Human body surface area and volume are important factors in human thermoregulation. The aim of this diploma thesis is to create a multisegmented model of the human body that serves for estimation of surface area, volume and mass of the human body and surface area and volume of segments of the human body. Multisegmented model constituted by us divides body to 13 segments from which the trunk segment is modeled three different ways (cylinder with ellipse base, cuboid and cylinder) and therefore creates three variants of our model. Dimensions were chosen for the model to function properly on living people and also on skeletal material. A multisegmented model and other models for estimation of surface area, volume and mass of the human body are tested by using 3D scans of the whole body of 20 individuals. Anthropometry in the virtual environment was used. From our variants of the multisegmented model, the model cuboid appears to be the most accurate one in the estimation of surface area and volume of the human body, when in the estimation of surface area mean percentage absolute difference was under 5 % and in the estimation of body volume was under 10 %. The model cuboid has the second smallest mean percentage absolute difference in the estimation of surface area of the body and the smallest mean...
