WebHLSL has two syntaxes: a legacy DirectX 9-style syntax, and a more modern DirectX 10+ style syntax. The difference is mostly in how texture sampling functions work: The legacy syntax uses sampler2D, tex2D () and similar functions. This syntax works on all platforms. The DX10+ syntax uses Texture2D, SamplerState and .Sample () functions. Web技术标签： Directx 数学 HLSL 以下内容为根据DXSDK翻译，本人原创，转载需注明。因为网上一篇很早的内容不全，故根据官方SDK自己翻译了一份全的。
