Design And Research Of3D Visualization Microcomputer Interface Of Virtual Experimental System

"Microcomputer Principle and Interface Technology" is the electronic specialties’basic compulsory course, which is highly demanded in engineering practice. There are some disadvantages of the traditional experiment, and virtual experiment is a good solution to the problems of high cost of traditional experiment and the changeless of test module, it provides an independent experimental platform. This thesis focus on the shortages of the original virtual experimental study some new aspect on this field by using VC++with3DMAX and OpenGL technology to design and development of3D visualization microcomputer interface of virtual experimental system. The system presents the experimental element by three-dimensional, using the OBB method for collision detection, which avoids the element in the process of moving collision, to solve the problem of experimental distortion, and realization of component interaction function, including a circuit connection, movement, rotation, delete function.This paper first introduces the research status and the trend of development of virtual experiments, and discuss the virtual experiment of computer interface system, then put forward a hypothesis that a perfect experimental system should contain experimental view, program design, circuit design, experimental operation, library management, test report and other six major function modules, and describe the process of the operation in Microcomputer interface virtual experiment system;3D visualization of virtual experimental system requires several related techniques; put forward a kind of virtual experiment element mathematical model and visualization method, and based on the virtual3D experiment element8255parallel interface and a traffic light and made visualization modeling; the detection of the test element is very important in the experimental collision, so this paper also explores the direction of oriented bounding box collision detection experimental device. Finally, using the related research data achieve3D visualization of virtual experiment of computer interface system, via the example of8255interface to control traffic lights to introduce system which is based on the virtual experiment. Experiments show that the3D visualization of the microcomputer principle and interface technology of virtual experiment system in experimental teaching has a practical value.
