I am reading a book on DirectX. In it there are some advanced topics. I can understand and follow the code when the author explains the difficult functions and so on. Then when I look at his sample source code, everything looks familiar, but I am not exactly sure of the variable or why this function needs to be called. I understood it when the author explained it to me, but i havent internalized everything. Do I need to memorize every aspect of the code, or can I just go back to the explainations when I impliment the code or have trouble, in essence using the book as a reference? Thanks.
