Gloss-Bridge: A Method to Reduce the Visual Perception Gap between Real-World Glossiness and PBR Reflectance Properties in Virtual Reality

With the rapid development of virtual reality (VR) technology, digital materials have become more realistic and controllable, offering new opportunities for material perception research. However, parameters physically based rendering (PBR), which are widely used in industry, often derived from design experience lack interpretability. This study aims to investigate visual difference glossiness between real environments. A compensation method is proposed bridge gap real-world PBR. Two psychophysical experiments conducted. Experiment 1 measures psychological with different world VR using a two-alternative forced-choice (2AFC) design. 2 establishes connection multiple PBR psychologically perceived obtained through matching adjustment experiment. Finally, mapping real-time rendering, Gloss-Bridge, introduced. maps physical quantity (measured by gloss meter) various parameters. By instead empirical parameters, it eliminates tedious hyper-parameter adjustments. achievement provides basis production on subjective
