Introduction to Computer Graphics
Computer graphics is a field of study and practice that focuses on creating, manipulating, and displaying visual content using computer system. It involves utilise of algorithms, mathematical formulas, and programming techniques to make and render images, interactive graphics, and animations.
Computer graphics applications are going to use in many areas, including design (architectural visualization, product design), entertainment (video games, movies, virtual reality), simulation (flight simulators, weather modeling), scientific research, and data visualization.
It encompasses both raster graphics, composed of pixels, and vector graphics, defined by mathematical equations. Computer graphics plays a crucial role in enhancing user experiences, communicating information visually, and enabling creative expression.
What are the Different Types of Computer Graphics?
In this section, we will explore the world of computer graphics! And you will learn about different types of computer graphics; how they can be used to create stunning visuals. Computer graphics can be broadly categorized into two main types as following them:
Raster graphics is also known as bitmap graphics, are digital images composed of a grid of individual pixels. Each pixel carries specific color and brightness information, allowing for detailed rendering of visuals.
Raster graphics store information about each pixel’s color and position, making them ideal for representing complex and detailed imagery such as photographs and digital paintings. However, resizing or scaling raster graphics can result in loss of quality due to pixelation.
Common file formats for raster graphics include JPEG, PNG, and GIF. They are widely used in digital photography, web design and various multimedia applications.
Raster Graphics Examples:
- Digital Paintings

- Scanned Documents
- Comic Books and Manga
- User Interface (UI) Design
- Advertising Materials (posters, flyers, billboards)
File Formats for Raster:
- JPEG (Joint Photographic Experts Group)
- PNG (Portable Network Graphics)
- GIF (Graphics Interchange Format)
- TIFF (Tagged Image File Format)
- BMP (Bitmap)
- PSD (Photoshop Document)

Disadvantages of Vector Graphics:
- Difficulty in representing complex and realistic textures and shading
- Limited suitability for representing highly detailed or photographic imagery
- Inability to achieve the same level of visual richness and depth as raster graphics
- Limited range of color options and effects compared to raster graphics
- Complexity in creating organic or freehand shapes that require intricate detailing
- Processing limitations in rendering complex vector graphics in real-time
- Lack of compatibility with certain software or platforms that primarily support raster graphics
- Challenges in accurately representing certain natural phenomena, such as natural gradients or irregular patterns
- Increased complexity in handling and editing complex vector files compared to raster images
- Difficulty in creating realistic, non-linear or dynamic animations compared to raster-based animations
Differences in Between Raster and Vector Graphics
Here are 10 differences between raster and vector graphics presented in tabular form:
