摘要

•HLSL和Cg在语法上几乎相同•例外:Cg 1.3允许着色器“接口”，不大小数组•命令行编译器•微软的fxc .exe•编译到DirectX顶点和像素着色器组装仅•fxc /Tps_2_0 myshader。•cgc -profile ps2_0 myshader。cg•可以生成非常不同的组装!•驱动程序将重新编译代码•遵从性可能有所不同

High level languages for GPUs

• HLSL and Cg are syntactically almost identical • Exception: Cg 1.3 allows shader “interfaces”, unsized arrays • Command line compilers • Microsoft’s FXC.exe • Compiles to DirectX vertex and pixel shader assembly only • fxc /Tps_2_0 myshader.hlsl • NVIDIA’s CGC.exe • Compiles to everything • cgc -profile ps_2_0 myshader.cg • Can generate very different assembly! • Driver will recompile code • Compliance may vary
