顶点这边 我看powerVR也就是说苹果也是如此 还有mali 目前看这俩平台的顶点数据都有这样一步优化 一个render pass的所有顶点shade的时候 先算pos 用这个结果拿最上一层顶点数据 只对这部分顶点做其它数据varyings的计算 这样cull那些顶点都不需要计算除了pos外的其它数据了 它接下来的说法我是比较困惑的 他说 这部分顶点数据是交错放置的 所有postion顶点数据pack一个buffer 其它non-pos数据包一起 这部分可以去ue里确认下 这是上层做的事情 还…

对于ARM Mali GPU,目前是支持OpenCL1.1,所以我们可以利用OpenCL来加速我们的计算. 一直以来,对于Mali GPU的OpenCL编程,一直没有环境来测试.好不容易弄到一个华为Mate7,却因为华为没有提供OpenCL driver(小道消息,华为下半年开始将会有OpenCL Drivert提供,拭目以待吧).目前测试过的手机有魅族MX4 pro T628是带有OpenCL Driver,这个还得多亏三星的猎户座芯片.对于安卓手机如果手机是Mali GPU(如果是T6xx以…

我知道这非常长,可是,我坚持看完了.希望有幸看到这文章并对图形方面有兴趣的朋友,也能坚持看完.一定大有收获.毕竟知道它们究竟是怎么"私下勾搭"的.会有利于我们用程序来指挥它们....(这是我加上去的) 原文从这里開始: 要说到设计的复杂程度,那还是CPU了!这个不用讨论,非常easy的道理你看看显卡芯片的更新速度和CPU的更新速度就可见一斑了.还是简单说说他们的设计原理吧. CPU: 可是,如今我要问一句:"什么是CPU?"我相信大多数人并不知道什么是CPU.当然,…

After the last post about texture samplers, we’re now back in the 3D frontend. We’re done with vertex shading, so now we can start actually rendering stuff, right? Well, not quite. You see, there’s a bunch still left to do before we actually start ra…

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…
