This paper presents the calculation method of a shape factor of human body model, shape factor distribution maps, etc. Using the measurements of human body's sections, the 3D human body model creation was performed. Consequently, the 3D human body models (four kinds : standing nude, standing clothed, seated nude, and seated clothed), which consist of triangles, could be created. In order to perform shape factor simulation of these models, the calculation algorithm of a shape factor using the scan line was developed. The program using this algorithm was able to calculate the shape factor distributions of the human body model on the wall. After calculating the effective radiation area of the human body model, the shape factors between the human body model and the rectangular plane ware determined.
