设计OpenGL ES绘图代码有许多可能的策略,其全部细节超出了本文档的范围。渲染引擎设计的许多方面对于OpenGL和OpenGL ES的所有实现都是通用的。 调试和分析 Xcode和Instruments提供了许多工具来跟踪渲染问题并分析应用程序中的OpenGL ES性能。 三、配置OpenGL ES上下文 OpenGL ES的每个实现都提供了一种方式来创建渲染上下文...
通常,只有两种情况,OpenGL ES应用程序应调用glFlush或glFinish函数。 当您的应用移动到后台时,您应该刷新命令缓冲区,因为在应用处于后台时在GPU上执行OpenGL ES命令会导致iOS终止您的应用。 (请参阅实施多任务处理型OpenGL ES应用程序。) 如果您的应用程序在多个上下文之间共享OpenGL ES对象(如顶点缓冲区或纹理),则...

The sample code for theOpenGL ES 2.0 Programming Guideis now available for WebGL, Android 2.2, and iOS 4.2 (in addition to continued support on Windows OpenGL ES 2.0). Additionally, in order to make it easier to provide future updates, I have migrated all of the source to theopengles-bo...
由于《OpenGL ES 2.0 Programming Guide》原书第12章并没有提供相关的示例,为了加深理解,遂自己实现了一份C语言版本作为练习,希望能够帮助到同样喜欢OpenGL ES 2.0的同学。 废话不多说,直接上代码: #include <stdlib.h> #include <stdio.h> #include "esUtil.h" ...
OpenGL-ES 学习流程 论入门学习,DirectX比OpenGL友善得多,版本简单明了,装好SDK开VisualStudio就可以跑,文档案例齐全,省心省事。OpenGL有多麻烦?网上一搜,被告知需要glew;想在不同系统下快速搭建开发环境?再去找找glfw。搜个教程,又要求glut。开始写代码了,OpenGL里面没有内置数学库,... (展开) 6 0回应 六月...
“As a graphics technologist and intense OpenGL ES developer, I can honestly say that if you buy only one book on OpenGL ES 3.0 programming, then this should be the book. Dan and Budirijanto have written a book clearly by programmers for programmers. It is simply required reading for anyone...
Additionally, OpenGL ES 3.0 adds a new feature called transform feedback, which allows the vertex shader outputs to be selectively written to an output buffer (in addition to, or instead of, being passed to the fragment shader). For example, as covered in the transform feedback example in ...
