This particular postgraduate thesis is divided into two sections. The first one involves the creation of a three-dimensional model of any object we could have around us. The second section includes incorporating this three-dimensional model into an application, a game in this case, as a virtual object.
In the first section, we are going to examine all the available means to create a three-dimensional model, following the method of photogrammetry. We are going to analyze the properties of some and delve into one, which we will use to create our own model.
In the second part, we will access the platform Unity and following simple steps, we will develop an application, in which our three-dimensional model will play a leading part.
More specifically, we will demonstrate how to insert the new model into the game in stages, as well as how to form the game environment, how to incorporate the rest of the models in our game, how these will interact and finally, we will explain the rationale behind each step.
It will be necessary to write a code in C# programming language, which we are going to analytically explain. With the aforementioned code, we will be able to control every move of our player, the behavior of the objects, the system of point collection and many other features.
The result includes an arcade game that can be played on a PC, in a web environment.
Our main objective is to implant the idea that every object that someone might have in their surroundings could constitute a virtual entity in a future application, which they could create on their own, using a PC and a camera or a mobile phone. All the above does not require expensive special equipment or programs. Overall, it is a good start for anyone who would like to experiment in this particular field.
