Design And Implementation Of Virtual Laboratory Based On3D And Virtools

With our country entering the information society, enterprises have higher requirementsfor the talents of innovation ability and practice ability. Colleges and Universities are the baseof cultivating talents with innovative ability and practice ability. Since their laboratoryteaching has many restrictive factors, the improvement of the quality of experimental teachingand the level of scientific research are seriously impacted. Therefore, transformingexperimental teaching way is to be imperative. As a new experimental teaching mode, VirtualLaboratory which based on Information Technology provides a better way to solve the lack ofexperimental equipment and places and meet the personalized needs of students in theexperiment. Therefore, the construction of virtual laboratory is very important for improvingthe existing experiment condition.The paper discusses and analyzes the commonly used3D modeling tools and virtualreality platform. Maya and Lightwave3D are more suitable for establishment of the film andtelevision animation model,3ds Max is suitable for indoor design and game. Compared withthe Virtual Reality Platform and VRML, the developing difficulty of Virtools is lower andVirtools is easier for non computer professionals. Therefore the paper uses3ds Max modelingtool to realize3D modeling virtual laboratory and uses Virtools to realize the interactiondesign of3D models. Finally, the virtual laboratory platform is constructed in Windowsenvironment and provides experiment operating module of virtual laboratory system.The experiment operating module provides four functional modules of the angleswitching, the experiment introduction, the automatic demonstration and manual experiment.The angle switching module provides multiple perspectives, including top view, right view,front view and perspective four angles, to observe experiment scene, experimental instrumentsand experimental process. Using the experiment introduction module users can easily view theexperimental principle, experimental procedures and so on. Using the automatic demonstrationmodule and manual experiment module users not only can watch the whole experiment process can also hands-on practice. Using the experimental operation module of carbondioxide experiments validate the feasibility of the method of using three-dimensionalmodeling technology and virtual reality technology to build a virtual laboratory that proposedin this paper.
