  • Descrição: This paper presents a new semantic and procedural level‐of‐detail (LoD) method applicable to any rule‐based procedural building definition. This new LoD system allows the customizable and flexible selection of the architectural assets to simplify, doing it in an efficient and artist‐transparent way. The method, based on an extension of traditional grammars, uses LoD‐oriented commands. A graph‐rewriting process introduces these new commands in the artist‐provided rule set, which allows to select different simplification criteria (distance, screen‐size projection, semantic selection or any arbitrary method) through a scripting interface, according to user needs. This way we define a flexible, customizable and efficient procedural LoD system, which generates buildings directly with the correct LoD for a given set of viewing and semantic conditions.
