sceneform

I understand that 3D animations such as walking are not yet supported in ARCore, but how can I animate the rotation of a Node? I know I can set LocalRotation or WorldRotation but how do I make this animated continuously in a smooth fashion? The easiest way is to use the Android Property Animation . An example of doing this is in the Sceneform sample "Solar System". Take a look at RotatingNode . This rotates the node around its axis. First, it creates an ObjectAnimator that uses LinearInterpolation to set the rotation between 4 points around a circle. private static ObjectAnimator

I'd like to place a north facing arrow into an ARCore world using sceneform. I am trying to understand the correct system of transformations to go from the phone's compass to sceneform's quaternions. This was the code I used to solve the problem: //Get the phone's pose in ARCore Pose deviceOrientedPose = frame.getCamera().getDisplayOrientedPose().compose( Pose.makeInterpolated( Pose.IDENTITY, Pose.makeRotation(0, 0, (float)Math.sqrt(0.5f), (float)Math.sqrt(0.5f)), dhelper.getRotation())); float[] devquat = deviceOrientedPose.getRotationQuaternion(); //Get the phone's heading in relation to the

I'm working on Android AR project using ARCore and Sceneform. I need to place the objects from 30 meters to 200 meters far from user's camera and faced with the frustum culling issue in ArCore, described HERE . I'm trying to set projection matrix to increase the far parameter using this method public void getProjectionMatrix (float[] dest, int offset, float near, float far); But I can't find possibility to set the rendering projection matrix. Here is my code: arFragment.arSceneView.apply { scene.addOnUpdateListener { // Some code to return from this callback if arFrame is not initialised yet

I have successfully made a line between two vectors in the AR Scene. My code: private void addLineBetweenPoints(Scene scene, Vector3 from, Vector3 to) { // prepare an anchor position Quaternion camQ = scene.getCamera().getWorldRotation(); float[] f1 = new float[]{to.x, to.y, to.z}; float[] f2 = new float[]{camQ.x, camQ.y, camQ.z, camQ.w}; Pose anchorPose = new Pose(f1, f2); // make an ARCore Anchor Anchor anchor = mCallback.getSession().createAnchor(anchorPose); // Node that is automatically positioned in world space based on the ARCore Anchor. AnchorNode anchorNode = new AnchorNode(anchor);
