Graduation work is formed out of two parts that I will describe through this short concept. The head part of this thesis is 3D modeling in a program called Blender [1], more detailed explanation will be in the following chapter. I’ve decided to create my own models in Blender [1] because it’s very compatible with Unity game engine [2]. Also it’s easier to edit, precisely scale objects and add textures in Blender [1]. The tail or the second part is making a simulation in Unity game engine [2]. I’ve decided to implement my 3D models in Unity [2] so that I could present plain models used in a 3D realisation with real physics of space and time. Unity [2] also has “World editor” or projecting models in real time, but it’s made of basic shapes that you are not able to model. Inside the Unity [2] you are creating the logic for your object to work inside the simulation. The logic is focused on Object-oriented programming in C# [3] (C sharp) that I will be explaining in details a bit later in this thesis. I’ve decided to write a graduation work thesis on this theme because I want to improve in C# O-O programming [3] and also 3D modeling. Given that I had college studies in both basic C programming language [4] and 3D modeling in Autocad [5]. I wanted to expand my knowledge
