Rendering Terrain Dynamically with Argument Buffers : Understanding why the particle buffer is not overwritten by the GPU inflight

由 六月ゝ 毕业季﹏ 提交于 2021-01-29 22:18:31
问题 I am looking through an Apple demo project that is associated with the 2017 WWDC video entitled "Introducing Metal 2" where the developers demonstrate the use of argument buffers. The project is linked here on the page titled "Rendering Terrain Dynamically with Argument Buffers" on the Apple developer website. Here, they synchronize resource writes by the CPU to prevent race conditions with a dispatch_semaphore_t , signaling it when the command buffer finishes executing on the GPU and waiting

3 月，跳不动了？>>> 苹果正式宣布第 29 届年度全球开发者大会（WWDC 2018）将于美国当地时间 6 月 4 日星期一（北京时间 6 月 5 日凌晨一点）拉开帷幕，大会将持续到 6 月 8 日星期五。和 2017 年一样，此次会议的地点依旧是加州圣何塞 McEnery 会议中心。 作为业界的“风向标”，苹果公司通常会利用 WWDC 向开发者推出可在其操作系统上运行的新工具，包括新版 iOS 操作系统，以及 Mac、Apple TV 和 Apple Watch 软件的各个新版本等。去年苹果公司就在 WWDC 上推出了 iOS 11 和 macOS High Sierra 操作系统，以及 HomePod、iMac Pro、10.5 英寸 iPad Pro、watchOS 4 和 ARKit。 此次开发者大会，不出意外的话，苹果将在 WWDC 2018 上推出新的软件系统，同时硬件产品也将得到更新。目前来看，苹果很有可能会发布 iOS 12、macOS 10.13.4、tvOS 12 和 watchOS 5 等软件，硬件方面，新款 MacBook Air 以及 iPad Pro 都很有可能到来。 iOS 12 无疑会是今年的重点 毫无疑问，今年将会重点放在 iOS 的未来，特别是 iOS 12 的可靠性和性能方面。iOS 11 自推出以来一直备受诟病，更是深陷“降速门”以及多种

【编者按】2015年6月，一年一度的苹果 WWDC 大会如期而至，在大会上苹果发布了 Swift 2.0，引入了很多新的特性，以帮助开发者更快、更简单地构建应用。本篇文章作者是 Maxime defauw ，本文中 Maxime 向大家简要介绍 Swift 2.0 中值得注意的新特性。本文系 OneAPM 工程师编译整理。 一年前，苹果推出了面向 iOS 和 OS X 的全新编程语言—— Swift。当听到它发布的时候，像千千万万 iOS 开发者那样，笔者的内心激动无比。正如宣传所说的那样，作为一门快速、安全的编程语言，Swift 已经成长为最流行的编程语言之一。一年之后，苹果不负众望，在2015年的 WWDC 会议中推出了 Swift 2.0。作者有幸去了现场，所以在这里向大家介绍一下 Swift 2.0 的新特性。 「今年，我们将借助 Swift 2.0 乘风破浪。我们认为 Swift 即将成为最大的编程语言，并且成为下个二十年最不可或缺的应用和系统编程语言。任何人在任何地方都能使用 Swift 」，苹果公司软件工程副总裁 Craig Federighi 说道。 在 WWDC 大会上，苹果测量了分贝的新功能普及性。会议中两次最大的掌声，一次是苹果宣布 Xcode 7 支持 UI 测试，另一次则是 Swift 的开源。如果你错过 WWDC 的主题演讲，或者最近生活得压力山大

What is mean by Screen space in ARKit?

由 折月煮酒 提交于 2019-12-23 17:37:20
问题 When I went through the video for session 805, Creating Great AR Experiences, and they mention using screen space text when displaying text in AR. They use the example of their Measure app that works quite well. I want to achieve similar functionality. But, I am not able to figure it out. 回答1: Screen Space is the 2D pixel coordinate system of your display. It's where you normally do things like laying out UIKit widgets in screen space, etc. The alternative to Screen Space is a 3D coordinate

iOS 11 Files App: How to include files from app bundle

由 这一生的挚爱 提交于 2019-12-23 09:17:26
问题 I watched the keynote this year at WWDC and am excited about all the new feature additions being brought to iOS 11. The high importance Apple has placed on games in the App Store and the biggest upgrades in the history of iPad is very exciting. But what was most thriling to me was that iOS 11 will bring for the first time some sibilance of a file system to iOS. They call it the Files app, naturally. It seems a big step forward in the new user's getting that same windows-like experience from

iOS13 Provisional Location Permission

由 谁都会走 提交于 2019-12-13 11:22:10
问题 Since apple has deferred the "Always Allow" permission and only OS can and will ask for that permission based on its own convenience, it is hard to understand what all the scenarios are. If you see the WWDC video: https://developer.apple.com/videos/play/wwdc2019/705/ The guy clearly says at 04:14, "you ask for requestAlwaysAuthorization, apple provides you with the max option of "While In Use", but at the same time the delegate callback says, the app has "Always Allow permission"". This works
