Page "Quake III Arena" Paragraph 14

The graphic technology of the game is based tightly around a " shader " system where the appearance of many surfaces can be defined in text files referred to as " shader scripts.

" Quake 3 also introduced spline-based curved surfaces in addition to planar volumes, which are responsible for many of the surfaces present within the game.

Quake 3 also provided support for models animated using vertex animation with attachment tags ( known as the. md3 format ), allowing models to maintain separate torso and leg animations and hold weapons.

Quake 3 is one of the first games where the third-person model is able to look up and down and around as the head, torso and legs are separate.

Other visual features include volumetric fog, mirrors, portals, decals, and wave-form vertex distortion.
