**8. Conclusion**

3D computer graphics gave the possibility to create a 3D world with scenarios, where immobilized persons can learn to handle the most common obstacles. System is supported for virtual headsets, therefore, immobilized persons can experience more authentic environment. Chapter represents 3D computer graphics used in an environment together with an explanation of why they were implemented that way. Virtual reality is a technology that supports such environments. As VR technology is relatively young and it is still evolving, it was needed to implement such 3D graphics, which will not compromise the smoothness of the simulator. Therefore, simulator is implemented with prioritization of smoothness over a realistic look. Chapter also focuses on such 3D graphics combinations to give the user the best experience.
