http://www.gamedev.net/topic/496785-deferred-rendering-and-hdr/ Quote: Original post by jstrohYeah I've been reading about people saying "oh you can only do it if the device supports fp16 texture blending" but it's pretty simple to just add to a…

目前所有的移动设备都使用的是 Tile-Based Deferred Rendering(TBDR) 的渲染架构.TBDR 的基本流程是这样的,当提交渲染命令的时候,GPU 不会立刻进行渲染,而是一帧内所有的渲染命令积攒起来,最后统一渲染.在渲染到 FrameBuffer 的时候,也不是依次执行所有的命令将 Fragment 结果填充到 FrameBuffer 中.而是在 GPU 内部有着叫做 Tile 的高速渲染器,这些 Tiles 虚拟的将 FrameBuffer 分割成小块(光栅化后得到很…

Deferred 框架下的AA 前面说过Deferred 框架下无法使用硬件AA.这句话不严谨: Deferred Shading在G-Buffer之后,物体几何信息全被抛弃了,导致兴许每一个像素都独立计算,所以不能使用硬件AA: 可是:Deferred Lighting,在Shading Pass阶段.物体会被再次渲染一遍,此时打开硬件MSAA,肯定是能用的(虽然光照部分取自lighting Pass阶段得到的texture,没能享受到AA.但对终于结果影响非常小). 所以.总结来看,Defe…

先来看一张网上广为流传的<杀戮地带2>典型的Deferred Shading的G-Buffer组织: 这里补充解释下几个点: 不存Position,而由depth和屏幕像素坐标反推出来.參考:http://www.derschmale.com/2014/01/26/reconstructing-positions-from-the-depth-buffer/ Normal能够仅仅存两个分量,算法多种多样.float16 精度足矣.參考:http://aras-p.info/texts/Comp…

Deferred lighting separate lighting rendering and make lighting a completely image-space technique. This is very different the forward rendering. At first as the limitation of the hardware, we could make per-object lit by max number of 8 lights at on…
