本文详细分析了HGE库中Core模块的Demo与Graphics部分，探讨了开场Logo的显示逻辑以及Graphics的接口实现，强调了在使用引擎时尊重版权的重要性。同时，介绍了2D图形渲染的基本原理，如矩阵运算、投影矩阵设置和裁剪技术，其中裁剪通过调整投影矩阵实现视觉效果。文章引用《Windows游戏编程大师技巧》作为进一步学习2D图形实现的资源。

继续接着上次的，Core中的文件一个一个来。

顺便提一下demo，就是第一个cpp文件，上次说了这个是开场画面，想了下还是上代码一点一点说吧，随便提点怕说不清

ok，demo.cpp

他完成的事情是：把一进去那个logo画出来，停留一小会，然后滚蛋

#include "hge_impl.h"

#ifdef DEMO

hgeQuad dquad;//定义的一个区域数据结构，可以理解为一个方格，在这个方格里可以放我们想画的图片，画方格就行
float dtime;//demo停留时间


//这个很有意思，是把图片嵌入代码的方式，这是个位图，这样做的好处是它就包含在hge.dll里面，不用再配个图片跑的时候才载入了，想到于刻在了心里（=。=）
//这是人家的logo当然要无时不刻都有了。
