Three-dimensional human display model

Abstract

A two-dimensional computer graphic display of a three-dimensional model depicting a human being is presented. The major body segments of the model are represented as non-uniform elliptic cylinders. The shadow outlines of these cylinders are displayed on the terminal screen and connected by circular arcs and straight lines to produce a realistic representation of a human being in any position. This human model was developed for the display of results of three-dimensional simulation programs which calculate the positions of an occupant during vehicle impact. However, it is well suited to any other type of human motion. The approach allows the user to select the viewing orientation and was designed for low cost computer and graphic terminal systems.
