In the autumn four-month period of the 2015/2016 course, I studied a subject called Interaction and Design Interfaces (IDI) at FIB (BarcelonaTech).
On this subject, I did lab sessions each week where I learned OpenGL and Qt basic concepts. On the OpenGL Labs I learnt to represent 3D figures like Homer's and Patricio's and more things. And on the Qt Labs I learnt to create and design interfaces with Qt Designer, and also I learnt the mechanism of slots.
As I like to share all my labor done, I leave the repository with all I managed to do here.
Thank you very much for your time!
