Next section. Confusingly, tiled deferred rendering can apply to the deferred rendering or shading technique as well as the name of an architecture. This renderer would render each of those tiles individually, then save the resulting image somewhere. g. The immediate-mode custom resolve uses a compute kernel to Tile Based Deferred Rendering. Next steps. Using Tile-Based Deferred Rendering (TBDR)# The usual rendering technique on most GPUs is known as Immediate Mode Rendering (IMR) where geometry is sent to the GPU, and gets drawn Tile-based rendering is not specific to PowerVR architectures. Tile Based Rendering (TBR) Tiling is the process of binning post-transform geometry data into small rectangular regions, called tiles. This Mesa code has been successfully tested on DG2/Alchemist Arc Graphics as well as upcoming . Rasterization and fragment processing then occurs The tiles only change when a new level is loaded, and the sprites are changing all the time. . Immediate mode renderers work in a very straightforward manner. The Immediate An analysis of two Nvidia graphics cards reveals that they use a tile-based process to render images on a screen instead of the typical line-by-line method. Modern desktop GPUs do have early-z tests, so if you sort the geometry and draw it front-to-back you can still get most of the bandwidth minimization of a TBDR, and many non Early in the development of desktop GPUs, several companies developed tiled architectures. 在介绍分块渲染之前，先介绍一下什么是渲染。 如上图，将 GPU专栏(四) 基于块的渲染(Tile Based Rendering) IMG使用了基于块的渲染管线，而且是更进一步，名为TBDR, 在这之前，我们先来了解一下TBR, 这些都是移动端GPU常用到的技术。 基于tile的渲染还可以结合FBC技术进 文章浏览阅读1.
