The work is divided into 3 phases. The first phase involves the creation of models and scenes. The second deals with camera animation in space, while the third phase deals with the illumination of different types of models with different materials. This work describes the procedures for creating many models in the scene, in the 3D program "Blender". Some models make polygon networks, while other models are made by simulation of particle systems. This work also shows designed 2D technical drawings of a house.After the modeling process is followed, their installation on the scene. After that, the procedure of illuminating and testing the appearance of the model in the scene and their photography using the camera in the program. By rotating the camera on the path and photographing in key moments, the program as a result gives a number of images that are processed by Blender's video processing. The final phase of the work consists of images of different models illuminated by all the light sources that the program offers. Based on these images, an survey is conducted, which includes several parameters for model testing - photorealistic, by comparing the images of the model taken in 3D Blender with different lighting. The aim of this work is to investigate Blender's photorealistic images and interior animation as well as the best light for the photorealistic model. Study and examine which materials and textures are best used for this purpose, also rendering options, as well as computer configurations. The hypothesized hypothesis is that the survey results show that Blender is strong enough to be able to use it for creating photorealistic interiors and models. Of course, the goal is to prove or kill the hypothesis.
