对五角星进行纹理贴图的全部代码

好的，以下是对五角星进行纹理贴图的完整代码，其中使用了OpenGL 3.3及以上版本和GLFW库：

#include <GL/glew.h>
#include <GLFW/glfw3.h>
#include <SOIL/SOIL.h>
#include <iostream>

// 顶点着色器代码
const GLchar* vertexShaderSource = "#version 330 core\n"
    "layout (location = 0) in vec3 position;\n"
    "layout (location = 1) in vec2 texCoord;\n"
    "out vec2 TexCoord;\n"
    "void main()\n"
    "{\n"
    "    gl_Position = vec4(position, 1.0);\n"
    "    TexCoord = texCoord;\n"
    "}\0";

// 片段着色器代码
const GLchar* fragmentShaderSource = "#version 330 core\n"
    "in vec2 TexCoord;\n"
    "out vec4 color;\n"
    "uniform sampler2D texture1;\n"
    "void main()\n"
    "{\n"
    "    color = texture(texture1, TexCoord);\n"
    "}\n\0";

int main() {
    // 初始化GLFW库
    glfwInit();

    // 设置OpenGL版本和模式
    glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 3);
    glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 3);
    glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
    glfwWindowHint(GLFW_RESIZABLE, GL_FALSE);

    // 创建窗口
    GLFWwindow* window = glfwCreateWindow(800, 600, "Texture Mapping", nullptr, nullptr);
    glfwMakeContextCurrent(window);

    // 初始化GLEW库
    glewExperimental = GL_TRUE;
    glewInit();

    // 设置视口大小
    glViewport(0, 0, 800, 600);

    // 加载顶点和片段着色器
    GLuint vertexShader = glCreateShader(GL_VERTEX_SHADER);
    glShaderSource(vertexShader, 1, &vertexShaderSource, NULL);
    glCompileShader(vertexShader);

    GLuint fragmentShader = glCreateShader(GL_FRAGMENT_SHADER);
    glShaderSource(fragmentShader, 1, &fragmentShaderSource, NULL);
    glCompileShader(fragmentShader);

    // 创建着色器程序
    GLuint shaderProgram = glCreateProgram();
    glAttachShader(shaderProgram, vertexShader);
    glAttachShader(shaderProgram, fragmentShader);
    glLinkProgram(shaderProgram);
    glDeleteShader(vertexShader);
    glDeleteShader(fragmentShader);

    // 绑定顶点数组和索引数组，创建VAO和VBO
    GLfloat vertices[] = {
        // 顶点坐标           // 纹理坐标
        -0.5f, 0.0f, 0.0f,    0.0f, 0.0f,
        0.5f, 0.0f, 0.0f,     1.0f, 0.0f,
        -0.25f, 0.5f, 0.0f,   0.0f, 1.0f,
        0.0f, -0.5f, 0.0f,    0.5f, 1.0f,
        0.25f, 0.5f, 0.0f,    1.0f, 1.0f
    };

    GLuint indices[] = {
        0, 1, 2,
        1, 3, 4,
        3, 2, 4
    };

    GLuint VAO, VBO, EBO;
    glGenVertexArrays(1, &VAO);
    glGenBuffers(1, &VBO);
    glGenBuffers(1, &EBO);

    glBindVertexArray(VAO);
    glBindBuffer(GL_ARRAY_BUFFER, VBO);
    glBufferData(GL_ARRAY_BUFFER, sizeof(vertices), vertices, GL_STATIC_DRAW);
    glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, EBO);
    glBufferData(GL_ELEMENT_ARRAY_BUFFER, sizeof(indices), indices, GL_STATIC_DRAW);

    glVertexAttribPointer(0, 3, GL_FLOAT, GL_FALSE, 5 * sizeof(GLfloat), (GLvoid*)0);
    glEnableVertexAttribArray(0);
    glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 5 * sizeof(GLfloat), (GLvoid*)(3 * sizeof(GLfloat)));
    glEnableVertexAttribArray(1);

    glBindVertexArray(0);
    glBindBuffer(GL_ARRAY_BUFFER, 0);
    glBindBuffer(GL_ELEMENT_ARRAY_BUFFER, 0);

    // 加载纹理图片
    GLuint texture;
    glGenTextures(1, &texture);
    glBindTexture(GL_TEXTURE_2D, texture);

    int width, height;
    unsigned char* image = SOIL_load_image("texture.png", &width, &height, 0, SOIL_LOAD_RGB);

    glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGB, GL_UNSIGNED_BYTE, image);
    glGenerateMipmap(GL_TEXTURE_2D);
    SOIL_free_image_data(image);
    glBindTexture(GL_TEXTURE_2D, 0);

    // 渲染循环
    while (!glfwWindowShouldClose(window)) {
        // 清空颜色缓冲区
        glClearColor(0.2f, 0.3f, 0.3f, 1.0f);
        glClear(GL_COLOR_BUFFER_BIT);

        // 绑定纹理
        glBindTexture(GL_TEXTURE_2D, texture);

        // 绘制五角星
        glUseProgram(shaderProgram);
        glBindVertexArray(VAO);
        glDrawElements(GL_TRIANGLES, 9, GL_UNSIGNED_INT, 0);
        glBindVertexArray(0);

        // 交换缓冲区和轮询IO事件
        glfwSwapBuffers(window);
        glfwPollEvents();
    }

    // 释放资源
    glDeleteVertexArrays(1, &VAO);
    glDeleteBuffers(1, &VBO);
    glDeleteBuffers(1, &EBO);
    glDeleteProgram(shaderProgram);
    glDeleteTextures(1, &texture);

    // 关闭窗口并终止GLFW库
    glfwTerminate();
    return 0;
}

这份代码实现了五角星的纹理贴图，您可以将纹理图片保存为"texture.png"并放在代码所在的目录下，然后使用以上代码进行编译和运行。
