Scan Conversion(Circle) - Midpoint Algorithm

Assignment 05.
  1. Use the mid-point circle technique to derive the necessary equations to scan convert the following circular sector (i.e., points from 270o to 315o). 
  2. Implement your method and use the circle's symmetric property to draw complete circles.
  3.  
  4. The file is available here (ScanConvertCirclemidpoint.cpp)
  5. Play with it. You will understand..

    this code also correct!!
    void MidpointCircle(GLint x1, GLint y1, GLint x2, GLint y2){
    /********************************************************************
    This function draws a Circle using the Midpoint Circle algorithm for 270 - 315
    *********************************************************************/
    float r1 = (x2-x1)(x2-x1) + (y2-y1)(y2-y1);
    float r = sqrt(r1);
    int x=0,y=-r,p=1-r;
    while(x<=-y)
    {
    plot(x1+x,y1+y);

    if(p<0)
    {
    p=p+2*x+3;
    }
    else
    {

    p=p+2*(x+y)+5;
    y++;
    }
    x++;
    }

    }

Download your favorite Serials whole season at once

So, we all have our favorite serials. Or someone recently suggested you a serial which is now on it's latest season and you want to look at all those previous seasons. Some may watch it in online There are plenty of sites to watch them online. mywatchseries.to watch-series.com What if you want to download? You can download using IDM while playing online. How to download a whole season? Playing every episode and download? That's possible. But, is there an easy way? Yes. There is! These are the steps to follow. Before going down, download and install the latest IDM. IDM Latest (This is cracked. But, if you like. Support the developers by buying it) Step one Choose the site where you can download all your episodes. for example : http://dl2.mihanpix.com/Serial/ Index of Serial There are plenty of sites like this. To find those, just google "Index of Serials". Googled it Step two Go to the page of which season you want to download...

Scan Conversion(Line) - Bresenham's Algorithm

As the second Assignment we implemented Bresenham's Algorithm. For details visit  here . Assignment 02. 1.   Use the  Bresenham’s method to derive an algorithm to scan convert lines  with slope between 0 o  and -45 o (NOT  0 o  and +45 o ). 2.   Implement your algorithm to rasterize   lines that go from left to right, with slope between 0 o  and -45 o . 3.    Modify your program to scan convert lines with any slope. The file is available here (ScanConvertLine.cpp)
