PIXEL FUNCTIONS IN COMPUTER GRAPHICS

Abstract

The paper presents a set of curve drawing algorithms with the corresponding theoretical background based on a "discreet analysis". The proposed algorithms for drawing plane curves use integer addition onely. The set of algorithms constitutes a homogeneous system comprising straight lines, different kinds of polinomiaJs (including all conic sections), exponentials, hyper- bolic and trigonometric functions, etc. and represents a new viewpoint for classification of curves. The paper points out the possibilities of generalization for 3D curves and surfaces as well as the prospects of practical application ill the different fields of computational geometry. CAD, robotics, etc.
