Circle and Line Function in Computer Graphics

Hello Guys,
Circle Function:-
 Declaration: void circle(int x, int y, int radius);
Circle function is used to draw a circle with center (x,y) and third parameter specifies the radius of the circle. The code given below draws a circle.

C program for circle

#include<graphics.h>
#include<conio.h>
void main()
{
   int gd = DETECT, gm;
   initgraph(&gd, &gm, "C:\\TC\\BGI");
   circle(100, 100, 50);
 
   getch();
   closegraph();
   return 0;
}
In the above program (100, 100) are coordinates of center of the circle and 50 is the radius of circle.

Line Function:-

Line function is used to draw a line from a point(x1,y1) to point(x2,y2) i.e. (x1,y1) and (x2,y2) are end points of the line.The code given below draws a line.
Declaration: void line(int x1, int y1, int x2, int y2);

C programming code for line

#include <graphics.h>
#include <conio.h>
void main()
{
   int gd = 0, gm;
   initgraph(&gd, &gm, "C:\\TC\\BGI");
   line(100, 100, 200, 200);
   getch();
   closegraph();
   return 0;
}
Above program draws a line from (100, 100) to (200, 200).

Applications of Computer Graphics

Image
 Following applications of Computer Graphics are given below:- Computer Aided Design(CAD) Cartography Entertainment Animation & Simulation Education & Training Plotting 2D-3D curve Art & Commerce Morphing Communication Image Processing Medical Application i)Computer Aided Design(CAD):- The major use of Computer Graphics is in design process, particularly       for engineering & architectural system, but almost all products are now computer designed. CAD methods are now routinely use in the designing process buildings, automobiles, air crafts and many other products. ii) Cartography:- Computer Graphics are used to produce accurate and schematic representations of graphical and other natural phenomena from measured data. Example:-Geographic maps, Weather maps, population density maps, contour maps etc. iii)Animation :- Animation is rapid display of a sequence of images of 2D or 3D network position in order to create an illusion of movement. It is ...

Scan Conversion in Computer Graphics

Image
  Scan Conversion in Computer Graphics “When we represent regular objects in the form of discrete pixels, it is called Scan Conversion.”  Every graphics system must transform the primitives into a collection of pixels. The scan conversion is also called  “Rasterization.”  Each pixel in the graphical system has two states either  on  or  off . “The Scan Converting rate is a technique that is used in video processing. In this technique, we can change the horizontal and vertical frequency for many different purposes.”  We use a scan converter to perform scan conversions. We can define a line by its starting and ending points. On the other hand, we can define a circle by its radius, circle equation, and center point. Methods of Scan Conversion We can perform scan conversion by using two methods. Analog Method Digital Method Analog Method:  It is the best method for analog videos. A large number of delay cells perform the analog method. The Analog...

Components of Computer Graphics

Image
 Interactive Computer Graphics consist of three components such as:- i) Digital Memory Buffer(Frame Buffer) ii) T.V Monitor iii) Video (Display) Controller. i) Digital Memory Buffer :- This is the place where images or pictures are stored as an array (matrix of                                                         0 and 1, 0 represent darkness &1 represents images or pictures). Frame Buffer is the video RAM that is used to hold or map the images displayed on the screen. ii) T.V Monitor :-Monitor helps us to view the display and they make the use of CRT (Cathode Ray              Tube) iii) Display Controller :- It is an interface between the digital memory buffer and TV monitor. The main function of display controller is to pass the elements of framework to the monitor...
