+  这篇文章介绍了如何使用OpenCV进行图像的加法运算。首先，通过包含OpenCV和iostream头文件，并使用std命名空间，开始编写代码。主函数中，读取两张图片，检查是否成功加载，并确保它们的尺寸相同。如果尺寸不同，将第二张图片调整为与第一张相同的大小。然后，调用add函数对两幅图片进行加法运算，并将结果存储在result矩阵中。最后，显示原始图片和加法运算的结果，并等待按键关闭窗口。代码已上传至自建的git仓库。

+opencv对图像的算数运算，感觉都大同小异，分为以下几种：加减乘除和位运算。
+
+| 函数                | 功能     | 应用场景       |
+|-------------------|--------|------------|
+| cv2.bitwise_and() | 按位与操作  | 掩码操作、图像分割  |
+| cv2.bitwise_or()  | 按位或操作  | 图像叠加       |
+| cv2.bitwise_not() | 按位取反操作 | 图像反色       |
+| cv2.bitwise_xor() | 按位异或操作 | 图像差异检测     |
+
+因为感觉都差不多，所以只把加法运算代码搬过来
+
+```cpp
+// 加法
+#include <opencv2/opencv.hpp>
+#include <iostream>
+
+using namespace std;
+using namespace cv;
+
+int main()
+{
+    string path1 = "../img/2.jpg";
+    string path2 = "../img/3.jpg";
+
+    Mat img1 = imread(path1);
+    Mat img2 = imread(path2);
+
+    if (img1.empty() || img2.empty())
+    {
+        cout << "无法读取图片，请检查路径！" << endl;
+        return -1;
+    }
+
+    if (img1.size() != img2.size())
+    {
+        cout << "尺寸不一致，正在自动调整 img2 的尺寸..." << endl;
+        // 将 img2 缩放到与 img1 相同的尺寸
+        resize(img2, img2, img1.size());
+    }
+
+    Mat result;
+    add(img1, img2, result);
+
+    imshow("Original Image 1", img1);
+    imshow("Original Image 2", img2);
+    imshow("Add Result", result);
+
+    // 等待按键后关闭窗口
+    waitKey(0);
+    destroyAllWindows();
+
+    return 0;
+}
+```

+  这篇文章详细介绍了配置OpenGL环境所需步骤，包括安装Visual
+  Studio、CMake和GLFW等关键组件，并提供了具体的配置方法和测试代码，旨在帮助读者顺利开始计算机图形学的学习之旅。
+date: 2026-04-02 04:52:16
+---
+
+最近要学计算机图形学，所以会用到`OpenGL`，配置环境有点繁琐，记录了下来。
+
+# 安装Visual Studio
+现在我们先来安装`Visual Studio`：[visual studio](https://visualstudio.microsoft.com/zh-hans/vs/)，下载后安装即可|在安装时选择“使用C++的桌面开发”，这样安装时就会安装C++的编译器了。
+![](https://pic.biss.click/image/2d3be78a-320f-41de-8773-e2fd7a2af66e.webp)
+
+# 安装 Cmake
+这个可选，因为我们可以使用`Visual Studio`的编译器`MSVC`来编译项目。
+`Cmake`是一个开源的跨平台软件构建工具，它可以生成不同系统的构建文件，比如`Makefile`，`Ninja`，`VS`项目文件等等。
+我们可以下载`Cmake`：[cmake](https://cmake.org/download/)，下载后安装即可。
+
+# 安装GLFW
+OpenGL有许多工具，比如GLFW，GLEW等等，这里我们安装GLFW。
+|工具|类别|主要职责|特点|
+|----|----|----|----|
+|GLUT|窗口管理 + 工具库|创建窗口、处理鼠标键盘、提供内置渲染循环。|古老、简单。使用“固定管线”（老旧技术），适合教学。|
+|GLFW|窗口管理库|创建窗口、处理输入、管理多个上下文。|现代、轻量。只管窗口和输入，不负责渲染逻辑，是目前的主流。|
+|GLAD|配置/加载库|加载 OpenGL 函数指针（连接驱动）。|底层必备。因为 OpenGL 函数在显卡驱动里，需要它来“找”函数地址。|
+
+## 下载GLFW 和 glad
+`GLFW`是一个开源的跨平台`C/C++`窗口管理库，它可以创建窗口、处理输入、管理多个上下文。
+下载`GLFW`：[glfw](https://www.glfw.org/download.html)，下载后解压即可。
+
+
+
+## 创建项目与配置
+用`Visual Studio`创建一个空的`C++`项目，然后添加GLFW的目录到项目中。
+在项目属性中添加GLFW的目录到“C/C++->General->Additional Include Directories”中。
+如图所示：
+![](https://pic.biss.click/image/0097e9f0-d0ab-4bd1-b9de-c774cee0d4ef.webp)
+
+## 测试
+
+创建一个`main.cpp`文件，内容如下：
+```cpp
+#include <glad/glad.h>
+#include <GLFW/glfw3.h>
+#include <iostream>
+
+// 顶点着色器源码
+const char* vertexShaderSource = "#version 330 core\n"
+    "layout (location = 0) in vec3 aPos;\n"
+    "void main() {\n"
+    "   gl_Position = vec4(aPos.x, aPos.y, aPos.z, 1.0);\n"
+    "}\0";
+
+// 片段着色器源码
+const char* fragmentShaderSource = "#version 330 core\n"
+    "out vec4 FragColor;\n"
+    "void main() {\n"
+    "   FragColor = vec4(1.0f, 1.0f, 1.0f, 1.0f);\n" // 白色
+    "}\n\0";
+
+int main() {
+    // 1. 初始化 GLFW
+    glfwInit();
+    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
+    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
+    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
+
+    // 2. 创建窗口
+    GLFWwindow* window = glfwCreateWindow(800, 600, "Simple OpenGL", NULL, NULL);
+    glfwMakeContextCurrent(window);
+    gladLoadGLLoader((GLADloadproc)glfwGetProcAddress);
+
+    // 3. 编译着色器
+    unsigned int vertexShader = glCreateShader(GL_VERTEX_SHADER);
+    glShaderSource(vertexShader, 1, &vertexShaderSource, NULL);
+    glCompileShader(vertexShader);
+
+    unsigned int fragmentShader = glCreateShader(GL_FRAGMENT_SHADER);
+    glShaderSource(fragmentShader, 1, &fragmentShaderSource, NULL);
+    glCompileShader(fragmentShader);
+
+    unsigned int shaderProgram = glCreateProgram();
+    glAttachShader(shaderProgram, vertexShader);
+    glAttachShader(shaderProgram, fragmentShader);
+    glLinkProgram(shaderProgram);
+
+    // 4. 定义三角形顶点数据
+    float vertices[] = {
+        -0.5f, -0.5f, 0.0f, // 左下
+         0.5f, -0.5f, 0.0f, // 右下
+         0.0f,  0.5f, 0.0f  // 顶部
+    };
+
+    unsigned int VBO, VAO;
+    glGenVertexArrays(1, &VAO);
+    glGenBuffers(1, &VBO);
+
+    glBindVertexArray(VAO);
+    glBindBuffer(GL_ARRAY_BUFFER, VBO);
+    glBufferData(GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW);
+
+    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 3 * sizeof(float), (void*)0);
+    glEnableVertexAttribArray(0);
+
+    // 5. 渲染循环
+    while (!glfwWindowShouldClose(window)) {
+        glClearColor(0.2f, 0.3f, 0.3f, 1.0f); // 深青色背景
+        glClear(GL_COLOR_BUFFER_BIT);
+
+        glUseProgram(shaderProgram);
+        glBindVertexArray(VAO);
+        glDrawArrays(GL_TRIANGLES, 0, 3);
+
+        glfwSwapBuffers(window);
+        glfwPollEvents();
+    }
+
+    glfwTerminate();
+    return 0;
+}
+```
+如果能运行成功应该就没问题了。

+  这篇文章介绍了三种直线扫描转换算法：DDA算法、中点画线算法和Bresenham算法。
+  DDA算法通过计算直线起点和终点的坐标差值来确定步数和增量，依次绘制直线上的点。算法实现简单，适用于任意直线，但精度较低。
+  中点画线算法仅适用于斜率为0或1的直线，通过计算中点和斜率来确定直线上的像素点，效率较高。
+  Bresenham算法根据直线的斜率和误差项来确定像素点的位置，适用于任意直线，且精度高，但实现稍复杂。
+date: 2026-04-11 19:01:02
+---
+
+这篇文章来介绍直线扫描转换算法
+# DDA数值微分线段算法
+## 算法简介
+数值微分法即DDA法(Digital Differential Analyzer)，是一种基于微分方程来生成直线的方法。在计算机图形学中，并没有线段的概念，而是一个个像素点组成了线段。
+
+DDA法生成线段的步骤一般如下：
+
+1. 有了起始点（$x_1，y_1$）和终点（$x_n，y_n$）；
+2. $$\Delta x =|x_n-x_1|, \Delta y=|y_n-y_1|$$
+3. 比较$\Delta x$和$\Delta y$的大小；
+    steps=$\Delta x$和$\Delta y$中较大者；
+4. $$step_x=\frac{\Delta x}{steps}，step_y=\frac{\Delta y}{steps}$$
+## 算法实现
+DDA算法实现如下：
+```cpp
+#include <cmath>
+#include <iostream>
+#include <GL/glut.h>
+
+// 窗口宽度和高度
+const int WIDTH = 640;
+const int HEIGHT = 480;
+
+void drawDDALine(int x1, int y1, int x2, int y2) {
+    float x = x1;
+    float y = y1;
+
+    // 计算差值
+    int dx = x2 - x1;
+    int dy = y2 - y1;
+
+    // 确定步数，取 dx 和 dy 中绝对值较大的那个
+    int steps = std::abs(dx) > std::abs(dy) ? std::abs(dx) : std::abs(dy);  //三元表达式
+
+    // 计算每一步的增量
+    float xIncrement = (float)dx / steps;
+    float yIncrement = (float)dy / steps;
+
+    // 开始绘制点
+    glBegin(GL_POINTS);
+    glVertex2i((int)round(x), (int)round(y)); // 绘制起点
+
+    for (int k = 0; k < steps; k++) {
+        x += xIncrement;
+        y += yIncrement;
+        // 将浮点坐标四舍五入取整转换为整数像素坐标
+		std::cout << (int)round(x) << ", " << (int)round(y)<<"\n";
+        glVertex2i((int)round(x), (int)round(y));
+    }
+    glEnd();
+}
+
+// 显示回调函数
+void display() {
+    drawDDALine(0, 0, 50, 20);
+    glFlush();
+}
+
+// 初始化 OpenGL 设置
+void init() {
+    // 设置背景颜色为白色
+    glClearColor(1.0f, 1.0f, 1.0f, 1.0f);
+
+    // 设置投影矩阵为 2D 正交投影
+    glMatrixMode(GL_PROJECTION);
+    glLoadIdentity();
+    // 定义可视区域，左下角(0,0)，右上角(WIDTH, HEIGHT)
+    gluOrtho2D(0.0, WIDTH, 0.0, HEIGHT);
+}
+
+int main(int argc, char** argv) {
+    // 初始化 GLUT
+    glutInit(&argc, argv);
+
+    // 设置显示模式：单缓冲、RGB 颜色模式
+    glutInitDisplayMode(GLUT_SINGLE | GLUT_RGB);
+
+    // 设置窗口大小和位置
+    glutInitWindowSize(WIDTH, HEIGHT);
+    glutInitWindowPosition(100, 100);
+
+    // 创建窗口
+    glutCreateWindow("DDA算法");
+
+    // 注册回调函数
+    glutDisplayFunc(display);
+
+    // 初始化设置
+    init();
+
+    // 进入主循环
+    glutMainLoop();
+
+    return 0;
+}
+```
+
+# 中点画线算法
+## 算法简介
+只考虑当直线的斜率$|k|< 1$时的情况，假设现在有一条直线$(x_1,y_1,x_2,y_2)$,那么第一个点一定是$(x_1,y_1)$无疑，下一个点的$x$坐标为$x_1+1$,$y$坐标要么为$y1$要么为$y1+1$。关键在于每次取下一个点时，是取前一个的$y1$呢，还是$y1+1$,这时一定是取直线上点最靠近的那个了，而判断取哪个点就用到了中点，我们将中点代入直线中 $d=F(x_1+1,y_1+0.5)=a \cdot (x_1+1)+b \cdot (y_1+0.5)+c$。
+
+1. 如果直线$d>=0$，则取下边的点也就是$(x_1+1,y_1)$。
+2. 如果直线$d<0$,则取上边的点也就是$(x_1+1,y_1+1)$。
+
+它的实际过程就是这样每次根据前边的点判断下一个点在哪，然后进行打亮，但这样每次判断的时候都得代入直线方程计算太麻烦了，我们将这俩种情况分别代入直线方程中可以找出规律：
+
+1. 当直线$d>=0$时，经过化解得$d_1=d+a$;
+2. 当直线$d<0$时，经过化解得$d_2=d+a+b$;
+3. 初始值$d_0=a+0.5b$。
+
+也就是说每次的增量要么为$a$,要么为$a+b$,那么这样判断的时候就简单多了，因为我们每次只是判断它的正负。所以给等式同时乘2，将其中浮点数0.5化为整数，这样硬件操作时无疑更快了。

+#  Bresenham算法
+## 算法简介
+假设我们需要由$(x_0, y_0)$这一点，绘画一直线至右下角的另一点$(x_1, y_1)$，x,y分别代表其水平及垂直坐标，并且$x_1 - x_0 > y_1 - y_0$。在此我们使用电脑系统常用的坐标系，即$x$坐标值沿$x$轴向右增长，$y$坐标值沿$y$轴向下增长。
+
+因此x及y之值分别向右及向下增加，而两点之水平距离为$x_{1}-x_{0}$且垂直距离为$y_{1}-y_{0}$。由此得之，该线的斜率必定介乎于$0$至$1$之间。而此算法之目的，就是找出在$x_{0}$与$x_{1}$之间，第$x$行相对应的第$y$列，从而得出一像素点，使得该像素点的位置最接近原本的线。
+
+对于由$(x_0, y_0)$及$(x_1, y_1)$两点所组成之直线，公式如下：
+$$y-y_{0}={\frac {y_{1}-y_{0}}{x_{1}-x_{0}}}(x-x_{0})$$
+因此，对于每一点的x，其y的值是
+$${\frac {y_{1}-y_{0}}{x_{1}-x_{0}}}(x-x_{0})+y_{0}$$
+因为$x$及$y$皆为整数，但并非每一点$x$所对应的$y$皆为整数，故此没有必要去计算每一点x所对应之$y$值。反之由于此线之斜率介乎于$1$至$0$之间，故此我们只需要找出当$x$到达那一个数值时，会使$y$上升$1$，若$x$尚未到此值，则$y$不变。至于如何找出相关的$x$值，则需依靠斜率。斜率之计算方法为$m=(y_{1}-y_{0})/(x_{1}-x_{0})$。由于此值不变，故可于运算前预先计算，减少运算次数。
+
+要实行此算法，我们需计算每一像素点与该线之间的误差。于上述例子中，误差应为每一点$x$中，其相对的像素点之$y$值与该线实际之$y$值的差距。每当$y$的值增加$1$，误差的值就会增加$m$。每当误差的值超出$0.5$，线就会比较靠近下一个映像点，因此$y$的值便会加$1$，且误差减$1$。
