Linear Codes for Real-Time Colour Graphics

In this paper, the problem of 'hidden - surface' elimination is considered. It is shown that a new linear surface- filling algorithm leads to some simple techniques for hidden-surface removal. Necessary conditions are established for three such methods to work and hard ware to implement these solutions is shown to be practicable. Each of the three proposed methods is seen to have advantages in certain circumstances - the choice between them depends very much on the nature of the graphics system in which they might be used
