Research on Parallelization of Three-dimensional Scene Based on Multi-core Processors

提高三维场景的运行速度一直以来都是程序开发人员需要面临的一大难题,随着面向主流应用的多核处理器的出现与普及,利用处理器提供的多个内核而不通过编写多线程的方法来提高程序的并行性成为了一种可能。本文介绍虚拟现实开发工具OPEngl和共享存储系统并行编程接口OPEnMP;分析OPEngl绘制三维场景的一般过程;并以纹理映射为例着重探讨在OPEngl程序中使用OPEnMP来提高程序并行性的方法。Improving the speed of three-dimensional scene has always been a major challenge which programmers need to face.With the appearance and popularization of the multi-core processor,using the cores on processor instead multi-threading methods to improve parallelism of the program has become a possibility.This article introduces the development of virtual reality tools OpenGL and parallel programming interface OpenMP which is a shared-memory systems,analyzes the general process of using OpenGL to draw up the three-dimensional scene,and takes the texture-mapping as an example to discuss how to used OpenMP in the OpenGL program to enhance the parallelism

Simulation and Training System for Substation Based on C/S Architecture

变电站运行人员的个人技能是影响电力系统安全可靠运行的重要因素之一，因此，在运行人员正式上岗之前需要对其进行技能培训。目前，国内外已经开发出了许多变电站仿真培训系统，并取得了不错的效果。 变电站地理位置分散，人员相对精简，如果经常性的抽调大批运行人员到培训中心集中进行培训，有可能影响到正常的生产秩序，为了满足变电站运行值班人员的培训需求，提高培训效率，可以对其进行网络化培训。随着Internet技术的发展，以及网络带宽的不断增大，使得网络化的变电站仿真培训成为可能。本文针对网络化需求提出了基于C/S架构的变电站仿真培训系统。 首先，本文采用面向对象的程序设计方法，对基于网络化的变电站仿真培训...The personal ability of substation operator is one of the most important factors that affect the security and reliability of electric power system. So, the substation operator should be trained before he/she starts to operate real equipment. At present, many simulation training systems for substation have been developed and effectively used. Substations are geographically dispersed and relat...学位：工学硕士院系专业：信息科学与技术学院计算机科学系_计算机系统结构学号：2302007115130
