The topic of this final work was the creation of a 3D model in the Blender program. When creating the 3D model, tools and modifiers were used to change the shape and design of the objects themselves. The paper will show the basic functionalities and use when creating 3D models, it will be shown on several examples when creating 3D models using basic tools and modifiers. It will also describe the application in the industry in the development of games, films, and animations. The process of creating a 3D model will be described and additionally a 3D model created using the program code will be shown. The introductory section describes the Blender software and its history. After that, the application in the industry is described, the initial scene with the user interface and the basic view modes, options, and the first display in the software when opening are described. As a practical part, a 3D model of a house was created, 3D models created using the same modifiers, creation of simple 3D models using program code, and creation of 3D models of two trees with different appearances. Each model is made using a different technique or programming code.
