这段代码实现了一个基本的OpenGL程序，创建了一个窗口并渲染一个彩色三角形。以下是代码分析： 1. 初始化部分正确设置了GLFW和GLEW，使用核心模式OpenGL 3.3 2. 着色器程序创建流程完整，包含顶点和片段着色器 3. 顶点数据设置合理，使用VBO和VAO进行管理 4. 渲染循环结构正确，包含缓冲区交换和事件处理 需要注意的逻辑点： - 缺少着色器编译错误检查，应该添加glGetShaderiv和glGetProgramiv调用验证编译和链接状态 - 窗口创建后应该设置视口大小glViewport(0, 0, WIDTH, HEIGHT) - 没有处理窗口大小改变的回调函数，当窗口大小变化时可能导致渲染异常 [2025-05-25 16:08:38 | AI写代码神器 | 170点数解答]
