A physics simulation may need to be updated 120 times per second in order to ramain stalbe. A character`s artificial intelligence system may nedd to think at least once every second to prevent the apearance of stupidity. The audio library may need to be called at least once every 1/60 second in order to keep the audio buffers filled and prevent audible glithes.</div><div><br></div><div><br></div><div>It`s safe to say that the more general-purpose a game engine or middleware component is, the less optimal it is for running a particular game on a particular platform.</div><div>&nbsp;&nbsp;This phenomenon occurs because designing any efficient piece of software invariably entails marking trade-offs,and those trade-offs are based on assumptions about how the software will be used and/or about the target hardware on which it will run .For example ,a rendering engine that was designed to handle intimate indoor environments probabily won`t be very good at rendering vast outdoor environments . The indoor engine might use a BSP tree on portal system to ensure no geometry is drawn that is being occlued by walls or objects that are closer to the camera. The outdoor egine,on the other hand, might use a less-exact occlusion mechanism,or none at all,but it probabily makes aggressive use of level-of-detail(LOD) techniques to ensure that distant objects are rendered with a minimum number of triangles,while using high resolution triangle meshes for geometry that is close to the camera.</div><div><br></div><div><br></div><div>&nbsp;&nbsp; The rendering technology employed by first-person shooters is almost always highly optimized and carefully tuned to the particular type of enviroment being rendered.&nbsp;</div><div><br></div><div><br></div><div><br></div><div>STLport &nbsp;This is a protable ,optimized inplementation of STL</div><div>Boost &nbsp;Boost is a powerful data structures and algorithms library,designed in the style of STL.(The online documentation for Boost is also a great place to learn a great deal about comptuter science)</div><div><br></div><div><br></div><div><br></div><div><br></div><div>Collision detection and rigid body dynamics are provided by the following well-known SDKs,</div><div><br></div><div>Havok is a popular industrial-strength physics and collision engine.</div><div><br></div><div>PhysX is another popular industrial-strength physics and collision engine,available for free download from DVIDIA.</div><div><br></div><div>Open Dyanmics Engine(ODE) is a well-known open source physics/collision package.</div><div><br></div><div><br></div><div>&nbsp;Every game engine,and really every large,complex C++ software application,requires a grab bag of useful software utilities,</div><div>{</div><div>Module Start-Up and Shut-Down</div><div>Assertions</div><div>Unit Testing</div><div>Memory Allocation</div><div>Math Library</div><div>Strings and Hashed string IDs</div><div>Debug printing and logging</div><div>Localization Services</div><div>Parasors(CSV, XML etc)</div><div>Profiling/Stats Gathering</div><div>Engine Config &nbsp;(INI files etc)</div><div>Random Number Generator</div><div>Curves &amp; Surfaces Library</div><div>RTTI/Reflection &amp; Serialization</div><div>Object Handles/Unique Ids</div><div>Asyncthronous FIle/IO</div><div>Memory Control</div><div>}</div><div><br></div><div>Page 24 &nbsp;</div><div><br></div><div><br></div><div><br></div><div>�q�个周，��g��很�؜��q��说。。什么都不相�q�阿。。。而且各个斚w��的进度都没有��h��。。。主要旋律还是在搞机器学习的大作业，此外整了一个Ununtu的系�l�。。然后这个周�Q�发现Linux是如此的优美。。看来以后与此�ؓ伍了。。恩�Q�挺好的。。然后，要准备下周的最优化���法的考试。。前几天有些���矛盾。。慢慢改正了把。。然后开始新的工作了�Q�！</div><div><br></div><div>此外�Q�这个周SRM�l�于变色了。。。恩�Q�朝自己期望的方向又�q�出了一步！�Q�自��p��不断努力呀�Q�！�Q?/div><div><br></div><div>&nbsp;&nbsp;�q�个周之后，下周�Q�考试�Q�然后算法作�? 请qiqi Sarah吃饭�{�等一大堆的事情。�?/div><div>然后�l�箋我的Linux�Q�让生活变得习惯而充实！�Q�调研相兛_��作和Summer的图形学作业�Q?/div><div>然后HanMM被调整系��C��。。直接乘�?.75 �Q�或许这是一件好事！感觉貌似她实在是一个不值得深度交往的�h。。就是如此。。努力进行自��q��工作�Q�！</div><div><br></div><div>然后下了几本游戏的书�Q�有��Z��看以下，前面是自��q��《Game Engine Architecture 》的时候做的笔记。。�?/div>

<p>&nbsp; 1 今天我作报告。。真是囧啊。�?/p> <p>&nbsp; Summer把我问的体无完肤。。summer揪住了那个Dijkstra BFS 和A*的区别狂问。。。。还好自己对�q�个是相当清楚。。最后summer�l�于被一个电话请了出厅R���?我也���放松了一下。。不�q�，反思一下，�q�次需要有以下几个问题引�v注意</p> <p>&nbsp; 1�Q�以后做Presentation�Q�一定要用黑白颜色的。不要加入动画，朴素���最好！�Q�原因是计算所的破投媄仪根本显�C�Z�������的色了。。崩溃。�?/p> <p>&nbsp; 2 �Q�对于自��q���I�的问题一定要有一个清楚的把握。上周日开会，summer����ȝ��道。。做研究要清�?个问题。�? 首先问题是什么。�? 你的strategy�Q�创新点在哪里。�? evaluation问题。��M��设计实验来说明你的idea是creative�Q�而且比别人的更加excellent。你的研�I�在整个研究的领域中处于一个什么样的地位！�q�个是一个关键问题。�?/p> <p>&nbsp; 3�Q�对自己研究的东西，多问几个��Z��么。。很佩服summer的直觉，他��L��能用几个问题�Q�把一个研�I�的炚w��临的问题问的很透彻�Q�针针见血。。。有时候需要从一个旁观者的角度来审视自己做的东�ѝ��。。看看一个旁观者的思�\是怎么��h��理解你的东西。�?/p> <p>&nbsp;</p> <p>2 上午自己做完报告之后�Q�毛老师��׃��上�v回来了。。然后问了我几个问题。。之后是斚w��做报告。。搞一个三角剖分问题。。貌似现在世界上对三角剖分问题研�I�成熟的�Ҏ��有很多。。。而我只对Von图有一个大概的了解。。或许有旉���也需要对�q�些斚w��有一个储备吧。�?/p> <p>&nbsp;</p> <p> 3 下午�Q�就开始调研我的那个gait analysis ,在前面的文���中也提到了gait Analysis有两�U�方法。。这个我之前�q�真是不清楚。。看了n���文献，大概有一个了解。。下面是从这当中�{�选出我需要的部分。。好像看��C��个用加速度一起做的一个方法，��d��有四�U�方法，不过作者说他的数据不够多。。所以没有做�Ҏ��试验。。这个我们可以��I补他的缺��P��我还需要调研一下作者是否有相关的后�l�工作。�?</p> <p>&nbsp; 此外的Gait Analysis的另一�U�是非clinic的方法，���是从脚步中识别��Z�h。基于的都是image的方法，所以说采用的是各种降维�Ҏ���Q�从�U�性的PCA做到�?非线性的ISOMap的方法。。貌��D��个ISOMAp的方法是斯坦���的一个大�?4�q�发明的�Q�这个不是很清楚。。不�q�貌似都非常有意思。�?/p> <p>&nbsp;</p> <p> 4 装上�?Windows writer。。然后那个过零检���的�Ҏ��也做了一些调研。明天写��Z��个技术报告来吧。�?/p> <p>&nbsp;</p> <p>明日计划�Q?/p> <p>&nbsp; 1 �?zero Crossing�Ҏ��的技术报告。。需要系�l�的��M��下文献，把最初是的那个运动检���方面的那个�q�零������文献重诅R���?/p> <p>&nbsp; 2 �l�箋调研�Q�争取找出几个成熟的�Ҏ��来，如果不行�Q�向summer要一���文献，他说有一个翻跟斗的这样子的一个。。不清楚那个是什么文献。。都没找到。�?nbsp; </p> <p>&nbsp; 3 �l�箋看那本书《The Productive Programmer�?不过看了几章�Q�发现有很多都是trick�Q�就是一些程序员自我感觉良好。。其实没那么大的差别�Q�不�q�还是很有收��L��。。�?/p> <p>&nbsp; 4 看一下最大流的那个资料，今天�pȝ��的整理了一下。�?/p> <p>&nbsp; 5 如果有机会实现Ckaren Liu的那个方法也行。。毕竟那个文章还没读完。�?/p><img src ="http://www.shnenglu.com/sosi/aggbug/124479.html" width = "1" height = "1" /><br><br><div align=right><a style="text-decoration:none;" href="http://www.shnenglu.com/sosi/" target="_blank">Sosi</a> 2010-08-23 22:59 <a href="http://www.shnenglu.com/sosi/archive/2010/08/23/124479.html#Feedback" target="_blank" style="text-decoration:none;">发表评论</a></div>]]></description></item><item><title>20100822</title><link>http://www.shnenglu.com/sosi/archive/2010/08/22/124325.html</link><dc:creator>Sosi</dc:creator><author>Sosi</author><pubDate>Sun, 22 Aug 2010 14:46:00 GMT</pubDate><guid>http://www.shnenglu.com/sosi/archive/2010/08/22/124325.html</guid><wfw:comment>http://www.shnenglu.com/sosi/comments/124325.html</wfw:comment><comments>http://www.shnenglu.com/sosi/archive/2010/08/22/124325.html#Feedback</comments><slash:comments>0</slash:comments><wfw:commentRss>http://www.shnenglu.com/sosi/comments/commentRss/124325.html</wfw:commentRss><trackback:ping>http://www.shnenglu.com/sosi/services/trackbacks/124325.html</trackback:ping><description><![CDATA[
