What is the difference between them? Which one is the best?

推荐答案

A Pixel Shader 是一个 GPU(图形处理单元)组件，可以编程为在每个像素的基础上运行，并处理照明和凹凸贴图等内容.

A Pixel Shader is a GPU (Graphic Processing Unit) component that can be programmed to operate on a per pixel basis and take care of stuff like lighting and bump mapping.

A Vertex Shader 也是 GPU 组件，也使用特定的类似汇编语言进行编程，类似于像素着色器，但面向场景几何体，并且可以执行诸如向对象添加卡通轮廓边缘等操作.

A Vertex Shader is also GPU component and is also programmed using a specific assembly-like language, like pixel shaders, but are oriented to the scene geometry and can do things like adding cartoony silhouette edges to objects, etc.

两者都不比另一个好，它们都有其特定的用途.大多数支持 DirectX 9 或更高版本的现代显卡都包含这些功能.

Neither is better than the other, they each have their specific uses. Most modern graphic cards supporting DirectX 9 or better include these capabilities.

网络上有多种资源可以帮助您更好地了解如何使用这些东西.NVidia 和 ATI 尤其是有关此主题的文档的好资源.

There are multiple resources on the web for gaining a better understand of how to use these things. NVidia and ATI especially are good resources for documents on this topic.
