The undderwater vehicle NAUTILUS is prepared by students of WOiO PG for the SubRace 2018 competition. The works involve the design and construction of the vehicle, however not all the problems related to the configuration of the equipment can be solved without building of  the prototype. The project includes the visualization of various variants of the configuration of propulsion, steering and observation devices of the vehicle, based on provided 3D models and assessment of their usability based on the subjective feelings of the vehicle's pilot. Visualization carries out the pilot's point of view inside the vehicle, in the aquatic environment with its characteristic optical features. It should be carried out in the CAVE environment in the Immersive 3D Visualization Lab.
