    粒子效果演示(附代码) 利用C++所提供的一些标准容器很容易实现粒子效果. 简单的说就是,将粒子数据写在一个类里面,有一个粒子源,不停地生成粒子,然后放入一个stl::list中(push_back()方法), 然后在一个循环中遍例粒子链表,并渲染粒子,粒子的参数并不断更新,如果粒子的ALPHA值小于0,即不可见了,即代表粒子已经死亡, 即从list中删去(erase()方法), 销毁死去的粒子很重要, 如果搞忘了这一步, 你的内存很快就会被吃掉干净了. 第一个版本是用交错平面画的粒子. 第二个版本是用Point Spirit(点精灵)画的粒子, 可以看看效果上面的区别 SPACE - 暂停粒子源发射粒子 LINK中忘记去掉cg.lib cgGL.lib 了, 此程序不需要CG, 如果要编译请去掉.

  • 欢迎使用ERwin信息模型

    欢迎使用ERwin信息模型,以前如果你从未见过模型,ERwin Methods Guide将帮助你了解什么是模型,以及它适合于什么。如果你已经一些有使用数据和信息模型的经验,那么你知道它在业务需求中是很有用的。如果在设计新的信息系统或在维护和修改存在的东西,模型能帮助你。本文没有包括信息模型的许多细节。但是,到你读完它的时候,你将足够地了解它,即使你仅仅初学者,ERwin的方法也将为你工作。本文覆盖了由 ERwin支持的信息模型方法,它不包括了ERwin的详细使用,如何使用 ERwin工具请见”ERwin User s Guide”。由 ERwin支持的信息模型方法是神秘的缩写字:”IDEF1X”,IDEF1X方法由 U.S.空军开发。目前,它应用于空军、政府机构、航空工业和财政部门、大公司、大型企业。并且,信息模型在各种主要的管理严格的大公司是必需的。

  • A MATLAB GUI platform for realizing the radiation pattern of narrowband beamformer with random array

    A MATLAB GUI platform for realizing the radiation pattern of narrowband beamformer with random array geometry. User can specify the array geometry, directions of incoming signals, noise power, and the type of beamformer. Useful for gaining insight about collaborative beamforming in sensor networks and random arrays. You need both randomarray.fig and randomarray.m to work.

    Description: Microsoft?Windows?HTTP Services (WinHTTP) provides developers with a server-supported, high-level interface to the HTTP/1.1 Internet protocol. WinHTTP is designed to be used primarily in server-based scenarios by server applications that communicate with HTTP servers. WinHTTP is also designed for use in system services and HTTP-based client applications. WinHTTP is more secure and robust than WinInet. However, single-user applications that need FTP or gopher functionality, cookie persistence, caching, automatic credential dialog handling, Internet Explorer compatibility, or downlevel platform support should still consider using WinInet.

    A "code-what"? Unless you have spent some time working in the area of reverse engineering, chances are you have not heard of the term "codecave" before. If you have heard of it, you might not have read a clear definition of it or quite understand what it is or why it is useful. I have even asked seasoned assembly programmers about the term before and most of them had not heard of it. If it is new to you, do not worry, you are not the only one. It is a term that is scarcely used and is only useful in a reverse engineering context. Furthermore, is it "codecave" or "code cave"? I am not quite sure, but I will try my best to refer to it consistently as a "codecave". A space may sneak in there from time to time

    It can be argued that the current free-software movement is the most important thing happening in computing today. We are in the midst of a major shift from all software being proprietary and closely held by individual companies to a large body of software that can be freely acquired and used by anyone for any purpose. Free software now includes not only programming language compilers and linkers, but numerous utilities, graphical user interface environments, and even entire operating systems.

    This file contains board-specific information for the Motorola cpv3060 target board. Specifically, this file contains information on any BSP interface changes from previous software or hardware versions, and contains caveats that the user must be aware of before using this BSP. Additionally, the target board s reference entry (i.e., cpv3060/target.nr) provides board-specific information necessary to run VxWorks, and should be read before this BSP is used.
