结合CUDA范例精解以及CUDA并行编程.由于正在学习CUDA,CUDA用的比较多,因此翻译一些个人认为重点的章节和句子,作为学习,程序将通过NVIDIA K40服务器得出结果.如果想通过本书进行CUDA编程,又不太懂CUDA和GPU的架构,可以将这个博客作为入门博客(但是希望你能有些基础,因为我介绍的并不是特别全面,只是捡了一些我困惑很久后来明白的知识点,如果完全不懂GPU的话,建议通读本书和介绍GPU的架构的书),我尽量在一个月更新完这本书的中文内容(部分)并补充一些自己的认识.欢迎大家评论…
Welcome back!    This post deals with the second half of pixel processing, the “join phase”. The previous phase was all about taking a small number of input streams and turning them into lots of independent tasks for the shader units. Now we need to…

http://anandtech.com/show/2549 Now that NVIDIA’s has announced its newest GPU architecture (the GeForce GTX 200 series), interesting architectural details are popping up on the web. The best writeup I’ve found is by AnandTech. In the past, such detai…
BACKGROUND The evolution of graphics rendering technology has led to the development of procedural techniques for describing various steps in the rendering process. Procedural geometry is useful as a mechanism for producing arbitrarily complex geomet…
At this point, we’ve sent draw calls down from our app all the way through various driver layers and the command processor; now, finally we’re actually going to do some graphics processing on it! In this part, I’ll look at the vertex pipeline. But be…

Unity中 Image Effect 是Post Processing的一种方,Unity自身也提供很多Effect效果供使用.Image Effect的使用官方文档做了很多介绍,这里重点Post Processing 做一些介绍. 1. Post Processing workflow Render the scene to a render target / texture (screen-size, usually same format) Reset render target - e…
一.GPU:图形处理器,Graphics Processing Unit 显卡的处理器就是图形处理器.与CPU类似.   GPU和CPU的区别? 1.CPU主要是为了串行指令设计,GPU则是为了大规模的秉性的计算而设计. 2.从并行的角度来看,CPU并行针对于指令集并行,而GPU的并行是针对大规模运算的. 3.同样面积的芯片:CPU上更多的放置缓存和控制部件,而GPU上放置的是更多的运算单元.   二.渲染管线 渲染管线也叫渲染流水线,就是告诉GPU一堆数据,然后得到一个二维的图像. 渲染管线主…

建立一个基本的屏幕后处理脚本系统 屏幕后处理,顾名思义,通常指的是在渲染完整个场景得到屏幕图像后,再对这个图像进行一系列操作,实现各种屏幕特效.使用这种技术,可以为游戏画面添加更多艺术效果,例如景深.运动模糊等. 因此,想要实现屏幕后处理的基础在于得到渲染后的屏幕图像,即抓取屏幕,而Unity为我们提供了这样一个方便的接口OnRenderImage函数.它的函数声明如下: MonoBehaviour.OnRenderImage(RenderTexture src,RenderTexture de…
