opengl mvp

MVP变换是图形学的基础，也是理解的难点。理论解释看了很多遍，每次都似懂非懂结果下次用到又忘了……这次在学习OpenGL的过程中看到了官方案例，能很直观地帮助我们理解MVP矩阵。LearnOpenGL真的是学习OpenGL的保姆级教材，强推！！！

本文用到的案例来源于《LearnOpenGL》坐标系统一章中所给出的最后一个案例

案例来源：坐标系统 - LearnOpenGL

 案例源代码及配置方式详见本文末尾。

MVP变换

 在图形渲染管线中，MVP变换发生在顶点着色器(vertex shader)中。在OpenGL中，对应于顶点着色器代码文件中的这样一段内容：

  1. #version 330 core
  2. layout (location = 0) in vec3 aPos;
  3. ...
  4. uniform mat4 model;
  5. uniform mat4 view;
  6. uniform mat4 projection;
  7.  
  8. void main()
  9. {
  10.     // Model-View-Projection变换
  11.     gl_Position = projection * view * model * vec4(aPos, 1.0);
  12.     ...
  13. }

其中，aPos是一个从外部输入的三维坐标，它被齐次化为(x,y,z,1)的形式。model、view、projection是三个4x4的矩阵，其值也来自于外部输入。顶点着色器最终将经过MVP变换的顶点坐标赋值给OpenGL中预定义的gl_Position，即完成了MVP变换。

我们想要了解的是aPos、model、view、projection分别代表什么，接下来将结合案例代码讲解。

aPos数组：物体的顶点坐标

在案例的main.cpp中可以找到一个名叫vertices的float数组，这就是顶点着色器中aPos所对应的值。

  1.     //每行只看前三个数即可，后两个数对应纹理坐标，与MVP变换无关
  2.     float vertices[] = {
  3.         -0.5f, -0.5f, -0.5f,  0.0f, 0.0f,
  4.          0.5f, -0.5f, -0.5f,  1.0f, 0.0f,
  5.          0.5f,  0.5f, -0.5f,  1.0f, 1.0f,
  6.          0.5f,  0.5f, -0.5f,  1.0f, 1.0f,
  7.         -0.5f,  0.5f, -0.5f,  0.0f, 1.0f,
  8.         -0.5f, -0.5f, -0.5f,  0.0f, 0.0f,
  9.  
  10.         -0.5f, -0.5f,  0.5f,  0.0f, 0.0f,
  11.          0.5f, -0.5f,  0.5f,  1.0f, 0.0f,
  12.          0.5f,  0.5f,  0.5f,  1.0f, 1.0f,
  13.          0.5f,  0.5f,  0.5f,  1.0f, 1.0f,
  14.         -0.5f,  0.5f,  0.5f,  0.0f, 1.0f,
  15.         -0.5f, -0.5f,  0.5f,  0.0f, 0.0f,
  16.  
  17.         -0.5f,  0.5f,  0.5f,  1.0f, 0.0f,
  18.         -0.5f,  0.5f, -0.5f,  1.0f, 1.0f,
  19.         -0.5f, -0.5f, -0.5f,  0.0f, 1.0f,
  20.         -0.5f, -0.5f, -0.5f,  0.0f, 1.0f,
  21.         -0.5f, -0.5f,  0.5f,  0.0f, 0.0f,
  22.         -0.5f,  0.5f,  0.5f,  1.0f, 0.0f,
  23.  
  24.          0.5f,  0.5f,  0.5f,  1.0f, 0.0f,
  25.          0.5f,  0.5f, -0.5f,  1.0f, 1.0f,
  26.          0.5f, -0.5f, -0.5f,  0.0f, 1.0f,
  27.          0.5f, -0.5f, -0.5f,  0.0f, 1.0f,
  28.          0.5f, -0.5f,  0.5f,  0.0f, 0.0f,
  29.          0.5f,  0.5f,  0.5f,  1.0f, 0.0f,
  30.  
  31.         -0.5f, -0.5f, -0.5f,  0.0f, 1.0f,
  32.          0.5f, -0.5f, -0.5f,  1.0f, 1.0f,
  33.          0.5f, -0.5f,  0.5f,  1.0f, 0.0f,
  34.          0.5f, -0.5f,  0.5f,  1.0f, 0.0f,
  35.         -0.5f, -0.5f,  0.5f,  0.0f, 0.0f,
  36.         -0.5f, -0.5f, -0.5f,  0.0f, 1.0f,
  37.  
  38.         -0.5f,  0.5f, -0.5f,  0.0f, 1.0f,
  39.          0.5f,  0.5f, -0.5f,  1.0f, 1.0f,
  40.          0.5f,  0.5f,  0.5f,  1.0f, 0.0f,
  41.          0.5f,  0.5f,  0.5f,  1.0f, 0.0f,
  42.         -0.5f,  0.5f,  0.5f,  0.0f, 0.0f,
  43.         -0.5f,  0.5f, -0.5f,  0.0f, 1.0f
  44.     };

其中每一行的前三个数对应了一个顶点的(x,y,z)坐标。你可能会问，一个正方体不是只有8个顶点吗，为什么这里有36行？这是因为，OpenGL以三角形的方式绘制物体。1个正方体由6个正方形面构成，1个正方形由2个三角形构成，1个三角形又有3个顶点，所以共需要定义6x2x3=36个顶点。

不用在意这些细节，总之我们可以发现，这个数组定义了从（-0.5,-0.5,-0.5) ~ (0.5,0.5,0.5)的正方体的顶点，如下图所示。

model矩阵：确定物体间的相对位置

在案例的main.cpp中，有这样一段代码：

  1.     glm::vec3 cubePositions[] = {
  2.         glm::vec3( 0.0f,  0.0f,  0.0f),
  3.         glm::vec3( 2.0f,  5.0f, -15.0f),
  4.         glm::vec3(-1.5f, -2.2f, -2.5f),
  5.         glm::vec3(-3.8f, -2.0f, -12.3f),
  6.         glm::vec3( 2.4f, -0.4f, -3.5f),
  7.         glm::vec3(-1.7f,  3.0f, -7.5f),
  8.         glm::vec3( 1.3f, -2.0f, -2.5f),
  9.         glm::vec3( 1.5f,  2.0f, -2.5f),
  10.         glm::vec3( 1.5f,  0.2f, -1.5f),
  11.         glm::vec3(-1.3f,  1.0f, -1.5f)
  12.     };
  13. // ....
  14.  
  15.         for (unsigned int i = 0; i < 10; i++)
  16.         {
  17.             // 为每个正方体计算model矩阵
  18.             // 初始化model矩阵为4x4的单位阵
  19.             glm::mat4 model = glm::mat4(1.0f);
  20.             // 平移cobePositions[i]
  21.             model = glm::translate(model, cubePositions[i]);
  22.             float angle = 20.0f * i;
  23.             // 绕轴(1,0.3,0.5)逆时针旋转20*i度
  24.             model = glm::rotate(model, glm::radians(angle), glm::vec3(1.0f, 0.3f, 0.5f));
  25.             //把计算好的model矩阵赋值给vertex shader中定义的model变量
  26.             ourShader.setMat4("model", model);
  27.             //绘制图形
  28.             glDrawArrays(GL_TRIANGLES, 0, 36);
  29.         }

可以将model矩阵理解为对平移、旋转、放缩操作的集合。比如，对cube[1]，先平移（2,5,-15）再绕轴旋转20度；对cube[2]，先平移（-1.5,-2.2,-2.5）再绕轴旋转40度……在这个for循环中（循环10次是因为案例中要产生10个正方体）通过对每个正方体计算model矩阵，我们确定了这10个正方体间的相对位置。

可以对cubePositions数组或者rotate函数中的角度与旋转轴进行修改，帮助理解model矩阵的作用。比如，我将rotate函数中的旋转轴改为（0,0,1），得到了这样的效果：

 view矩阵：确定物体与“相机”的相对位置

 之所以给相机打引号，是因为OpenGL中其实不存在专门的相机。gl_Position = projection * view * model * aPos这个式子也说明，mvp矩阵的作用对象其实都是物体的顶点，所谓相机只是一个为了便于理解而产生的概念，而view矩阵的目的就是确定物体与相机的相对位置。注意，此处的物体指的是全部的物体形成的集合，也就是案例中的十个正方体形成的组，而不是某个单一物体。

在main.cpp中，有这样一段代码：

  1.         // 初始化view矩阵为4x4的单位阵
  2.         glm::mat4 view          = glm::mat4(1.0f); 
  3.         view       = glm::translate(view, glm::vec3(0.0f, 0.0f, -3.0f));
  4.         // 把计算好的view矩阵赋值给vertex shader中的view变量
  5.         ourShader.setMat4("view", view);

此处设置的view矩阵非常简单，它仅仅告诉我们物体位于相对相机（0,0,-3）的位置上。如果将其view改为glm::translate(view, glm::vec3(0.0f, 0.0f, -5.0f));，可以看到物体看起来变得更远了，因为此时物体位于相对相机（0,0,-5）的位置上了。

我设置了更复杂的view矩阵，让物体位于相对相机（1,1,-5）的位置上，并绕z轴逆时针旋转了45度。

  1.         view       = glm::translate(view, glm::vec3(1.0f, 1.0f, -5.0f));
  2.         view       = glm::rotate(view, glm::radians(45.0f), glm::vec3(0.0f, 0.0f, 1.0f));

OpenGL的坐标系遵循右手定则，设置的时候不要写反哦。

 projection矩阵：将物体投影到相机

个人认为projection变换是最好理解的，虽然计算其变换矩阵比较复杂。简而言之，就是将位于视锥体内的物体”压扁“到近平面上。投影分为正交投影和透视投影。

正交投影

0fd7de1258244f85817ea6074f6ad3b3.png

要创建一个正射投影矩阵，我们可以使用GLM的内置函数glm::ortho：

glm::ortho(0.0f, 800.0f, 0.0f, 600.0f, 0.1f, 100.0f);

前两个参数指定了平截头体的左右坐标，第三和第四参数指定了平截头体的底部和顶部。通过这四个参数我们定义了近平面和远平面的大小，然后第五和第六个参数则定义了近平面和远平面的距离。这个投影矩阵会将处于这些x，y，z值范围内的坐标变换为标准化设备坐标。

透视投影

19ec68afc1634cf4b4c15da4bbfc839f.png

在GLM中可以这样创建一个透视投影矩阵：

glm::mat4 proj = glm::perspective(glm::radians(45.0f), (float)width/(float)height, 0.1f, 100.0f);

它的第一个参数定义了fov的值，它表示的是视野(Field of View)，并且设置了观察空间的大小。如果想要一个真实的观察效果，它的值通常设置为45.0f，但想要一个末日风格的结果你可以将其设置一个更大的值。第二个参数设置了宽高比，由视口的宽除以高所得。第三和第四个参数设置了平截头体的近和远平面。我们通常设置近距离为0.1f，而远距离设为100.0f。所有在近平面和远平面内且处于平截头体内的顶点都会被渲染。

在案例中采用的是透视投影，可以调整参数尝试下其他效果～

  1.         glm::mat4 projection    = glm::mat4(1.0f);
  2.         projection = glm::perspective(glm::radians(45.0f), (float)SCR_WIDTH / (float)SCR_HEIGHT, 0.1f, 100.0f);
  3.  
  4.         ourShader.setMat4("projection", projection);
