functions file isn't called on main

[dennisbett]

I tried running the code but the compiler logged errors showing that a lot was not defined. I noticed you didn't call "functions.cpp" in main... I tried but it still didn't work. please fix, I wanna see ray tracing on my potato pc

It compiles for me...

Are you sure that funtions.h, funstions.cpp and man.cpp are all in the same directory?

If you are using Visual Studio you'll have to add functions.h and functions.cpp in header files section. Right click on header files and click add existing items. Then select functions.h and functions.cpp.
