Discrete arcs and curves

Lebiedź J.

Machine Graphics and Vision

2000

Vol. 9, No. 1/2

25-30

The paper presents a new proposition of definitions of the discrete arc and the discrete curve. The proposed definitions are based on the neighborhood patterns.

Integer midpoint Bezier curve scan-conversion algorithm

Lebiedź J.

Machine Graphics and Vision

1998

Vol. 7, No. 1/2

407-415

By much the same midpoint methodology as is employed in algorithms which generate a quantized representation of a straight line or a circle, incremential algorithms using only integer operations ( addition/subtraction and sign testing) can generate a close approximation of more complicated curves given by implicit equation F(x, y)= 0 for parabolic and cubic Bezier curves are derived and integer midpoint algorithms for these curves are presented.
