Research On The Control System Of Oil Extraction Joint Station Based On PLC

virtual training simulation is training simulation based on virtual reality technique,which is the computer mapping to the taining process. As the virtual technique became more and more mature,virtual human will be embedded in the environment of virtual training simulation, as the expresstion the trainee in the environment of virtual training.Trainee can interact with virtual human in the virtual environment,immersing in it,studying and training.The expressing method of human body model are analyzed and studied in this paper,and selected...
