跪求一个OpenGL的编程~~编一个3D的球体，有光照阴影，200+行，发我邮箱里，谢~

跪求一个OpenGL的编程~~编一个3D的球体，有光照阴影，200+行~~！！
其实可以有其他的东西像旋转啦，缩放啦之类的，在保证光照阴影的前提下随便加~~不过不要太多。。。
亲们，一定要200+行啊~~！！
最好每步都有解释，声明：我是小白。。。不过有书可以查，但我还是小白。。。
所有财富值奉上~~~！！！谢过各位大神啦~~！！！
邮箱：lmeat@sina.com~~~~
再次感谢大神~~

Answer 1

《NEHE的教程》上有那么多例子可以供你参考。。

追问

我勒个去。。。我是小白。。。我要是有时间就自己学了。。。我也想学啊，可是没时间啊。。。现在为了这玩意通宵了三个晚上了，伤不起了。。。。跪求啊。。。

按经纬度,一圈圈来.20分,只能给你这么多.
