DOOM 4™采用OpenGL 3.0 API开发

OpenGL 3.0™ 技术资料

GPU Gems 3 是 nvidia公司的 GPU Gems系列的延续，其中大部分文章的作者都是Nvidia公司的，研究范围相等广泛，技术也相当不错，给出了当前GPU发展的最新技术，跟另一巨头AMD.ATI(好别扭)所出的ShaderX系列可以说代表了当前最先进的Real-Time渲染技术。记得前两本都是公司第一时间从亚马逊网站邮购回来的，这次不知道能不能先睹为快。nvidia公司在其网站给出了18、30、38章供下载。

OpenGL 3.0是OpenGL ARB组织今年的重头戏之一。于2007年8月8日正式发布，其specification还要经过协商讨论、正式定稿后，然后由Khronos Group组织进行为期30天的评估后，于9月底对外公开整个规范。其中，OpenGL、OpenGL|ES、GLSL都进行了相应的调整和升级。主要的改变有以下一些部分。

GLSL部分的改变包括：将attribute、varying关键词更改成in、out、inout；将单个的uniform变量组装成uniform buffer性质的common结构；内置固定管线的状态不再tracked；sampler2D数组使用image2DArray和filter来代替；预处理增加##和#include语句；OpenGLES增加了lowp、mediump、highp限定词；矩阵增加row_major限定词，允许使用行优先矩阵了；增加了switch语句。

将在结合CgFX的基础上，增加一个创建rendering eEffects的框架---glFX。其目的是为了更好、更容易的创建特效。glFX将支持OpenGL2.1、OpenGL3.0、OpenGL ES 2.0等。并对OpenGL3.0作出优化。
OpenGL3.0的改变包括：消除遗留的一些功能，如过程式编程接口(Begin/End）、固定管线的T&L功能和纹理应用方法、客户端的顶点数组方式、选择模式、反馈模式、求值器、累计缓存等；全面转向对象模型，用于提高性能和共享灵活，基本上所有能成型的东东都叫Object的了。如：State Object、Data Oobject、Container Object、Vertex Array Object、Buffer Object、Shader Object、Program Environment object、Program Object、Texture Filter Object、Image Object、Format Object、Rasterization Object、Per-Sample Operations Object、Framebuffer Object、Save/Restore Object、Pack/Unpack Object、Sync/Query Object等。
就总体而言，感觉3的改变相当大，不论是概念、内容、还是接口。
