COMPUTER-GENERATED PERSPECTIVE PLOTS FOR HIGHWAY DESIGN EVALUATION

THE TECHNIQUES AND MATHEMATICAL BASIS ARE DESCRIBED FOR PRODUCING COMPUTER-GENERATED PERSPECTIVE PLOTS OF HIGHWAYS FOR DESIGN EVALUATION. THE PLOTS ARE EITHER PRODUCED ON A DIGITAL INCREMENTAL PLOTTER OR DISPLAYED ON A CATHODE RAY TUBE (CRT) OR MICROFILM RECORDER. ANIMATION EFFECTS MAY BE PRODUCED BY PHOTOGRAPHING SEQUENCES OF VIEWS AS PRODUCED ON THE CRT DISPLAYS OR AS RECORDED ON MICROFILM. A UNIQUE HIDDEN LINE ALGORITHM IS DESCRIBED WHICH WAS SPECIFICALLY DEVELOPED FOR DATA DERIVED FROM HIGHWAY DESIGN PROCESSES. THE METHODOLOGY FOR PRODUCING PHOTO-PLOT MONTAGES, WHICH CONSISTS OF SUPERIMPOSING COMPUTER-GENERATED PLOTS ON GROUND PHOTOGRAPHS, IS GIVEN. RESULTS OF FIELD TEST EVALUATIONS ARE PRESENTED FOR PHOTO MONTAGES PRODUCED USING A PHOTO-THEODOLITE AND ALSO NON-METRICAL CAMERAS. /FHWA/
