when the sub-views are added to or removed from the hierarchy, their associated layers also correspond to the same actions in the hierarchical tree. In addition to the view level and the layer tree, there are rendering trees and render trees, and here are some UIView features that are not exposed Calayer:(Shadow, fillet, colored border, 3D transform, non-rectangular range, transparent matte, multilevel non-linear animation)Second, matrix transformationFirst, we look at the matrix structure in

1 OpenGL basics 1.1 What is OpenGL OpenGL is called Open graphics language. It refers to open graphical program interfaces. It is a cross-platform standard used for 3D rendering and 3D addition. In other words, OpenGL is a 3D API, it is an important communication bridge between 3D accelerator card hardware and 3D graphics applications. Its main goal is to realize a realistic 3D world by calling various functions provided by it. In this 3D world, objects are a collection of points, lines, and sur

Some users often ask about high-performance I/O Requirements mdash; if they can use Linux systems instead of AIX or Solaris operating systems. But no one has ever asked Windows or NTFS Some users often ask about high-performance I/O-if they can use Linux systems instead of AIX or Solaris operating systems. However, no one has ever asked about high-performance I/O (high IOPS or high-streaming I/O) in Windows or NTFS, because this is impossible. Windows and NTFS file systems have not changed much

I. Introduction and features of XFS was initially developed by SiliconGraphics, Inc. In early 1990s. At that time, SGI found that their existing File System (EFS) was quickly becoming unable to adapt to the fierce Computing Competition at that time. To solve this problem, SGI decided to design a brand new high-performance 64-bit file system, instead of trying to adjust some defects of EFS in the innate desi

-security systems and connect to IRQ ); In a multi-core system, interruptions are allocated to different processors; Set the level trigger or edge trigger mode (not equal to the peripheral trigger mode ); Virtualization extension; The arm cpu has only two external connections, one is IRQ and the other is FIQ. The corresponding processing modes are generally IRQ and FIQ respectively) processing mode. Therefore, at last, the GIC needs to integrate the interrupted sink into two lines to connect to

1. STL Basic IntroductionThe C + + STL (Standard Template Library) is a set of powerful C + + template classes, collectively known as a series of software developed by HP Labs. The purpose of the STL is to standardize the components so that they do not have to be re-developed so that the latter can use the ready-made components, and the open source components are a bit the same. There are many versions of STL, including HP STL, PJ STL, SGI STL, etc.,

I am often asked by potential customers how they can meet high I/O requirements if they can use Linux instead of AIX or Solaris. No one has ever asked me about high performance I/O on Windows or NTFS-high IOPS (input/output per second) or high I/O Stream, because this is impossible. Since its release 10 years ago, Windows and NTFS file systems have not changed much. Given

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. XfS file system is an advanced Log File System developed by SGI. XFS is highly scalable and robust. Fortunately, SGI transplanted it to the Lin ux system. In linux. The lates
