Real-Time Level-of-Detail rendering with ReSTIR

Year: 2026

Type: conference-paper

Abstract: Rendering complex scenes in real time remains challenging due to strict performance constraints. Geometric level of detail (LoD) is widely used to reduce cost by replacing high-frequency geometry with prefiltered representations. ReSTIR significantly improves real-time rendering quality by reusing samples across space and time; however, its effectiveness degrades in the presence of complex geometry, where high-frequency detail reduces reuse efficiency. Moreover, prior ReSTIR methods require the same mesh topology across frames, causing sample reuse to break when switching LoD.
