dda algorithm
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.
dda algorithm
- 1.
- 2. • It isthe simplest & faster method . • Smooth line as compare to Direct Method. • Loss Of Information is less
- 3. • Floating pointarithmetic is still their in DDA algorithm.
- 5. Q1:In the 2ndStep 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) ? QUIZ(DDA)
