Convex Hull Visualizer

2D visualization of the step-by-step process of various Convex Hull algorithms. Made with C++, using Raysan5's Raylib for rendering, and RayGUI (an immediate mode GUI module meant to work with Raylib) for the GUI. Demo video can be found here

Implementation

• The concrete implementations of many of these algorithms usually involve quite a few nested loops, and I don't want to dirty up my update loop by placing a render() call inside it.
• Thus, the approach taken was to, within the algorithm computing the convex hull, push an instance of IAnimFrame2D (which contains information about what to draw) for each step of the convex hull, into a queue.
• During one update iteration, all the steps of the convex hull are computed and the cached
• Then, for each render() call, you can unload the IAnimFrame2D's one-by-one from the queue to display

Extra

• At the time of writing, there are only 2 algorithms concretely implemented (Jarvis March & Graham Scan).
• However, the system is extensible. You only have to implement IConvexHull2D, as well as raise an event to set the current algorithm to be used.
• Using state pattern for the control flow of the application (Idle, Generating Points, Animating....)
