| summary |
This paper gives an account of works recently undertaken by the Department of Architecture of Mons Polytechnic School (Belgium) about a program of computer-assisted design. That program, written in FORTRAN, has been elaborated with the object of drawing perspective architectural scenes on digital plotters or graphic printers and of eliminating hidden lines from these scenes. Two algorithms, that yield good results for automatic search of observer's position in terms of orientation and for the computation of hidden lines in case of numerous segments and opaque surfaces, are presented. Some graphic examples are provided. An algorithm of previous classifying of segments and opaque surfaces is propounded. The precision of calculations and the magnitude of tolerances for parametric operations of comparison are discussed. The use of APL to introduce, modify or correct data is approached; in this way, a survey of potential application of APL for solid modeling is suggested.
