Computer graphics is the field of creating and manipulating images using computers. It involves the creation, storage, and manipulation of images in digital form.
Key Characteristics / Core Concepts
- Raster Graphics: Images made of pixels (e.g., JPEGs, PNGs).
- Vector Graphics: Images made of mathematical equations (e.g., SVGs).
- 3D Modeling: Creating three-dimensional representations of objects.
- Rendering: Generating a 2D image from a 3D model.
- Animation: Creating the illusion of motion through a series of images.
How It Works / Its Function
Computer graphics relies on algorithms and software to process and display images. These algorithms manipulate pixels or mathematical data to create visual representations.
The process can involve various steps, from initial design and modeling to rendering and final output, depending on the complexity of the project.
Examples
- Video games
- Movies and television special effects
- Medical imaging (e.g., X-rays, CT scans)
Why is it Important? / Significance
Computer graphics is crucial in various industries, impacting fields like entertainment, medicine, engineering, and design. It enables visualization, simulation, and communication of complex information in a user-friendly way.
Its influence can be observed in daily life, from the images seen on smartphones and computers to complex simulations used for scientific research.
