基于opengl的3D天体运动模型设计方案

基于opengl的3D天体运动模型设计方案学生： ____？？？___学号： ************指导老师： ___？？？___一、背景简介1.1设计概述本3D建模设计运用Win32程序设计的基本原理，基于OpenGL接口函数，以Microsoft Visual Studio 2008为开发工具，以C++语言为开发语言，设计了一个星空背景下的太阳—地球—月球公转自转运动模型，模拟了太阳的光照效果，并实现了可以加速和减速地球和月球的自转、公转速度，而且还可以调整视图的远近和方位，方便各方面的观察。

1.2 OpenGL的基本特点OpenGL即开放图形库（Open Graphics Library），是一个三维的计算机图形和模型库。

OpenGL作为一个性能优越的图形应用程序设计接口，适用于广泛的计算机环境。

从个人计算机到工作站和超级计算机，OpenGL都能实现高性能的三维图形功能。

OpenGL是一个与硬件图形发生器的软件接口，它包括了100多个图形操作函数，开发者可以利用这些函数来构造景物模型、进行三维图形交互软件的开发。

正如上一章所述，OpenGL是一个高性能的图形开发软件包。

OpenGL支持网络，在网络系统中用户可以在不同的图形终端上运行程序显示图形。

OpenGL作为一个与硬件独立的图形接口，它不提供与硬件密切相关的设备操作函数，同时，它也不提供描述类似于飞机、汽车、分子形状等复杂形体的图形操作函数。

用户必须从点、线、面等最基本的图形单元开始构造自己的三维模型。

当然，像OpenInventor那样更高一级的基于OpenGL的三维图形建模开发软件包将提供方便的工具。

因此OpenGL的图形操作函数十分基本、灵活。

它具有如下特点。

（1）图形质量好、性能高。

无论是三维动画、CAD，还是视觉模拟、可视化计算等，都利用了OpenGL高图形质量、高性能的特点。

这个特点使得程序开发者在广播、CAD/CAM/CAE、娱乐、医学图像和虚拟现实等领域中创造和显示出难以想象的2D和3D图形。

计算机图形学opengl动画的实现源代码

实验目的：
在VC6.0的opengl的环境下，实现固定物体的连续变化，从而使简单动画得以实现。

实验思想：
由于是简单图形的变化过程，所以问题关键在于：
1、物体的位置变化如何实现，而位置变化在opengl中体现在坐标的变化中，因而设置坐标的每一步物体的位置变化情况是该问题的关键，此关键代码如下：
wAngleX += 1.0f;
wAngleY += 10.0f;
wAngleZ += 5.0f;
2、再有就是如何使得连续的变化得以实现，这就实现了手动变化相自动变化的转变，为了实现这一问题，我们想到设置一个变化时间，使得物体在每个时间段变换一次位置，当这个时间适当小时，就实现了物体的连续变化；这就需要引进一个计时器，通过设置间隔时间实现物体的连续变化，此关键代码如下：
SetTimer(1, 150, NULL);
实验步骤：
1、初始化OpenGL。

2、设置菜单与关联函数初始化，设置视口与窗口匹配，重新设置坐标系统。

3、建立正交变换下的剪切体（即变换物体）。

4、编写变换幅度函数，设置没不变换情况。

5、编写连续变换计时器，使得在一定间隔下连续变换。

实验关键代码：
实验结果：。

2、gluSphere（quadric, 0.45f, 40, 40）函数是在原点绘制图形，经过 glTranslatef* 和 glRotatef*平移和旋转可以随意改变球体位置：
glRotatef(-90.0f, 1.0f, 0.0f, 0.0f); // 将坐标系绕 X 轴旋转-90 度 glTranslatef(1.7f, 0.0f, 0.0f); // 将坐标系右移 1.7f
8、建立一个地球公转轨道，调用函数 glTranslatef*把球体平移一定距离，使其在自
4
己的轨道上运行。同时为了使月球跟随地球，glRotatef(fEarthOrbit , 0.0f, 1.0f, 0.0f); 将坐标系绕 Y 轴旋转地球公转的角度,控制月亮跟随地球，用函数 glTranslatef*平移使月球轨道在地球周围而不与地球重叠。
5
参数代表要操作的目标，GL_PROJECTION 是对投影矩阵操作，GL_MODELVIEW 是对模型视景矩阵操作，GL_TEXTURE 是对纹理矩阵进行随后的操作。 13、glutIdleFunc(void (*func)(void))在 glutIdleFunc(void (*func)(void))回调函数中指定一个函数，如果不存在其他尚未完成的事件（例如，当事件循环处于空闲的时候），就执行这个函数。这个回调函数接受一个函数指针作为它的唯一参数。如果向它传递 NULL(0),就相当于禁用这个函数。glutMainLoop 进入 GLUT 事件处理循环。在一个 GLUT 程序中，这个例程被调用一次。一旦被调用，这个程序将永远不会返回无限循环。它将调用必要的任何已注册的回调。程序最后调用这个函数，让程序循环执行下去，使运动继续下去。
9、OpenGl 把三维坐标中的球体绘制到而为坐标屏幕,绘制的顺序是按代码的顺序来进行的。因此后绘制的物体会遮住先绘制的物体，既使后绘制的物体在先绘制的物体后面也是一样，使用深度测试可以解决这个问题。使用方法是：以 GL_DEPTH_TEST 为参数调用 glEnable 函数，启动深度测试。在必要时（通常是每次绘制画面开始时）清空深度缓冲，即： glClear(GL_DEPTH_BUFFER_BIT) ，其中 glClear(GL_COLOR_BUFFER_BIT) 与 glClear(GL_DEPTH_BUFFER_BIT) 可以合并写为 glClear(GL_COLOR_BUFFER_BIT| GL_DEPTH_BUFFER_BIT)，且后者运行速度比前者快。

地球动效代码

地球动效代码地球动效是一种通过计算机程序实现的模拟地球自转和公转运动的效果。

通过编写相应的代码，可以让地球呈现出逼真的运动轨迹和变化。

在编写地球动效代码时，我们需要使用一些数学知识和计算机图形学的基础知识。

首先，我们需要确定地球的中心点和半径，以及地球自转和公转的速度。

然后，我们可以使用三维坐标系来表示地球的位置和运动轨迹。

在代码中，我们可以使用一些常见的编程语言，如JavaScript、Python或C++来实现地球动效。

下面是一个使用JavaScript语言实现地球动效的示例代码：```javascript// 设置地球的中心点和半径var earthCenter = { x: 0, y: 0, z: 0 };var earthRadius = 100;// 设置地球的自转和公转速度var earthRotationSpeed = 0.01;var earthRevolutionSpeed = 0.005;// 创建一个函数来更新地球的位置function updateEarthPosition() {// 计算地球的自转角度var earthRotationAngle = earthRotationSpeed * Date.now(); // 计算地球的公转角度var earthRevolutionAngle = earthRevolutionSpeed * Date.now();// 计算地球在三维坐标系中的位置var earthX = earthCenter.x + earthRadius * Math.sin(earthRevolutionAngle);var earthY = earthCenter.y + earthRadius * Math.cos(earthRevolutionAngle);var earthZ = earthCenter.z;// 将地球的位置应用到对应的HTML元素上var earthElement = document.getElementById('earth');earthElement.style.transform = 'translate3d(' + earthX + 'px, ' + earthY + 'px, ' + earthZ + 'px) rotateY(' + earthRotationAngle + 'rad)';}// 创建一个动画循环来更新地球的位置function animate() {requestAnimationFrame(animate);updateEarthPosition();}// 启动动画循环animate();```在这个示例代码中，我们首先设置了地球的中心点和半径，以及自转和公转的速度。

华中科技大学计算机图形学实验报告——画直线、日地月模型

华中科技大学计算机图形学实验报告——画直线、日地月模型计算机图形学基础实验报告专业：班级：姓名：学号：日期：OpenGL简介(1)OpenGL作为一个性能优越的图形应用程序设计界面（API），它独立于硬件和窗口系统，在运行各种操作系统的各种计算机上都可用，并能在网络环境下以客户/服务器模式工作，是专业图形处理、科学计算等高端应用领域的标准图形库。

它具有以下功能。

1. 模型绘制2. 模型观察在建立了三维景物模型后，就需要用OpenGL描述如何观察所建立的三维模型。

3. 颜色模式的指定OpenGL应用了一些专门的函数来指定三维模型的颜色。

4. 光照应用用OpenGL绘制的三维模型必须加上光照才能更加与客观物体相似。

5. 图象效果增强OpenGL提供了一系列的增强三维景观的图象效果的函数，这些函数通过反走样、混合和雾化来增强图象的效果。

6. 位图和图象处理OpenGL还提供了专门对位图和图象进行操作的函数。

7. 纹理映射8. 实时动画9. 交互技术应用软件OpenGL窗口系统操作系统图形硬件图1.1 OpenGL图形处理系统的层次结构(2)OpenGL的操作步骤在OpenGL中进行的图形操作直至在计算机屏幕上渲染绘制出三维图形景观的基本步骤如下：1. 根据基本图形单元建立景物模型，得到景物模型的数学描述（OpenGL 中把点、线、多边形、图像和位图都作为基本图形单元）；2. 把景物模型放在三维空间中的合适的位置，并且设置视点(Viewpoint)以观察所感兴趣的景观；3. 计算模型中所有物体的色彩，同时确定光照条件、纹理粘贴方式等；4. 把景物模型的数学描述及其色彩信息转换至计算机屏幕上的像素，这个过程也就是光栅化(rasterization)。

在这些步骤的执行过程中，OpenGL可能执行其他的一些操作，例如自动消隐处理等。

另外，景物光栅化之后被送入帧缓冲器之前还可以根据需要对象素数据进行操作。

(3)OpenGL的组成OpenGL不是一种编程语言，而是一种API（应用程序编程接口），它实际上是一种图形与硬件的接口，包括了多个图形函数。

1.太阳和月亮的简介
太阳和月亮是我们宇宙中最重要的天体之一。

太阳是太阳系中的中心，它是地球上生命的源泉，为地球提供了光和热。

月亮是地球的卫星，它对地球的潮汐和气候有着重要的影响。

2.太阳和月亮的源代码
太阳的源代码是太阳的核心，它由氢原子核聚变成氦原子核，释放出巨大的能量。

这个过程是通过核聚变反应实现的，它的数学表达式是：4 个氢原子核（质子）聚变成一个氦原子核，同时释放出 2 个正电子和中微子。

月亮的源代码是它的岩石层，它是由撞击地球的小行星和彗星形成的。

月亮的岩石层由各种不同的矿物质组成，包括橄榄石、辉石和斜长石等。

3.太阳和月亮源代码的启示
太阳和月亮的源代码告诉我们，宇宙中的万物都是有其内在规律的。

太阳的源代码揭示了核聚变的原理，这个原理被广泛应用于核能发电和核武器等领域。

月亮的源代码揭示了地球形成的过程，帮助我们更好地理解了地球的演化历程。

同时，太阳和月亮的源代码也启示我们，保护环境和资源是至关重要的。

太阳和月亮是我们宇宙中最重要的天体之一，它们的存在和演化对地
球的生命和生态系统产生了深远的影响。

opengl实现太阳系天体运动

Opengl实现太阳系天体运动本文主要讲OpenGL中的几何变换。

我们生活在一个三维的世界——如果要观察一个物体，我们可以：1、从不同的位置去观察它。

（视点变换/视图变换，gluLookAt）2、移动或者旋转它，当然了，如果它只是计算机里面的物体，我们还可以放大或缩小它。

（模型变换）3、如果把物体画下来，我们可以选择：是否需要一种“近大远小”的透视效果。

另外，我们可能只希望看到物体的一部分，而不是全部（剪裁）。

（投影变换）4、我们可能希望把整个看到的图形画下来，但它只占据纸张的一部分，而不是全部。

（视口变换）这些，都可以在OpenGL中实现。

1、模型变换和视图变换从“相对移动”的观点来看，改变观察点的位置与方向和改变物体本身的位置与方向具有等效性。

在OpenGL中，实现这两种功能甚至使用的是同样的函数。

由于模型和视图的变换都通过矩阵运算来实现，在进行变换前，应先设置当前操作的矩阵为“模型视图矩阵”。

设置的方法是以GL_MODELVIEW为参数调用glMatrixMode函数，像这样：glMatrixMode(GL_MODELVIEW);通常，我们需要在进行变换前把当前矩阵设置为单位矩阵。

这也只需要一行代码：glLoadIdentity();然后，就可以进行模型变换和视图变换了。

进行模型和视图变换，主要涉及到三个函数：glTranslate*，把当前矩阵和一个表示移动物体的矩阵相乘。

三个参数分别表示了在三个坐标上的位移值。

glRotate*，把当前矩阵和一个表示旋转物体的矩阵相乘。

物体将绕着(0,0,0)到(x,y,z)的直线以逆时针旋转，参数angle表示旋转的角度。

glScale*，把当前矩阵和一个表示缩放物体的矩阵相乘。

x,y,z分别表示在该方向上的缩放比例。

注意我都是说“与XX相乘”，而不是直接说“这个函数就是旋转”或者“这个函数就是移动”，这是有原因的，马上就会讲到。

假设当前矩阵为单位矩阵，然后先乘以一个表示旋转的矩阵R，再乘以一个表示移动的矩阵T，最后得到的矩阵再乘上每一个顶点的坐标矩阵v。
