TDD An Interactive Three Dimensional Drawing Program for Graphical Display and Lightpen

  • R. J. Hubbold

Abstract

This paper describes a set of FORTRAN programs written to investigate the use of a CRT graphical display with lightpen as a three dimensional sketchpad. The programs are operational on an ICL 4l30 computer with an Elliott 4280 graphical display unit, and they form part of a more general investigation into using displays for 3D problems, including Coons’ patch techniques for surface modelling.
