在论坛里,经常看到有些网友说中国的游戏开发别的都不缺,就缺好的创意策化.其实,中国游戏开发什么都缺,游戏程序设计开发,美工,3D,AI都很落后.
目前国外流行的都是3D游戏(如半条命2),开发该类游戏的重要基础之一就是计算机图形学,而且是real-time rendering(实时绘制).因此游戏程序开发与一般程序设计不同,有一定的门槛,不象写信息管理系统程序,无论谁学几句SQL语句,便能操刀上阵了.
我不知道大家有没有深入地研究过计算机图形学. 要真正理解计算机图形学，必须灵活地运用高等数学，线性代数，计算数学等知识,还要有较好的英语（因为资料大部分是英文的）, 当然还要学习大量的图形学算法。（很多算法并不是一成不变的，在真正实现时有很多的技巧）. 所以我说搞计算机图形学,要求的门槛较高，要求理论与实践并举。
要开发3D游戏,首先要学习计算机图形学,但由于各种原因,国内现有的计算机图形学书籍都比较初级,没有深入的.而且都是比较传统的.2000年左右,随着显卡技术(GPU)的革命性突破,实时绘制大行其道,国外这方面的书籍很多,可在中国却看不到,我国没有把外版书直接放在书店卖的传统(怕太贵卖不掉,一本书要五百人民币左右);要等翻译吧,国内一年在这方面也翻译不了几本,而且等到翻译出来了,有些技术也成昨日黄花了,再说翻译的水准也不行(估计翻译的人员自己也不太懂);等影印版吧,便宜,可国外出版社哪肯把能卖大价钱的畅销书贱卖给我国.
国内学术界的杂志关于计算机图形学的文章很少,不象国外有很本多专门的计算机图形学杂志,而且高水平的很少.于是国内这方面的印刷资料基本上没有.国内也有些人编过3D的编程书籍,但太小儿科,这样的书没什么帮助.
大家都看过水世界,泰坦尼克号,我们都为电影中那些以假乱真的电影特技深深地折服.那些计算机生成的高度真实感的海洋让人看不出破绽.国外的计算机图形学研究和实际的应用贴得很近，电影特效、动画中所用到的都是最新的研究成果。反观国内，学术界和CG界就像是两个陌生人一样。从无来往，也从不关心对方的存在。
而且还有一个奇怪的现象,学术杂志,书籍很少提到那些国际上知名的图形学研究专家,新的技术,在非技术性的CG杂志上却有介绍,在CG杂志上有不少图片来自于SIGGRAPH(世界图形学年会).再看看国内学术界编的那些图形学教材,在"正文"里根本不提到SIGGRAPH这几个字.为什么有这种现象???
常看英文文献的网友,会去国外下载高水平论文(如SIGGRPAH),但由于这些论文都需要一定的背景知识,否则很难看懂.这些背景知识散见于以前的论文和书籍.前面说过图形学外文书籍国内是不容易找到的,有些论文在网上只有会员才能下,一般人只能看个摘要.当然还有一个途径,花钱还是能买到的,贵啊.(国内的一些大图书馆有这项服务)
所以,在国内一个业余爱好者研究计算机图形学的环境很差, 由于资料的限制,学习中充满着艰辛. 对于一些深入的课题,比如说绘制具有高度真实感的水流,海洋,高山,火焰,烟雾,布料,没有相关的系统性资料. 有一些图形学中相当经典的图书,论文,作业余爱好者,是看不到的. 由于3D知识不普及,周围很少有人与你有同样的兴趣. 说到3D,就知道3DMAX,MAYA,很少有人去想一想这背后的图形学原理.永远只能跟在外国人之后亦步亦趋.有些网友虽然会依葫芦画瓢写VERTEX SHADER,PIXEL SHADER来达到特殊的效果,但对于这些程序背后的原理却一点儿不清楚,direct3D下有很多例子,能理解的人又有几个,HDRI,Subsurface Scattering这些术语背后后技术更是很少有人涉及.可能有人会说,既然你想学,可以直接去AMAZON买原版书啊.可是一个人处于学习能力最旺盛时候,往往是在学生时代,但那个时候也是最缺钱的时候,一本原版书需要五六百…
由此造成国内民间对计算机图形学的认识很肤浅,没有普及,大部分计算机专业的学生都不太懂,运动员都是从群众中选拔出来的,群众体质较差,运动员也好不到哪儿去.可想而知专业的3D游戏程序设计水平会高吗?--- 空中楼阁.
而国外不一样,一个业余爱好者占有的资料会比大学教授都多,水平也就更高.(看看国外那些个3d引擎)国内大部分的游戏开发论坛都没有实质性内容,很肤浅.
所以希望出版社或相关部门能意识到这个问题,出版社最好能直接引进高水平,有深度的计算机图形学图书(不要老是VC,VB,JAVA),语言是工具,只有运用到各个专门领域才能发挥更大的作用.
这些都是高水平的real-time rendering书籍,看看国外有这么多,那儿的业余爱好者多幸福.这些书国内基本上没有,国内的业余爱好者有多悲惨.(其中部分书籍有英文电子版,但一些经典的好书往往没有电子版)

国内无书可读的环境一日不改变,说什么提高中国游戏开发水平都是空谈.
中国人很聪明,为什么在学术上一直落后?一个很重要的原因是,一个人大学本科毕业,研究生期间,教师便没有更多的东西教给他了,他即使想自学,图书馆里也没有什么新的,深入的图书可供阅读.而国外就不同,研究生期间,有大量令人兴奋的知识在等着他来学.
No one knows,and each person can have a significant effect on the way the future turns out.There is no one future,no course that must occur.You create it.
摘自<real-time rendering>的最后一句.
You create it.我很欣赏这句话.
国内的学者,是吝啬这句话的,好象学术只是大学里的专利.
最后我还是以You create it.来结尾.
