Virtual reality comprises a large range of technologic and equipment (electronic equipment, hydraulic equipment, real-time computing systems, optic design), that governs sensations appealing to human senses (seeing, hearing, feeling). Among these, the visual sense is the most intensely used in virtual reality, because most pieces of information on the environment are obtained by seeing. The visual image is the essential component of virtual reality, enabling the user to identify the environment in which he is present, to orient himself and act and, thus, most research studies in the field of virtual reality were made in the field of graphics and image generation. Thus, the problem of virtual reality utilization in computer-aided design of technological devices has risen.
