Computer Graphics is the branch of computer science that deals with creating, manipulating, and displaying visual content using computers.

The overview of computer graphics process involve these 3:

  • Modeling, the process of representing 3D object or scene using mathematical models such as polygons, curves, or surfaces.
  • Rendering, generating 2D images from 3D object to be shown in computer screen. Rendering also simulate virtual environment such as lighting. Involves a combination of techniques such as ray tracing, rasterization, and shading.
  • Animation, manipulating movement and object in 3D models to produce illusion of life and action. This can be done with keyframe, motion capture, etc.
