基于虚拟现实技术的物理实验模拟

时间:2017-08-11 数学毕业论文 我要投稿

摘要
 
如今,我们已经能够在计算机中以3维的方式真实地模拟现实世界的物理实验。这意味着,我们完全不用那些笨重、昂贵的设备,就可以随时做你想做的实验。这其中的关键技术是VR。
VR(虚拟现实)是计算机应用中快速发展的1种技术。用这种技术,人们可以用3维的形状和场景描述身边的世界。它有着广泛的适应性。作为VR技术中的1种,VRML(虚拟现实模型语言)由于它的简便易学,拥有着大量的用户群。它是1种在网页上的国际化3维描述语言标准。
在这份报告中,我将展示VRML语言及用该语言编写物理力学虚拟实验的方式。下面是关于选题的更详细的说明。
所选的第1个实验是关于平抛运动。通过路径上1些点的坐标,我们可以计算出小球离开轨道时的初速度。
第2个实验是单摆。通过对测出1次全振动花费的时间,我们可以算出重力加速度的值。
最后1个实验是自由落体运动。
所有这些将用VRML实现,其中JavaScript语言控制了其大部分功能。

Abstract

Now, we can simulate the experiments of physics in 3-D mode in computer like it is in the real world. It means we can do the experiment without those heavy, expensive equipments just at any moment you want. The key technology is VR.
VR(Virtual Reality)is a fast developing technology in the application of computer. With this technology, people can describe the world around in 3-D shapes and scenery. It has very broad applicability as one of the VRs technologies. VRML (the Virtual Reality Modeling Language) has plenty of users, as it is very easy to learn. It is an international standard in 3-D description language on the World Wide Web.
In this report, I will show the language VRML and the way that I use it to build a 3-D scene in mechanics experiment of physics. Below this are the explication of the theme I chose.
The first production chosen is about horizontal projectile motion[7],from the coordinates of the points in the path,we might come to the conclusion of the original speed that the ball leaves from the track。
 The topic of the second one is single pendulum.After taking count of the time it finishes a complete vibration,we can get the value of the acceleration due to gravity.
 The last one is about the free fall motion..All above I will achieve in VRML,in which language JavaScript controls a majority of function.

Keywords:VR,VRML,physics,mechanics
