But my 3d model is rendering above the head.
I also tried making the pivot point of my model same as that of canonical_face_mesh.fbx, (as mentioned in this SO question) but still when running in app it's rendering...
ANSWERAnswered 2019-Oct-01 at 11:41
The problem was
- I was not placing custom meshes as children of the asset node as mentioned in doc.
To make the custom mesh or the object a child of the asset node:
(Note: Every SDK has its own reference face mesh and they differ; make sure you use correct one).
ii) Then load your custom 3D model.
iii) Scale and align your model according to the canonical face mesh wherever you want it to be.
iv) In object mode press
ctrl + shift +p and then click your custom model and then click the bones present in canonical face mesh.A selection menu will appear select object in that menu.
This will make your model, the child of the asset node.
- Now you need to add Vertex Group in your model. To do so:
i) Select all vertex in your model in edit mode.
ii) Then go to context object data menu. Click the + icon and name your Vertex ( NOSE_TIP, FOREHEAD_RIGHT, or FOREHEAD_LEFT ). This you have to assign according to your model. Mine is Nose Pin so i choose NOSE_TIP. Then Click assign.
Now to cross check you can deselect your model and then click your vertex group and click on select button next to assign button you will notice that your model is selected now.
- You need to add modifier. To add modifier
i) Click on the modifier option.
ii) Then click add modifier you will see a drop down menu in that select armature.
iii) Name it as asset as shown above select object as asset and select Nose_TIP as shown above.
Now Delete only the facemesh from the asset.
and import your model.
I'm tinkering with the Sceneform SDK's Augmented Image sample code after I completed the accompanying code lab. The completed sample adds two types of objects to the AR scene: one is modeled with a CAD software and loaded from an
sfb binary (that's the green maze) and the other one is a red ball which is constructed run-time using the
A simple experiment is to remove the green maze to only have the red ball (and remove the physics engine of course as well). In that case however the red ball does not appear on the AR scene.
The interesting thing is that the green maze does not have to appear on the scene - by that I mean I don't have to create the

This happened because implicitly the Factory based scene building contains
CompletableFuture as well! More specifically the material building is a function which returns
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:
I've been getting my butt kicked trying to get a vertically placed 3d model GLB format placed properly on a vertical surface.
Just to be clear, I am not referring to the difficulty of identifying vertical surface, that is a whole other problem in itself.

I am using a fragment that extends ARFragment....

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.
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 fragment
to initialize the fragment. At some later time, the Android framework will callonCreateView()` on the fragment. The following parameters are passed:
LayoutInflaterobject that can be used to inflate any views in the
Fragment. The framework gets the
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
LayoutParamsof the view. This parameter is the container
Viewthat holds the
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
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.
onCreateView()will be used by the Android framework. The documentation clearly indicates how the returned
Viewobject is used:
If you return a View from here, you will later be called in
onDestroyView()when the view is being released.
I'm building an AR navigation app and I'm not really familiar with AR aspect of it. Is it possible to place an object in a static position for example in a corner of the screen?
I based my app on the sceneform example from Google: https://github.com/google-ar/sceneform-android-sdk/tree/master/samples/hellosceneform. I already imported the 3D-Model I want to use. Currently the app is looking for anchors on which you can place the object. I just want to place a navigation arrow in a corner of the screen, the arrow should still be able to rotate though.
I already searched for examples or similiar questions, but couldn't find any. Thank you for your help....

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.
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.
I have problem with the objects generated from Google Sceneform Tools (Beta) v1.13.0 in Android Studio.
I downloaded the object (.obj file) from poly and imported to Blender to change the dimensions. After that exported again as .obj file.
When I use it to generate .sfb file in Android Studio with Sceneform tools, the .sfb object that is generated is only black.
Left is object (.obj and .mtl) imported in Blender, and right is generated .sfb file in AndroidStudio.
Thanks in advance.
EDIT: I have checked this link, but in my case .obj file starts with these lines:...

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:

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!"
I am bit confused how to tilt an image downwards with the help of TransformableNode in google ARCore Sceneform API. I am using google Sceneform example. I am successfully able to place contents in Screen.
However, I want to tilt the facebook icon downwards like earth, which is in the table. I have tried using Node and TransformableNode as stated here, but failed to do so. Can anyone tell me how to do so? Here what I have tried so far....
ANSWERAnswered 2018-Dec-14 at 17:08
Similar to set position
cornerNode.setLocalPosition(localPosition); you can set rotation
cornerNode.setLocalRotation(new Quaternion(90f, 0f, 0f, -90f));

Download sceneform-android-sdk-1.16.0.zip from the Sceneform SDK [releases](https://github.com/google-ar/sceneform-android-sdk/releases/tag/v1.16.0) page.
Extract the sceneformsrc and sceneformux directories into your project’s top-level directory. The resulting directory structure should be similar to the following:
Modify your project’s settings.gradle to include the Sceneform projects:
Finally, add a reference to the Sceneform SDK to your app’s build.gradle:
