3. X IMMERSIVE COMPUTING
4. Real World Computer Generated Augmented Reality Reality Virtual Reality
9. ARCore Augmented reality at Android scale
11. ARCore | Fundamentals Motion Tracking Environment Understanding Light Estimation
12. Motion Tracking
13. Environment Understanding
14. Light Estimation
15. Developer Environments
16. Prepare your device adb install -r -d arcore-preview.apk
18. Prepare yourself You will need a basic understanding of Android development with OpenGL
19. API Classes Config Session Frame Plane Pose Anchor
20. Config config = Config.createDefaultConfig()
21. Session session = Session(this) //Activity session.isSupported(config) session.pause() session.resume(config) // onSurfaceCreated session.setCameraTextureName(backgroundRenderer.textureId) // onDrawFrame val frame = session.update()
22. Frame frame.getViewMatrix(viewMatrix, 0) frame.lightEstimate.pixelIntensity frame.hitTest(tap)
23. Plane plane.trackingState == Plane.TrackingState.TRACKING plane.type == Plane.Type.HORIZONTAL_UPWARD_FACING plane.centerPose plane.planePolygon
24. Pose /** * This class tracks the attachment of object's Anchor to a Plane. It will construct a pose * that will stay on the plane (in Y direction), while still properly tracking the XZ changes * from the anchor updates. */ val pose = anchor.pose pose.getTranslation(poseTranslation, 0) pose.getRotationQuaternion(poseRotation, 0) poseTranslation[1] = plane.centerPose.ty() return Pose(poseTranslation, poseRotation)
25. Anchor val anchor = session.addAnchor(plane.centerPose) androidAttachments.add(PlaneAttachment(plane, anchor))
26. DEMO
27. Take-aways OpenGL is really required It is still a Developer Preview
28. Matt Miesnieks - https://medium.com/super-ventures-blog/how-is-arcore-better-than- The thing developers should be focussing on is that building AR Apps that people care about is really challenging. It will be far less effort to learn how to build on ARKit or ARCore than the effort to learn what to build.
29. Resources ARCore https://developers.google.com/ar Experiments https://experiments.withgoogle.com/ar How is ARCore better than ARKit? In some ways, but not others https://medium.com/super-ventures-blog/how-is-arcore-better-than- arkit-5223e6b3e79d Introducing ARCore: Augmented Reality at Android Scale (GDD Europe '17) https://www.youtube.com/watch?v=rFbcOGuDMPk Getting Started with ARCore with Kotlin https://www.raywenderlich.com/170520/getting-started-arcore-kotlin
