"imagine" is a verb, as in "imagine a pink elephant". I think you mean 
image.
If so, what is wrong with the output image? Or do you want the ray 
information? In that case, look at the functions in render.cpp, 
particularly trace_pixel().

It would be a lot easier to help you if you would give some hint as to 
what you are doing...
