摘要光与材料的相互作用是基于物理的真实感绘制的关键。然而,分析起来也很复杂,尤其是当材料包含大量细节从而表现出“闪闪发光”的视觉效果时。最近的方法,生产闪亮的外观,预计将是重要的下一代计算机图形。我们在这里提供了一个全面的调查最近闪闪发光的外观渲染。本文首先基于微刻面理论对闪烁外观进行了定义,然后从表示和实际绘制两个方面对闪烁外观的研究工作进行了总结。我们已经实现了典型的方法,使用我们的统一平台,并比较他们在视觉效果,渲染速度和内存消耗。最后,我们简要讨论了局限性和未来的研究方向。我们希望我们的分析,实现和比较将为希望选择合适的应用方法或进行研究的读者提供见解。
Abstract The interaction between light and materials is key to physically-based realistic rendering. However, it is also complex to analyze, especially when the materials contain a large number of details and thus exhibit “glinty” visual effects. Recent methods of producing glinty appearance are expected to be important in next-generation computer graphics. We provide here a comprehensive survey on recent glinty appearance rendering. We start with a definition of glinty appearance based on microfacet theory, and then summarize research works in terms of representation and practical rendering. We have implemented typical methods using our unified platform and compare them in terms of visual effects, rendering speed, and memory consumption. Finally, we briefly discuss limitations and future research directions. We hope our analysis, implementations, and comparisons will provide insight for readers hoping to choose suitable methods for applications, or carry out research.
