(Bundle) and onActivityCreated(Bundle).

The Android framwork makes all lifecycle calls itself.The Android framework will call onCreate() on the fragmentto initialize the fragment. At some later time, the Android framework will callonCreateView()` on the fragment. The following parameters are passed:

• LayoutInflater: The LayoutInflater object that can be used to inflate any views in the Fragment. The framework gets the LayoutInflater from the Activity's Context.

• ViewGroup: If non-null, this is the parent view that the fragment's UI should be attached to. The fragment should not add the view itself, but this can be used to generate the LayoutParams of the view. This parameter is the container View that holds the Fragment.

Bundle: If non-null, this fragment is being re-constructed from a previous saved state as given here. In this case, the Bundle contains the most recently saved state of the Fragment (ie: the data from the most recent call made to the Fragments onSaveInstanceState() method).

Regarding your other questions:

• If you define a method foo(), the Android framework would never call it. The Android framework has a specific set of defined methods that it calls on certain components (Activity, Service, BroadcastReceiver, Fragment, etc.) at specific times.

• The View returned from onCreateView() will be used by the Android framework. The documentation clearly indicates how the returned View object is used:

If you return a View from here, you will later be called in onDestroyView() when the view is being released.

Make the 3D model a child of the camera node, by making it a child of the camera node you are forcing it's position to update relative to the camera and not an anchor. Use local rotation to rotate the model.

[update]

You can also use sceneform as part of the app's layout.xml. In the layout.xml for the view, add the SceneView as part of the view's layout.

Ensure that you also export the texture (image file) that your 3D mesh requires. In my case, my sample-data directory looks like this:

After successful conversion of the 3D model into sfa/sfb file formats, you should then check on the samplers array in the sfa file that defines the textures your mesh is using.

Here's my end result:

Solution: It's not the Center pose, it's the AugmentedFaceNode from the face, which the values in the buffer given by getMeshVirtices() are relative to:

Not sure if this is what you looking for but try this it looks to me nightmare though it works i have tried it somewhere at the bottom page he will explain to you how to rotate the 3dobject look for this title "Bonus: Make the heart rotate!"

how to do rotatation animation in sceneform

Similar to set position cornerNode.setLocalPosition(localPosition); you can set rotation cornerNode.setLocalRotation(new Quaternion(90f, 0f, 0f, -90f));
