AR and VR learning how to get started-explore the chapter

1.VR/AR/MR, respectively, representing Virtual Reality (VR)， augmented Reality (augmented reality)And Mixed Reality (mixed reality)。 The three can be roughly divided into one area, but The VR world will completely replace the real world when it is presented, and the user cannot see the real world at this time .； AR is an overlay of information on a real-world basis, and your actions in the real world will not be affected .； Mr is the real world and the virtual world together, what you see in the real world will be affected by the virtual world, so you can not distinguish between what you see is a real object or a virtual object。 VR = Binocular rendering + hardware display device, generally developed with Oculus, Facebook announced the acquisition of Oculus at $2 billion in July 2014, so you know, for the moment, VR is a fire, but there's no such thing as a bright one. 2.AR is a three-dimensional environmental recognition, belongs to the category of machine vision. The typical AR scenario is to see virtual objects in the real world by means of display devices. It is divided into three parts, camera is responsible for capturing real-time scene scenes, background program responsible for environment identification and camera positioning, the display device renders the virtual and displayed images in combination with rendering. So AR = Camera + visual algorithm + display device(from the Know). The most widely used vuforia+unity development process is the Metaio (acquired by Apple) virtual reality: Sony (PSVR), HTC (Vive), Fackbook (Oculus) Augmented Reality: Microsoft (Hololens). 3. What is AR, real ar should be the virtual world and the real world synchronous rendering, to achieve virtual and realistic interaction, augmented reality of the outbreak will take some time. 4.Vuforia main product is Vuforia platform, divided into trial version, classic version, Vuforia cloud Three versions, this company also provides AR engine, was previously acquired by Qualcomm, in October 2015, Qualcomm sold it to PTC for $65 million. VUFORIAA currently has 175,000 registered developers and more than 20,000 apps. Together with Metaio, Vuforia is the world's largest two AR development engine, both of which have been acquired. reference:1.https://www.zhihu.com/question/40099190
