延迟着色的渲染管线优化

传统的GPU渲染方法是前向渲染,在当前的实时渲染领域中,一种叫做延迟着色的新管线利用了硬件的多渲染目标特性进行两个阶段的管线处理,在逐像素光照计算之前就完成了所有的可见性测试,将像素填充率降到最低。然而,延迟着色需要大量的视频存储空间,而且不能高效地渲染半透明物体,针对应用中的这些局限性提出可行的解决方案。

Rendering Pipeline Optimization of Deferred Shading

Traditional method of GPU rendering is forward rending.In the current field of real-time rendering,a new pipeline called deferred shading utilizes multiple render target of feature GPU to realize two-stage pipeline processing.In this way,all of the visibility tests are done before per-pixel lighting calculation,which minimizes the pixel fill rates.However,deferred shading requires a large amount of video storage space,and can’t render translucent objects efficiently.To solve the technique limitations when applied,proposes some feasible solutions.
