vector graphics

Within the context of video games, the term vector graphics refers to generating the visuals procedurally, at runtime, by calling the graphical primitives provided by the rendering API straight from the game code. Historically, it used to mean graphics generated by directly controlling the electron beam of a cathode ray tube via custom circuitry; this was only feasible for arcade games and other specialized machines.

Either way, vector graphics are labor-intensive, CPU-intensive and best suited for abstract imagery. Rich color, particle systems and special effects based on transformations of the coordinate system are often employed to spice things up.

Several No Time To Play games are made with vector graphics: [[Square_Shooter?]], [[Buzz_Grid?]], RogueBot, Glittering Light and the original Laser Sky.
