First of all, I am no expert, and therefore my tutorial might not be of real value to many of you. I will not go into detail regarding the setup of the OpenGL work environment in Visual Studio (my IDE of choice), nor will I discuss the basics of OpenGL here. If we don’t, and is indeed in the Mandelbrot set, we simply keep iterating forever! Implementation So, to visualize the Mandelbrot set, we implement the following algorithm:Īdditionally, we must implement some sort of maximum number of iterations above which we interrupt the algorithm and assume the number is in the set. And another, infinitesimally larger or smaller, might take ten billion iterations of the process before. One choice of might cross after the fifth iteration, like we have seen above. Second, even the numbers which do not belong in the set show this chaotic behavior. It’s impossible to say whether two close numbers belong to the set or not, as the complex numbers along it’s boundary are chaotically being thrown around, either remaining within a distance of from the origin or being flung out. Instead, although this fractal exhibits some repeating themes, it is closely linked to chaos. You can keep zooming in on a fractal and you will never find some clear boundary. First, the Mandelbrot set is a fractal - a “self-similar” shape with a complex topology. There are two interesting observations to make here. And since this number is smaller than, is in the Mandelbrot set. Clearly, this series tends to grow, but only very slowly, approaching the value. One can see that has a modulus of, and, hence is not in the Mandelbrot set. Is the modulus of, its distance from the origin of the complex plane, below ? If yes, then is in the Mandelbrot set!Īnd so on and so forth. Take the result of this (let’s call it ) and plug it back into the function. Feed it to the function, where the initial value of. In a future post we will implement some elementary controls that will enable us to move around and zoom in & out, and we will also play around with the shaders to make the fractal look more stunning. In this first part, we set up everything in order to render the scene and write a shader that draws a visual representation of the famous fractal. In this two-part series I will show you how to visualize the Mandelbrot set using modern OpenGL.
