Experimental results show that the new model is efficient and flexible . direct volume rendering has been done with the volume date that came from the 2d image series . finally we displayed the truly 3d image by the computer graphic technology of eliminating the hide surface and the light 对三维重建做了初步的研究,将二维mri图像序列转化为三维体数据,应用体绘制算法实现了三维重构,并通过光照、隐藏面消除等计算机图形学算法实现真实感图形显示,从计算机屏幕上给出了形象逼真的人体脑部三维结构立体视图。
Computer results and experimental datum testify the reasonableness of mathematical model . with the computer development , especially the computer graphic ' s development , we can simulate the multi - body " movement . using the computer results as animation program ' s input data , describe the real trace of multi - bodies system in computer advanced language vc + + 利用先进的计算机技术-计算机图形学的方法,再根据计算所得的末敏弹各个刚体的运动参数作为动画软件的输入参数,在计算机中用vc + +调用opengl函数库,建立三维图形,模拟出末敏弹的运动。
In this paper , the doppler signed of cartridge velocity , that is produced by the doppler radar , is taken as the research object . the characteristics of the doppler signal of several kinds of cartridges are analyzed . the spectrum analysis method is used to measure the velocity of several kinds of cartridges , based on digital data processing technology and computer graphic technology 本文以多普勒雷达测量弹丸速度得到的多普勒信号为研究对象,分析多种弹丸速度多普勒信号频率特征,运用数字信号处理方法和计算机图形处理技术相结合的频谱分析方法测量多种弹丸的速度。
