The thesis is divided into several stages. The first phase is gathering of the templates for the 3D models. The second phase is the development of models. The work describes the process of making each of these models. The models are: fur of a shorthair cat, fur of a long-haired cat, feathers of birds from the family columbiformes, and a specimen of reptilian skin. The paper will describe the process of making each template in the program "Blender". Some models will be made through the particle sistem, while others will be a complex network of polygons. Each of the models will have a color. In complex polygons there will be drawn a layout for color. For models made with the particle system, color will be added through the settings for the particles. After completing the models the next faze is photography using a virtual camera built into the program. This procedure gives a two-dimensional representations of the model. These photos will be used for testing in the next phase of work. The third phase is the testing templates and models. When testing there will be by several parametars. It will include testing the appearance of the model, and compared with the original template by several parameters. The final phase consists of two analyzes. Analysis of the level of complexity for each model, and the total time of writing.
