LWJGL入门指南：序章
LWJGL入门指南：安装LWJGL或生成maven或gradle依赖与第一行LWJGL代码
LWJGL入门指南：一个“超级”简单的3D射击游戏demo


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

测试及运行
执行main方法即可看到效果

在jme3跑一些涉及图像处理如渲染等操作的时候，在有些机器上可能会出现如下的错误

这可能是显卡不支持opengl1.x所致，前段时间发现在台式机上跑那些例子没问题，但换成在笔记本上GT425M独显是跑老是报错，最后切换成集成显卡就可以了，呵呵，我也不清楚是不是这个原因造成的，太底层的东西不好懂
