Shader模型综述

Review of Shader Model

近年来随着计算机技术广泛应用于3D游戏、三维重建等领域,如何通过适当的shader模型去更加真实地表现现实世界的各种光影效果成了研究的热点。现在比较流行的4种shader模型为:①固定着色模型;②平面着色模型;③Gouraud着色模型;④phong着色模型。文章对这些模型进行了介绍,强调了各种模型的适用场合并对比了4种模型的优劣,最后探讨了着色模型的发展方向。

With the computer technology widely used in the areas of 3D games, three-dimensional reconstruction and etc. in recent years, how to choose an appropriate shader model to show various light and shadow effects in real world more truly has become a research hotspot. At present there are four more popular shader models： constant shading, flat shading, Gouraud shading and phong shading. These models are introduced, their applicable occasions are emphasized and their advantages and disadvantages are compared. Finally, the development direction of shader model is explored.
