图形学opengl作业-简单机器人&&我的世界简化版

凭借着图形学的课，这学期有幸接触了opengl，稍微搞了一些东西，也算入了个门。

下面的是参考这位大牛，在原作的基础上增添了行走操作、肢体旋转、复位、背景音乐、武器选择。

直接看代码就行，和上一篇一样没什么高深的算法，不过对于初学者来说要花时间熟悉语法。

背景音乐用的fmod，fmod用多个声道时网上没什么比较清晰的教程，建议用bass。

(刚开始为了找解决方案，还特地买了个mp3转mid转换器，这软件是可以用的，就是还是解决不了根本问题，顺便贴出来分享下click here~)

本篇两个作业用的vs2013，一些库和头文件都需要自己配。

先上几个效果图吧，一大坨代码附在最后。(大神请绕道)

-----------------------------------完结分割线----------------------------------------------

接下来就是厉害的东西了，主笔是我同组的另外两位大神，我是最水的一个。

一些比较难的碰撞检测、阴影效果、地形管理(地形是无限延伸的)都是他们的成果，除此之外还有重力设置方块渲染相机aabb包围盒啥的，框架的搭建也是属于继承那种偏向于项目的东西，我是第一次接触这些东西，就不班门弄斧了，就做了个音效界面还被嫌弃T T。。

这是我上大学以来见过的最牛逼的东西，老实说刚开始听到ys说要做这个时我是震惊的，没想到真的做出来了2333666。。

对我来说也没什么别的想法了，能和这些大神合作本身就是一种幸运。

下面是效果图，由于我最水，就不上代码了，需要的私聊我吧。
