A Compact Example-Driven Procedural Model for Efficient Glint Appearance Synthesis in Real-Time
Keywords:
Glint appearance, procedural shading, real-time rendering, microfacet modelingAbstract
The realistic rendering of highly detailed and complex surface appearances, particularly those exhibiting intricate specular highlights known as glints, poses significant challenges for real-time graphics. Traditional Bidirectional Reflectance Distribution Functions (BRDFs) often fall short in capturing the fine-scale microgeometry responsible for these effects. This paper presents a novel, compact example-driven procedural model designed to generate and render glinty appearances efficiently in real-time. By leveraging a concise set of pre-computed or pre-analyzed examples, our procedural framework synthesizes plausible micro-surface details on-the-fly, enabling dynamic and visually compelling glint patterns without requiring extensive storage or complex pre-filtering. We demonstrate that this approach offers a compelling balance between visual fidelity, computational efficiency, and memory footprint, making it suitable for interactive applications and games.
