This paper presents a novel hybrid neural-wavelet Precomputed Radiance Transfer (PRT) solution for real-time rendering of complex light transport effects such as glossy global illumination. The authors leverage modern multi-layer perceptron (MLP)-based function approximators and recent rendering advances to tackle the challenges of high-frequency indirect illumination, including glossy reflection, for relighting with changing view. The proposed method demonstrates real-time precomputed rendering of challenging scenes involving view-dependent reflections and even caustics.
