ProtoShade is a fragment (pixel) shader prototyping and design utility for the OpenGL ES Shading Language, with an emphasis on rasterizer special effects design, to differentiate from existing "viewport-sized quadrangle" fragment shader design utilities.
The user might use the application to prototype lighting algorithms, or to design unique special effects which are projected onto a three-dimensional model. The program supplies four example shader programs, and five models.
ProtoShade是OpenGL ES着色语言的片段(像素)着色器原型和设计工具，重点是光栅化器特殊效果设计，以区别于现有的“视口大小的四边形”片段着色器设计工具。
用户可以使用该应用程序来制作照明算法的原型，或者设计独特的特效，并这些特效被投影到三维模型上。该程序提供了四个着色器示例程序和五种模型。
