Construction Of Real-time Interactive Virtual NMR Lab Based On Virtools And Flash

Virtual Reality is a new type of multimodal human-computer interaction mode. People can feel the Virtual simulated by computer in various ways based on this mode. The developed of Virtual Reality is a interdiscipline based on computer graphics, computer simulation technique, human-computer interaction technique, multimedia technology and sense technology. Now, virtual reality technology, multimedia technology and network technique have the best prospect.Virtual lab is a new mode based on virtual reality technology. Users can finish the experiment under it just as they did in reality lab, ever more, they may get better learning effect through it. Now the developed of virtual lab cover many fields, such as physics, chemistry, medical science, military, machinery. And there are more and more tools and methods to develop virtual lab. There are many tools can be used to design the virtual lab, including three-dimensional and two-dimensional tools, and they all have their own strong point, so we should develop a new way to integrate the advantage of three-dimensional and two-dimensional.As an exploration in the development of the integrate three-dimensional and two-dimensional virtual lab model and technique, this issue choose the NMR experiment to do this research. The NMR experiment mainly including two parts:operate the instrument and handle the spectrogram in the workstation, just like many other instruments such as AAS,AES,GC-MS and so on. So the develop of virtual NMR lab can use for reference to those instruments.In order to achieve the three-dimensional simulation of operational control on NMR experiment process, choosing 3ds Max/Virtools and Flash for modeling and interaction, a relying on the virtual character, whole scene, open, high-interactive, integrate three-dimensional and two-dimensional immersed dual liquid system virtual NMR lab is constructed. On the NMR experiments of several samples is studied, using VSL program modules and Flash ActionScript 2.0 codes realized the parameter's communication between the real-time controlling interaction and the workstation, and simulated the drawing of the spectrum of NMR. In meanwhile, added the analysis the spectrum of NMR.The simulation system realized a selection of samples and solvent, local enlargement, real-time trace evaluation, drawing spectrogram and analysis the spectrogram, simulating the whole experiments. And enhanced the availability of the system.
