I'm doing a demo where i need to know if two lines ( x1,y1,x2,y2 first x3,y3,x4,y4 second line ) are cross. Otherwise, i need a line colision algorithm, i have one but i'm sure that using math i can obtain a better performance.
I found the following page useful:
Let me know if that helps
nice page, it just helped me out with a problem... bookmarked !
Hmmmmm having to write a piece of code that solves simulataneous equations is apparent. I may have a go at that soon.
