The feedWebGL2 software package enables parallel computations using a feature of HTML5/WebGL2 called Transform/Feedback. The Transform/Feedback mechanism can be used within Jupyter widgets or in other web components and applications for a special class of parallel computations called shader-like calculations, which can solve many problems well, but are unsuitable for some classes of parallel algorithms. This article describes the characteristics of shader-like calculations and how they can be created using the feedWebGL2 software package. The example programs use shader-like calculations for special purpose graphical stages in combination with standard WebGL graphics pipelines, and also use them for general purposes, such as matrix computations.

WebGL中用于高级图形和通用目的的明暗处理

feedWebGL2软件包使用称为Transform / Feedback的HTML5 / WebGL2功能启用并行计算。Transform / Feedback机制可以在Jupyter小部件中或在其他Web组件和应用程序中用于特殊类别的并行计算（称为“类似于着色器”的计算），该方法可以很好地解决许多问题，但不适用于某些类别的并行算法。本文介绍了类似于着色器的计算的特征，以及如何使用feedWebGL2软件包创建它们。示例程序将特殊的图形阶段与着色器类似的计算与标准的WebGL图形管道结合使用，并且还将它们用于一般用途，例如矩阵计算。
