What is the simplest (and easiest, although that's subjective) algorithm for drawing solid (as in a single, solid color--no texture mapping) 2D polygons in memory? What is the most efficient method?
I am not interested in using the GPU or any rendering method, as the output of my program will not be to the screen.
回答1:
The Polygon Fill Teaching Tool will show you a very nice, simple algorithm for drawing filled polygons of any complexity.
I've implemented it for embedded graphics, and it's actually a neat (and fun!) algorithm.
