Introduction

This project has a more or less educational goal on programming 3D real time graphics desktop application, from scratch. I am making this project on my own in order to have more practice in Computer Graphics. It doesn't mean that I am inventing comletely all ideas from scratch. I am still referencing to some other resources that have a quick and deep guide on certain features and systems. Project is written in C++ with OpenGL API and other libraries. You will find a list of libraries below.
