pregenerated

Pregenerated refers to objects, data, or content that are created before they are needed, rather than being produced on demand at the time of use. The term is used across computing, digital media, testing, and simulation to denote a separation between generation and consumption. Pregenerated content can include textures, models, audio clips, datasets, or entire scenario layouts that are shipped with software or prepared offline for later loading.

In computing and software, pregeneration is often used to reduce runtime latency, enable offline workflows, or improve reproducibility by providing a fixed set of results or assets. For example, a game might ship with pregenerated maps and assets so loading times are shorter, while a data-analysis pipeline may rely on pregenerated datasets to ensure consistent test conditions.

In simulations and procedural generation, pregenerated elements allow for deterministic experiences across devices or sessions. A user can share a world snapshot or replays built from a predefined collection of assets. In testing, pregenerated inputs or responses support repeatable, controlled experiments and easier regression checks.

In digital media, pregenerated content can serve as starter packs or templates, enabling artists and developers to begin work quickly or to provide ready-made experiences for users. However, pregeneration involves storage costs and the risk of content becoming stale or outdated, and it may reduce dynamic responsiveness if updates are not synchronized with the consuming system.

Related concepts include precomputation and caching, which describe similar ideas in different contexts but emphasize different aspects of generation timing and storage.
