Abstract : The field of computer graphics applied to three-dimensional space is introduced through a discussion of perspective transformations, data structure, contour lines, and the problem of hidden-line removal. The transformation of three-dimensional coordinates into two-dimensional picture-plane coordinates is developed for twelve degrees of freedom, allowing the simultaneous movement and rotation of both the object under view and the observer. Basic concepts and requirements for the structure of data and ideas for the use of contour lines are discussed as a relative part of the field of three-dimensional computer graphics. An algorithm for the removal of hidden lines is explained for the case where the objects under view can be assumed to be constructed of bounded plane surfaces. (Author)
