Hi,
I am trying solve an example of Midpoint Circle algorithm which is in a book. I have also found this example at:
web2.aabu.edu.jo/tool/course_file/lec_notes/901350_S03.ppt‎

I not able to calculate the value of 2Yk+1. In the above link at slide 40, its value is 20 for radius = 10. However in my view its value should be 18. The formula for :

2YK+1= 2YK -2

is given on slide 36. Plz guide me.

Zulfi.

 

Your link doesn't work.

 

I second the bad link.

You might look at the Wikipedia article:

Hi,
I actually accessed it through google. Just now i tried to search:

901350_S03.ppt

& it showed me the link with the name

[PPT]View
web2.aabu.edu.jo/tool/course_file/lec_notes/901350_S03.ppt‎
1. COMPUTER GRAPHICS. CHAPTER 3. 2D GRAPHICS ALGORITHMS. 2. 2D Graphics Algorithms. Output Primitives; Line Drawing Algorithms. DDA Algorithm ...

In the meantime, i would check the link provided by yourself.
Thanks for your interest in my problem. Kindly guide me.
Zulfi.

 

Hi,
Thanks. I checked the link. It does not contain the example. I am trying to solve an example. I have checked another link which shows the algorithm on slide # 43:ae.sharif.edu/~aerocad/Output%20primitives.ppt.
I have also uploaded the images of the slides which i discussed earlier.

In the example, radius (r=10).
