This document discusses the digital differential analyzer (DDA) algorithm for computer graphics. It notes that DDA is a simpler and faster method than the direct method, with a smoother line and less loss of information. While floating point arithmetic is still used in DDA, the value of m does not need to be explicitly calculated if m is less than 1. The document also contains questions about calculating values for the DDA algorithm.

1. DG kaur

2. • It is the simplest & faster method .
• Smooth line as compare to
Direct Method.
• Loss Of Information is less

3. • Floating point arithmetic is still
their in DDA algorithm.

5. Q1:In the 2nd Step we have to calculate the value of b?
Q2: Does Not Metter the value of m is calculated or not.
Q3: If (m<1), I will assume y ?
Q4: for calculating m
= (m=x2-x1/y2-y1) ?
