line drawing algorithm

Bresenham line drawing Algorithm is a Line Drawing Algorithm which calculates all intermediate points over the interval between start and end points, implemented with integer numbers and integer arithmetic such as addition, subtraction and avoids heavy operations like multiplication and division

Digital differential analyzer is a line drawing algorithm that is based on incremental method which calculates all intermediate points over the interval between start and end points. It uses the concept that rate of change in a straight line in constant and is a linear time complexity O(N) algorithm
