Codemotion Roma 2018 - Alessandro Pozone, Matteo Valoriani If you think there's been a lot of talk about Augmented Reality and Virtual Reality this year, 2018 is going to blow you away. ARkit, ARCore, HoloLens, Magic Leap, Oculus and many others are working to transform our Reality with new products and services. Apple, Microsoft, Intel, Google and Facebook are approaching AR/VR from different perspectives and technologies: in this session we will try to understand how these different technologies can work together and create a shared multi device experience.

- 24. Visual Inertial Odometry (VIO) 6dof in real time : • 3D of xyz motion (translation) • 3D of pitch/yaw/roll (rotation) Pose is tracked: • via the Camera system, by matching a point in the real world to a pixel on the camera sensor each frame. • by the Inertial system (accelerometer & gyroscope — Inertial Measurement Unit or IMU) The output of both of those systems are then combined via a Kalman Filter which determines which of the two systems is providing the best estimate of your “real” position.

Lighting Estimation Estimation of light available in a scene in order to apply the correct amount of lighting to virtual objects. Hardware and Rendering Optimizations Apple A9, A10, and A11 processors.

- 42. Urho (Finnish for “hero” or “brave fighter”) was a legendary, tyrannical king among the fish. He always hunted without mercy. Sadly, he passed away on 6th November 2009. This engine was originally called Bofh3D (hinting at the covert goal of reimplementing the game BOFH: Servers under Siege in 3D) but was renamed to Urho3D in his honor. URHO3D For more of Urho’s legend, see also the music project http://www.mikseri.net/Urho/

- 46. • A Scene is the root of a game ‘world’ and is rendered into a Viewport by a Camera • A Scene contains a hierarchy of Nodes • A Node has an identifier and a translation in 3D-space • A Node may contain child Nodes • Node type include Light and Camera • Trasform applied to Node and children SCENE TREE
- 47. • A Node can contain Components which add behaviour • StaticModel – allows the the node to be rendered • RigidBody – allows the node to participate in physics • SoundSource – allows the node to emit audio • Light – allows the node to emit light • Actions can also be attached to a Node, allowing declarative specification of behaviour SCENE TREE (2)
