Our method contains two key components. First, we present a new c oncept of geometric predicates, called indirect offset predicates, to repr esent all intersection points through a new formulation and establish all necessary geometric predicates. Consequently, we reduce numerical errors i n floating-point evaluations and improve the success rate of early stages of arithmetic filtering. Second, we develop localization and dimension red uction techniques for sorting, deduplicating, and locating the intersectio n points, thereby boosting efficiency and parallelism while maintaining ac curacy. Rigorous testing confirms the robustness of our algorithm and cons istency with previous methods. Comprehensive testing across diverse datase ts further highlights the speed improvement achieved by our method, which is one order of magnitude faster than the state-of-the-art methods.\n\nReg istration Category: Full Access, Full Access Supporter\n\nLanguage Format: English Language\n\nSession Chair: Baoquan Chen (Peking University) URL:https://asia.siggraph.org/2024/program/?id=papers_451&sess=sess103 END:VEVENT END:VCALENDAR
