前言

上一章大体了解了lwjgl的结构，lwjgl集成了多个底层图形库和系统api库，本身并不提供上层抽象，我们在使用的时候只需要选择自己需要使用的库，并按照对应库的api进行开发即可。

模块依赖

如何配置依赖，lwjgl提供了依赖项生成工具，方便选择所需的依赖库和版本等配置。 lwjgl提供的依赖及项目生成工具

https://www.lwjgl.org/customize

可以通过上面这个地址选择哪些依赖项并生成就可以下载依赖项配置，演示使用maven配置pom.xml，将pom.xml中的配置配置到自己的项目中即可。

通过配置项生成的pom.xml依赖项示例

功能实现

简单使用opengl创建和渲染窗口使用glfw进行处理窗口事件监听

代码实现

测试及运行

执行main方法即可看到效果
