Questions tagged [procedural]
Information that is generated by an algorithm/procedure. This is often used in contrast to recorded information. Examples are sounds that are generated by the oscillators of a synthesizer in contrast to sounds recorded by a sampler and just played back, and an image generated by a noise algorithm in a 3D-program in contrast to a digital photograph of clouds.
