arcore

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);

I'm studying the ARCore References , Develop , make the course from Coursera , and read, understood and learn from the Samples . But I still missing some definition with some real use examples. What is a session? Every time that I need a ARCore use I need a session? Session always has a camera connect so I can see and draw/renderer my 3D models in the screen? Can I do this without a Session? Camera has a getPose and Frame has a GetPose, what are the diferences between they? I thought about make this questions split but somehow I know that they are all connected. Sessions, CameraAr, Frame and

I have been looking on the code for ARCore Unity for a while and I want to do one simple task that is, to have a toggle button so user can place an object in the scene while knowing where to place it while the tracked planes are visible and once the user places the object, he is given the option of just visually disabling the tracked planes so it looks more realistic. I was able to do this in Android Studio by doing something like this in the main HelloArActivity.java: if (planeToggle) { mPlaneRenderer.drawPlanes(mSession.getAllPlanes(), frame.getPose(), projmtx); } this was really simple. I

Is there a way to check if I touched the object on the screen ? As I understand the HitResult class allows me to check if I touched the recognized and maped surface. But I want to check this I touched the object that is set on that surface. ARCore doesn't really have a concept of an object, so we can't directly provide that. I suggest looking at ray-sphere tests for a starting point. However, I can help with getting the ray itself (to be added to HelloArActivity ): /** * Returns a world coordinate frame ray for a screen point. The ray is * defined using a 6-element float array containing the

I don't know if I'm allowed to ask this question but I really can't figure out how to use ARCore on Android Emulated Device. According to the official guide I'm supposed to use API 8.1 on pixel/pixel 2 device in order to run any app which uses ARCore. Sadly those emulator don't come with the support for Play Store, and without Play Store I can't Instal ARCore on the device. The device images that come with built in Play Store can't run ARCore instead. I'm really confused about how am I supposed to test anything for ARCore in this way. I need it to develop an app for a University program and I

I'm just playing around with AR core and want to have an object flying around the room and able to land. I'm unsure about how to add colliders to the planes that ARcore is generating based on the visuals on the room. Would this involve instantiating box colliders on the planes somehow? The ARCore SDK's trackable planes are essentially identified flat surfaces such as the ground or a tabletop. You can ask the SDK for a list of points for each trackable plane's boundary polygon (retrieved in clockwise order) and create a mesh from those points via triangulation. With the mesh ready, create a
