irtual reality can serve to new product design, helping as an ancillary tool for engineering in manufacturing processes, new product prototypes, and simulation. Among other examples, electronic design automation, CAD, Finite Element Analysis, and computer-aided manufacturing are widely utilized programs.[citation needed] The use of Stereolithography and 3D printing shows how computer graphic modeling can be applied to create physical parts of real objects used in naval,[21] aerospace,[22] and automotive industries,[23] which can be seen, for example, in the VR laboratory of VW in Mladá Boleslav. Beyond modeling assembly parts, 3D computer graphics techniques are currently used in the research and development of medical devices for therapies,[24][25][26] treatments,[27] patient monitoring,[28] and early diagnoses[29] of complex diseases.
