Hi, all
    I am trying to write the reflected ray to a file. Firstly, I thought
that I could get the reflected ray from the reflect() function in
lighting.cpp file, so I wrote some code in the function to realize it, but
it did not work. I found that this function was not called when I pushed the
"RUN" button. I do not know the reason. Where can I find the reflected ray?

Thanks
Wu Yang
