ABSTRACT
Ian D.Bishop and Eckart Lange Development happens fast in computer hardware-the famous Moore’s law suggests a doubling of capability every 18 months. At the time of writing there was opinion that the trend in graphics performance was an astonishing six-month doubling time. We have endeavoured, therefore, to provide information here that will retain currency because it refers to hardware or software issues that remain the same irrespective of speed of performance.
