The topic of this final project is creating and optimizing 3D models for video games. Video games demand a number of requirements that every 3D model needs to meet in order for the video game to perform well. The importance of reducing the number of polygons of which the geometry consists of is described and the techniques used to achieve that are explained. Special attention is paid to the economical use of textures in achieving a pleasing appearance of the model. Softwares Blender and Unity were used in the practical part of the final project. The tools and benefits of using these softwares are listed. In the practical part of the final project, a 3D humanoid figure in the Blender softwer was created. Blender is a free and open source 3D creation tool that fully encompasses the 3D creation process: modeling, sculpting, texturing, animating, etc. Upon completion of character creation, a simple demonstration of character use was made in the Unity video game engine using animations downloaded from the Unity Asset Store. This simple demonstration was made to show how the charecter would look like in a full game.
