Stefano Website

Today I am happy to communicate that I open a new website about myself.

You can find at this link:


In this way you can know a little more about me.
For now the website has four main section:

  • Programming: I illustrate my programming skills and the projects available to the public.
  • Academic: In this area you can learn more about my accomplishments at Aalborg University as PhD Student and Research Assistant.
  • Education: The level of my education and the languages that I am and I will be able to speak.
  • Contact: The best ways that you can use to contact me.

From every page it is possible to download my CV. If you are more interested about my academic career until now, you can even download my academic CV from the section “Academic”.

I plan to keep this website updated with new projects and ideas.
Don’t worry! Follow this blog and I will keep you updated!

Fractals with Java

Hello everybody!

Today I created a new program in Java to create self similar sets. This are a type of fractals generated by rotations, translations and shrinking. However pictures are worth thousands of words. Let me to give some examples!

Likes leaves
Pythagoras tree
Pythagoras tree

The slider on the left are used to create your fractal on the right. Here the meaning of any sliders:

  • S indicates in how many way we want to repeat our fractals. For example for the Pythagoras tree we use two ways.
  • Times indicates how many times we want to repeat our pictures.

The user needs to be careful on using the “Times” slider because the number of points will increase exponentially.
In general, by using a little of math, we know that we have (S+1)^Times squares, so 4(S+1)^Times points. For example, for S = 2, Times = 10, our picture will represents 3^10 little squares.

  • For any function S we need to assign a rotation in degrees (with “Grade”), a shrinking in percentage (with “Size”) and a translation (in x with “X axis” and in y with “Y axis”).
    For example if we have Grade=45, Size=75, X axis=100, Y axis=-50, it means that we rotate our square of 45°, our new picture will be 75% the original one, and it will moved on the right of 100 pixels and on the bottom of 50 pixels.

You can download this small Java programs from here: Link v1.0 (9 KB) (old version with black fractals)

Link v1.1 (10 KB)
+ Added at the bottom a save button to save your fractals in .png files
+ Now the fractals are in red
+ Correct small mistakes

Note: To open a jar file in Windows, you must have the Java Runtime Environment installed.
