【正文】 rent hot spot is a soft body simulation, such as soft fabrics and simulation of the surface. The hot spot is the realtime collision detection collision detection, the study39。 I / O library provides keyboard, mouse, joystick, and other peripheral input devices.The second layer of the game engine by the physical engine, and sound renderer engine of three parts. Which provides game physics engine on the one hand between the world of objects, objects and collision detection between scenes and mechanical simulation, simulation of the movement of objects on the other hand offers。 games teaching modeCLC: Document code: A1 .IntroductionAt present, China39。s game industry is in a period of rapid development, according to International Data Corporation (IDC) report shows that in 2008 the financial crisis, China39。 renderer provides a realistic image, including graphics, textures, models and animation rendering, lighting and material handling, LOD management, etc., is one of the core game engine。s focus on discrete collision detection algorithms and collision detection based on object space. 2005 NVIDIA released its first physical with hardware acceleration puting unit PPU, will require heavy CPU or GPU for physics calculations into the PPU, in order to flexibly deal with the physical movement brings convenience, Unreal Engine3, Gamebryo, BigWorld and other game engine is to provide support for this.(3) Artificial IntelligenceArtificial intelligence is to control the game in a variety of activities the object behavior, so that they behave with mon sense logic. Application of artificial intelligence to be just right to make the game39。隨著玩家要求的提高，游戲采用的技術(shù)也越來越復雜，這給游戲產(chǎn)業(yè)界帶來了很大挑戰(zhàn)。國內(nèi)高校在游戲引擎領域的研究較為薄弱，尚處于起步探索的階段。其中實體模塊將游戲世界中的物體抽象為通用的數(shù)據(jù)結(jié)構(gòu)，提供相關的操作；動畫系統(tǒng)提供漸變動畫、蒙皮骨骼動畫效果；場景管理組織游戲物體在室外（室內(nèi)）的位置和相關的特性；特效支持提供粒子系統(tǒng)和自然模擬（如水紋、雨、煙等），使游戲畫面更為漂亮。為了提高運算的性能，除了并行計算，多線程技術(shù)之外，大量先進的算法被提出，下面分別就當前業(yè)界主要的研究熱點進行討論：（1）渲染引擎是游戲引擎中最復雜的部件，其作用是高效地顯示清晰的畫面，它的強大與否直接決定著最終的輸出質(zhì)量，往往要求在時間和處理資源有限的情況下，滿足玩家對圖形質(zhì)量的要求，著名的開源渲染引擎有OGRE、Irrlicht等，開發(fā)時通常把DirectX和OpenGL作為底層的API。物理引擎的研究集中在物理學世界建模和碰撞檢測兩個領域，其中物理學世界包括柔體和剛體兩部分，前期技術(shù)多側(cè)重于剛體的模擬，當前熱點是對柔體的模擬，例如對柔軟織物和水面的模擬。隨著更多更復雜的機器學習技術(shù)被應用到游戲中，在不久的將來很可能會出現(xiàn)專門的AI引擎，與游戲的其他部分有機地結(jié)合起來，提供更為精彩的游戲世界。游戲引擎能夠給游戲開發(fā)帶來很大的便利，越來越受到國內(nèi)產(chǎn)業(yè)界和學術(shù)界的重視。2005年NVIDIA發(fā)布了首款具有硬件加速功能的物理運算單元PPU，將需要CPU 或者GPU進行的繁重物理計算放到PPU中，為靈活處理物理運動帶來了便利，Unreal EngineGamebryo、BigWorld等多個游戲引擎已對此提供支持。除了常用的平截體揀切、遮擋揀切、材質(zhì)細節(jié)等級LOD管理、由前至后渲染等技術(shù)之外，還可以通過實時光線跟蹤、多線程渲染技術(shù)、64位高動態(tài)光照渲染HDR、動態(tài)陰影體、逐像素光照等多種技術(shù)手段綜合實現(xiàn)。其中特定類型游戲有關的組件針對特定應用提供專門的處理方法，例如 FPS、SLG、RPG 游戲組件；人工智能提供游戲運行的邏輯處理，運用智能技術(shù)提高游戲的可玩性。當前主流的 3D 游戲引擎在功能和性能上盡管各有不同，但是他們的框架和主要模塊分類上大同小異。一款優(yōu)秀的游戲引擎能夠有效地提高游戲的開發(fā)效率和健壯性，并且加快產(chǎn)品的上市時間。 first person shooter FPS need to further improve the NPC in tactical coordination, perceptual awareness level of intelligence and other capabilities, and the introduction of a richer story. Relative to other parts of the game engine, AI research efforts to be further strengthened.As more and more sophisticated machine learning techniques to be applied to the game, in the near future is likely to be the emergence of specialized AI engine, with the rest o
