Draw the convex hull with Canvas and Javascript

An algorithm to determine the convex hull of a set points is explained in the book Computational Geometry by Mark de Berg, Otfried Cheong, Marc van Kreveld en Mark Overmars (Mark ftw!). I saw my chance to implement this algorithm with Javascript and the Html5 canvas. The code can be found be..

Segment Intersection with JavaScript and Red Black Trees

This is probably the most advanced algorithm I ever programmed. At first sight calculating an intersection isn’t difficult, from a set of segments you can make all possible combinations and calculate the intersection point for each combination with some simple math. As the book “Computat..
