For this to work it is necessary to have NVAPI available on your system. The 'prelude' functionality in the Slang API allows for text to be inserted before any Slang code generated code is output. If the input source uses an NVAPI feature - like the methods above - it will output code that *assumes* that `nvHLSLExtns.h` is included. The following code from `render-test-main.cpp` sets up a suitable prelude for HLSL that includes `nvHLSLExtns.h` with an absolute path. |
