Real-time computer graphics

Real-time computer graphics are images and animations created by computers that update quickly and smoothly. It's like watching a movie, but with the action happening while you watch it. Instead of the computer having to think about what the next frame should look like and then showing an update, with real-time computer graphics the computer already knows what to show. This makes the graphics look more 'real' and move more smoothly.
