3D graphics involves creating, processing, and visualizing models in three dimensions, often through techniques such as rendering and animation. It's used for everything from games and film to CAD, VR, and scientific visualization.

The magic of 3D graphics is built on creating geometric structures - models - that are defined by points, edges, and surfaces, and then illuminating them with virtual light sources, cameras, and shadows. The result can either be rendered to an image or presented in interactive real-time environments like games or VR apps.
