HLSL语言是实现可编程管线着色程序的编程语言。HLSL语言具备高级语言所应有的特性，如变量、函数、结构化等。同时，HLSL语言的工作原理也和C++这样的高级语言一样，是将代码编译为“机器代码”之后再运行的。-Language is the HLSL shader pipeline programmable programming language. HLSL language with high-level language should have features such as variable, function, structure and so on. At the same time, HLSL language and also the working principle of C++ such as high-level language is to compile code for the " machine code"　and then running.
