In this paper, the human musculoskeletal model based on the medical images of the Korean standard male and the computer graphics based simulation technology with biomechanical analyses are presented. The virtual human model consists of three components. The model component includes the development of anatomically accurate geometric models with physiologically relevant material data. The analysis component includes various types of mechanical. In the simulation component, task-oriented graphic simulation would be performed for virtual evaluation, test, measurement, design, and planning. Three biomechanical analyses with graphic simulation using the virtual Korean model were performed; the surgical simulation of bone fracture surgery, the biomechanical evaluation of surgical implant in knee, and the graphic visualization and simulation of tennis play. In conclusion, the developed virtual Korean model of the musculoskeletal system would have lots of potentiality for biomechanical research and development in various fields, such as medical industry, automobile, ergonomics, or nuclear industry.
