Computer graphics is a sub-field of computer science which studies methods for digitally synthesizing and manipulating visual content. Although the term often refers to the study of three-dimensional computer graphics, it also encompasses two-dimensional graphics and image processing.

History

The history of computer graphics can be traced back to the early 1950s, with the development of the first computers. Early work in the field was driven by the need for better visualization tools in scientific research and engineering. The invention of the framebuffer in the 1960s was a significant milestone, allowing for the storage and manipulation of images in memory.

Techniques

Computer graphics involves a variety of techniques and algorithms to create and manipulate images. Some of the key techniques include:

• Raster graphics: Representing images as a grid of pixels.
• Vector graphics: Using mathematical equations to represent images.
• Ray tracing: Simulating the way light interacts with objects to produce realistic images.
• Shading: Techniques to simulate the effects of light and shadow on surfaces.
• Texture mapping: Applying images to 3D models to add detail.

Applications

Computer graphics has a wide range of applications, including:

• Video games: Creating immersive and interactive environments.
• Movies: Producing special effects and animated films.
• Virtual reality: Simulating real-world environments for training and entertainment.
• Medical imaging: Visualizing complex data from medical scans.
• Scientific visualization: Helping researchers understand complex data sets.

Software

There are many software tools available for creating and manipulating computer graphics, including:

• Adobe Photoshop: A popular tool for raster graphics editing.
• Blender: An open-source tool for 3D modeling and animation.
• Autodesk Maya: A professional tool for 3D modeling, animation, and rendering.

Related Fields

Computer graphics is closely related to several other fields in computer science, including:

• Image processing: Techniques for enhancing and analyzing images.
• Computer vision: Enabling computers to interpret and understand visual information.
• Human–computer interaction: Designing user interfaces that are easy to use and understand.
