Computer graphics an introduction | Razsoft education


Computer graphics or CG

Definition:

  • Computer graphics is a field of computer science in which we study the creation and manipulation of images. 

  • Computer graphics is an art of communicating to computer visually.

Application:

  • Movies: - In movies they use VFX to create many scene like large explosion, plane crash or create entirely new environment like in Avengers and avatar.
  • Cartoons: - It’s used to create fictional characters and animate them to make animation videos like Doremon, Tom and Jerry and Motu-Patlu.  
  • Video games: - Video game is industry completely based on computer graphics. It’s used to create environment, character and interaction with them. Some popular computer games are like Vice city, Temple run, PUBG, etc.
  • Simulation: - Using computer we can describe behavior of object’s in computer then simulate them in virtual environment to see the effect. It’s also used to teach people about complex machine operation like plane or train.
  • Data visualization: - Business uses computer graphics to see it’s various type of data like sales and customer report in graph and chart format to easily understand it.
  • Virtual Reality: - Using VR we can interact with virtual environment using VR sets.
  • CAM/CAD: - Creating a model of products in side computer using CAD tools to see how it look and make changes inside it also checks how it get affected in different environment. Also using CAM tools we can fabricate it to automate manufacturing.

Types of computer graphics

  • Vector graphics: - It’s a method in which images are stored as a mathematical formula. These images don’t have resolution.
  • Raster Graphics: - In this method images are stored as a grid/array of pixel and each pixel. The image has pre-defined resolution and images get pixilated after some point.

Basic element of computer graphics

  • Modeling: - Defining object in mathematically inside computer.
  • Rendering: - Converting objects into pictorial form.
  • Animation: - Showing the evolution of objects over the period of time.

"climits" Header file in c++ programming language | Razsoft Education

 <climits> header file climits is a header file borrowed from c programing language limit.h header file. The header file is used to know the maximum and minimum value an integer data type can hold. The header file is implemented in C++ in standard namespace.  Here is the explanation of Macros used in climits header file char type :     CHAR_BIT - The macro represent number of bit in a  character.     CHAR_MIN -  For the minimum value a char can hold.      CHAR_MAX -  For the maximum value a char can hold.        CHAR_MIN -  For the minimum value a char can hold.     S CHAR_MIN -  For the minimum value a signed char can hold.     S CHAR_MAX -  For the maximum value a char can hold.     UCHAR_MAX - For the minimum value of unsigned char. short type :     SHRT_MIN - For the minimum value a short can hold.      SHRT_MAX - For the maximum value a short integer can hold.     U SHRT_MIN - For the maximum value a unsigned short integer can hold. int type :     INT _MIN - For the minimum

Integer data type in C++ programming language | Razsoft education

 Integer data type in C++ Integers are numbers with no fractional part. In C++ we represent integers in various type according to how big value they can store or what type of integer value they can store. All integer types has signed and unsigned type in C++. Signed type integer can store both positive and negative integer values. Unsigned type integer can store only positive values.

Accessing device coordinates in java graphics | Razsoft Education

 Java 2D API defines three level of configuration information to encapsulate conversion information from user to device coordinate. 1. Graphics Environment class :- GraphicsEnvironment class describe the collection of rendering device visible to the java application on a platform. Rendering device include screens, printers and image buffers. It also include all the fonts available to the device.  2. Graphics Device class :- GraphicsDevice class describe all the possible rendering device on the graphics environment. Such as screens or printers. 3. Graphics Configuration class :- A GraphicsConfiguration class contains all the different types of configuration supported by the graphics device. For example let a screen may have two different configuration such as 720 * 480 or 1920 * 1080 pixel resolution. We can change it's configuration as we want. Or a screen may have different color mode such as 16-bit, 32 - bit or 256 bit color mode. All such information about a device is stored in

               Graphics is a way to represent visual element in application. Java provided us rich set of methods and class through Java2D API to deal with the graphics in java platform and application. Using AWT methods to draw and manipulated GUI interface.                Java2D comes with rich set of function to manipulate images, text, font, color, etc. It has capability to draw basic geometric shapes and curves. Java media framework allows us to work with media files and create animations. Java media framework depends upon Java2D framework for rendering purposes.                For basic drawing operation every java AWT component which is visible to screen contains a reference to graphics object, which is an object of abstract class Graphics. It comes with many useful methods to draw elements like rectangle, ellipses and lines on AWT components. To use this method we just need to override paint() method of AWT component.                In this example we are going to
