Design and implementation of a three-dimensional virtual gantry crane system of automatic control

21st century information engineering has achieved unprecedented development , computer technology as the core technology has been widely applied to various fields of social life . Virtual reality technology as a cutting-edge computer science technology, broadband networks , high-tech multimedia and integration of artificial intelligence , sino hoist the continuous development of technology, the construction of a virtual laboratory became possible to establish virtual experiments can greatly promote education development of information technology to improve the level of education development in China , especially for relatively scarce educational resources in the western region is more important. Currently virtual laboratory use more two-dimensional plane design approach , in terms of experimental realism, interactivity and teaching and the reality falls far short of the experimental effects , can not meet the needs of actual teaching. With greatly enhance the development of computer graphics technology and computer graphics performance ever achieved only on high-performance computer desktop virtual reality can now also running on an ordinary personal computer , virtual reality technology thus hoist gantry crane unprecedented popularity extent , also brought new vitality to the development of a virtual laboratory . This paper analyzes the drawbacks of traditional laboratory summarizes research status at home and abroad in terms of virtual experiments , the background to the process control laboratory for experimental teaching process automation professionals - tank experimental research.
