I am working my way threw a windows programming book and reach a point i need some info. I have come accross the word delta. What is the definition of that term. (Its not explained in the book, only used. This especially for the lineclipping algo).
I am now at the trapping the mouse section. You can do so by absolute postion (fine, no problems) or by relative deltas?(heh :))
Can someone give me some info on what the latter means....(There is a graphic in the book, but i dont get it)
