Application of Computer Graphics

Computer graphics are visually representing data, information, or images with the help of computers. From video games to animated films, computer graphics have become an integral part of our daily lives. Understanding the different applications of computer graphics can help us appreciate how they make things like driving simulations, special effects in movies, architectural walkthroughs, and even something as simple as the user interface on our phones possible. This article will explore some of the major applications of computer graphics.


Hasonss | Applications/Function of Computer Graphics |

Some of the most common and essential functions and applications of computer graphics include:

User Interfaces: 

Almost every piece of modern digital technology relies on graphics for its user interface, including desktop/laptop computers, smartphones, GPS devices, etc. Interactive icons, menus, and visual elements allow intuitive interaction.

Digital Art:

Computer graphics tools empower artists to create stunning digital artwork using both raster (pixel) and vector graphics. Everything from concept art to matte paintings rely on such tools.

Photo/Video Editing:

Advanced editing suites like Photoshop or After Effects use graphics technology to enable editing images/footage in ways like applying filters, keying out backgrounds, compositing visual effects, color correction etc.

Data Visualization:

Conveying complex data visually using charts, graphs, diagrams, and infographics makes it easier to identify patterns and trends. Computer graphics help represent data visually.


Interactive graphics, simulations, animations and gaming elements are used to create engaging edutainment apps, e-learning tools, and educational videos tailored for the YouTube/social media age.

Scientific Visualization:

Transforming complex datasets into 3D models or representations makes it easier for researchers to understand and gain insights when analyzing the data.


Eye catching graphics in brochures, catalogs, packaging, advertising, social media, and websites are essential for brands to stand out and showcase products attractively to capture customer attention.


Dazzling computer graphics form the foundation for popular forms of entertainment like video games, theme park rides, animated shows/movies that transport audiences into immersive fictional worlds they can explore.


Realistic simulations of environments/scenarios are created using computer graphics to train personnel in aviation, space programs, medicine, military, architecture, disaster management without risks/costs of real-world training.

Hasons | Types of Application Software for Computer Graphics |

There are two broad categories of application software used for computer graphics:

1. Interactive Computer Graphics

These allow the user to interactively manipulate and control computer graphics in real-time. Some examples include:

  • Video Games: Modern video games use real-time 3D computer graphics to render lifelike environments and characters that players can interact with. Games range from simple 2D side scrollers to massive open world games with photorealistic graphics.
  • Driving/Flight Simulators: Simulators use interactive 3D graphics to create realistic driving or flying experiences for training purposes. The graphics allow the simulation of various conditions and scenarios.
  • CAD/CAM Software: CAD (computer-aided design) and CAM (computer-aided manufacturing) software uses interactive graphics to create and manipulate designs and models of products. Engineers can then test these virtual models digitally.
  • Virtual Reality: VR headsets use real-time computer graphics to immerse the user in a simulated 3D environment that they can interact with by moving and looking around. VR is used for gaming, training, visualization, and more.

2.Non-Interactive Computer Graphics

These produce graphics that cannot be manipulated in real-time. Some examples are:

  • CGI in Films/Animation: Computer generated imagery brings imaginary worlds and characters to life in movies and animated films. Graphics are pre-rendered by powerful computers without real-time user interaction.
  • Product Visualization: Photorealistic 3D renderings and animations of products are created to showcase product designs digitally with custom visuals instead of expensive physical samples.
  • Architectural Visualization: Detailed 3D models and walkthroughs of buildings/interiors are created to help architects pitch designs to clients without constructing expensive physical miniatures.
  • Special Effects: Visual effects like explosions, smoke, fire, etc that would be dangerous or expensive to produce physically are added to live action films using CGI.

Differences Between Application and System Software

To understand the role computer graphics plays, it helps to first distinguish between application and system software:

System Software consists of the programs that manage computer resources and provide a platform for users to install and run applications. For example, Windows, MacOS, Linux, Android and iOS are operating systems that handle technical functions in the background.

Application Software consists of user-facing programs designed for specific tasks that provide capabilities to users. Computer graphics is mostly used in application software to enable visual functions.


Some key differences:

Application Software System Software
Runs on platforms provided by system software Manages and integrates computer resources
User-facing with specific tasks Runs “under-the-hood”
Examples: Office suites, games, Photoshop Examples: Windows, Linux, Android
Uses computer graphics for UI and functionality Limited graphics, mostly text-based

While system software forms the foundation, application software utilizes the capabilities provided by the system to deliver domain-specific functionality. This is where computer graphics comes into play for the visual components.

Graphics capabilities were limited during the early era of computing. But over time with Moore’s Law driving rapid advances in processing power and specialized graphics hardware like GPUs, computer graphics have become integral to applications.

Real-World Applications of Computer Graphics

Beyond just entertainment and media, computer graphics have become vital for many critical real-world applications across different industries:


  • Surgical Simulation Systems
  • Interactive Patient Education
  • Medical Imaging Visualization
  • Virtual Reality Therapy
  • Augmented Reality Surgery
  • Digital Twin Modeling


  • CAD/CAM modeling
  • Engineering Analysis Simulations

  • Interactive User Manuals


  • Battlefield Simulators
  • Aircraft/Submarine Simulators
  • Mission Rehearsal Simulators
  • topographical Model Visualization
  • VR Training Simulations


  • Data Visualization and Dashboards
  • Interactive Sales Presentations

This small sampling illustrates just how integrated computer graphics have become across almost every technical field and profession because of how they simplify complex processes. Continuing advancement of graphics capabilities expands possibilities even further.


In closing, computer graphics clearly permeate numerous aspects of business, research, manufacturing, and entertainment thanks to the wealth of functions and applications they enable. Interactive graphics allow users to manipulate virtual objects in real-time, while pre-rendered imagery enlivens everything from movies to product design. And the expansive use cases across healthcare, engineering, science, and defense highlight the critical role graphics now play even in specialized industries dealing with complex visualizations. As hardware and software continue advancing hand-in-hand, computer graphics will become even more realistic and ubiquitous. So the next time you play a mobile game or FaceTime someone, take a moment to appreciate the graphics technology powering the visual experience.
