we will continue the functionality of the hand tool with having a navigator panel which works as a map, we will also have a red rectangle which tells the user where he is actually viewing inside the whole form, also it can be moved to pan the form
This tip will introduce a library written in C++ that wraps up a 2d polygon triangulation algorithm with time complexity of O(N*logN), the algorithm works on both self-intersected and non self-intersected polygons.
in this tut we will create a technique to enable the user to control points within a drawn line, by drawing circles around points of the line , when the user clicks a circle he would control the corresponding point.
