Unity3D Placing a cube in front VR player and move with player position and rotation

由 感情迁移 提交于 2020-12-07 05:14:51
问题 I am developing a VR scene using Oculus Quest. I need to place a cube in front and a few units below the user eye level. The cube has to move when the user moves. E.g. if the user turns or moves the cube user secure its position by always staying in front. How can I do this? Should I take the OVRCameraRig position and rotation and apply that to the cube? But I read from StackOverflow question Unity3D Getting position of OVRCameraRig that OVRCameraRig doesn't move and needs to consider the

问题 Multiple browsers (Chrome, Firefox, Internet Explorer) give the following error when trying to open a local Unity WebGL build: It seems your browser does not support running Unity WebGL content from file:// urls. Please upload it to an http server, or try a different browser. Microsoft Edge is able to run it, but I would like to know if there are any settings that can be changed to get it to run on Chrome/Firefox/other browsers. 回答1: The correct way to run your Unity-WebGL app locally is to

基于增强现实的室内导航系统如何设计架构

关于更多机器学习、人工智能、增强现实、Unity、Unreal资源和技术干货，可以关注公众号：AIRX社区，共同学习，一起进步！ 随着技术的不断发展，在未来几年中，基于AR的室内导航应用在不同消费领域会出现大规模的增长。 室内导航与室外导航在复杂程度上有很大不同。对于户外导航，数百万人目前使用这项技术，因为它对性能要求不高;现代智能手机甚至智能手表都内置了GPS和地图。而AR室内导航技术相当复杂，它包含3个必须考虑的模块：定位，映射和渲染。 映射是唯一简单的模块(Mapping)。有了地图和坐标，就很容易制作路线。该模块易于根据给定的业务用例/需求进行升级和定制。 渲染模块管理AR内容的设计，其工作直接取决于定位的精度。我们可以轻松地以3D绘制路线，但是在将虚拟对象与现实世界进行匹配时面临一些挑战。渲染的质量和精度将取决于AR SDK等（例如ARKit、ARCore等）。 在定位方面，情况变得有些艰巨。没有准确的方法来确定用户在室内的确切位置，包括确切的楼层。确定正确的精度水平也是一个挑战。例如，十米够吗？5米呢？还是1米？ 室内定位的可用技术 用于室内定位系统的GPS：GPS是导航领域中的现有技术之一，但是，它不能提供建筑物内部的准确定位。在大型和低层建筑（例如机场）中，它相对准确；但它无法确定更详细的信息，例如楼层号，而实现此目的的唯一方法是手动进行操作

Unity软件中UGUI和NGUI的多语言开发

由 孤街醉人 提交于 2020-12-06 10:28:28
** Unity软件中UGUI和NGUI的多语言开发 ** 其中NGUI自带语言切换组件，实现动态切换多语言。 而UGUI类似NGUI,通过脚本访问固定的语言.txt。文本排列类似与表格。 UGUI两种解决方案 第一种比较笨的方法是手动的把相应文字替换掉. 第二种就是把需要切换的语言集中存放到txt文档中,通过list集合,的方法进行访问(每一个key可以对应多个value). 目标:实现中文/英文的切换. NGUI一种解决方案 NGUI自带本地化系统支持所有UILabel文本语言切换。 1.为一个Sprite添加LanguageSelection控件，会自动变成一个PopupList组件。 2. 3.为需要语言切换的UILabel添加UILocalize组件。 4. 5.Localization.txt文件设置 路径为：Assets/NGUI/Examples/Resources/ 6. 7.设置好KEY，和下面对应的文本。 8.完成，动态点击中英文切换。 目前来说NGUI自带的本地化多语言在项目中能够完好执行，能够自由切换各种写定的语言，但是在通过事件判断的多文本下却不适合。 举个例子：网络登录/密码错误/网络失败等多种状态的文本显示上就不能随机的变化，转化为其他语言。 可以看一下这个知乎的帖子。 来源： oschina 链接： https://my.oschina.net/u

HOW do Unity World Anchors work on the HoloLens?

问题 I'm currently building a HoloLens application and have a feature in-mind that requires holograms to be dynamically created, placed, and to persist between sessions. Those holograms don't need to be shared between devices. I've had a nightmare trying to find (working) implementations and documentation for Unity WorldAnchors, with Azure Spatial Anchors seeming to stomp out most traces of it. Thankfully I've gotten past that and have managed to implement WorldAnchors by using the older
