hololens

问题 I am about to make a Hololens software that uses some wireless connection to interact with an Android mobile phone. Do you know does Hololens support Wifi Direct? If Hololens does not support Wifi Direct, can you tell what connection technologies can be alternatively used? 回答1: At this point HoloLens doesn't support WifiDirect. Soon HoloLens updated version is going to be released and hopefully that version will have this(not yet officially confirmed). However for now you can use BLE or use

问题 I have two different Unity projects, one is a HoloLens application and the other is the desktop application. My goal is to manipulate an object in the HoloLens application through the desktop application. At the moment I have Unet working when the HoloLens is the host and the desktop acting as the client.

问题 I'm trying to capture an etl trace on the HoloLens with my own events, and some generic networking events. Using WPR on my PC, I can choose Networking I/O activity , which will show events like Microsoft-Windows-TCPIP when I analyze in WPA. I can't figure out how to see these events on a HoloLens, or successfully put them in my wprp file. I've tried the following with no success, even on Windows. My own events work fine. <EventProvider Id="Microsoft.Windows.TCPIP" Name="2F07E2EE-15DB-40F1

问题 I have freshly installed Unity 2018.3.10 with Visual Studio 2017 (15.9.10).

问题 I'm trying to make it possible to drag an object. This object can only rotate so much. (Similair to a door). Here is the code abit edited that rotates an object which works. I have 2 vectors for maxrotation and minrotation. This code will be called whenever the user is dragging the interactible object. (like update but only when dragged) if (GestureManager.Instance.IsNavigating && HandsManager.Instance.FocusedGameObject == gameObject) { //speed and navigiation of rotation float rotationFactor

问题 I am trying to capture a video of a XAML grid in UWP app using c#. My approach. 1.Use RenderTargetBitmap to take a screenshot using renderTargetBitmap.RenderAsync 2.Convert the data to byte array. 3.Create an image file with the bytes and save it on disk using BitmapEncoder 4.Create a MediaClip from that image using MediaClip.CreateFromImageFileAsync 5.Add the clips to a MediaComposition composition.Clips.Add(clip) 6.Save as a video using composition.RenderToFileAsync(video); Now this

问题 Objective: I have a pre-scanned spatial map of a room. (Carried out through an onboarding process.) We take that map and add holographic locations/markers/digital twins to it in Unity, at pre-defined static locations. E.g wallspace, fittings, etc. The app is then launched and contains all the holographic data in the correct location, irrespective of the users physical start location. In short, I want an app to start, with pre-defined holograms at set locations in the real world, irrespective
