| Medical virtual experiment takes a positive role in cultivating medical students’practical operation ability as an assisting means of teaching in current medicalexperiments. The construction of three-dimensional human body model is one of the mostimportant links in the process of the development of the medical virtual experiment; itaffects the learners’ learning efficiency. In terms of the present condition of thedevelopment of the medical virtual experiment, its simplicity and complexity hasrestricted the application and popularization in medical teaching. So the development ofmedical virtual experiment needs to seek the integration of a variety of ideas and methodsto ensure the technical implementation of medical virtual experiment to improve medicalstudents’ learning efficiency and promote the sustainability of medical virtual experimentin the medical teaching.The cross-technology of the virtual experiment is a comprehensive variety ofmodeling techniques, let each technology plays its respective advantages in the processof modeling to achieve complementary on the function and coherent effect in the contentin order to get a more efficient, scientific and economic way of3d human body modeling.The model of human body is an important part of medical virtual experiment, itdirectly impacts on the effectiveness of knowledge and learning efficiency and it isdifferent from general industrial modeling, the complexity of the human body structureputs forward higher request to the technology of virtual human body modeling. We notonly modeling the macro states and shapes of human body but also simulating itsmicrostructure in the process of modeling, a single technology is hard to meet theserequirements, however cross-technology on the basis of a variety of technologyintegration can reach the effect of high simulation, it will have a far-reaching significanceon the development of medical virtual experiment modeling.Based on sorting out and analyzing the idea of appropriate technology and the theoryof Edgar dale, I propose the concept of the development of medical virtual experiment using cross-technology. On the basis of this, I analyze the principle and process ofimplementation using cross-technology: use Photoshop which is one of the ubiquitoustechnologies to dispose of picture material and make texture; use3ds Max which is one ofmainstream3d modeling software and use3d auxiliary modeling software ZBrush toconstruct human body model; use UVLayout to make a scientific and reasonable texturecoordinate for complex model, so that we can make model match its texture perfectly. Onthe basis of theoretical study and the principle and process of implementation usingcross-technology, combine with the characteristics of the structure of the nervous system,teaching requirements and environmental restrictions, take the process of constructingthe model of human nerves for an example, choose appropriate technology fordevelopment adjusting measures to local conditions, and summed up the timing, methods,techniques and announcements of the use of cross-technology, to provide technicalsupport for the development of model in medical virtual experiment. |
