如何在OpenGL中绘制纹理

// 加载纹理图像
GLuint textureID;
glGenTextures(1, &textureID);
glBindTexture(GL_TEXTURE_2D, textureID);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_S, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_WRAP_T, GL_REPEAT);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
int width, height, channels;
unsigned char* image = stbi_load("texture.jpg", &width, &height, &channels, 0);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGB, width, height, 0, GL_RGB, GL_UNSIGNED_BYTE, image);
glGenerateMipmap(GL_TEXTURE_2D);
stbi_image_free(image);

// 生成纹理坐标
float vertices[] = {
  // 位置            // 纹理坐标
  -0.5f, -0.5f, 0.0f, 0.0f, 0.0f,
  0.5f, -0.5f, 0.0f, 1.0f, 0.0f,
  0.0f,  0.5f, 0.0f, 0.5f, 1.0f
};

// 绘制纹理
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, 5 * sizeof(float), (void*)0);
glEnableVertexAttribArray(0);
glVertexAttribPointer(1, 2, GL_FLOAT, GL_FALSE, 5 * sizeof(float), (void*)(3 * sizeof(float)));
glEnableVertexAttribArray(1);
glBindVertexArray(0);

glBindTexture(GL_TEXTURE_2D, textureID);
glBindVertexArray(VAO);
glDrawArrays(GL_TRIANGLES, 0, 3);
