Abstract

AbstractThe shadowing and masking of a rough surface is an important problem for reflection models in computer graphics. The widely used Smith’s geometry attenuation factor (GAF) takes a few factors such as root-mean-square (rms) into account and makes too many assumptions. In our research, we construct a brand-new calculation technique for issues involving light attenuation on a rough surface. The GAF algorithm is derived from a scattering field based on integral equations and the computational electromagnetic method. Specifically, our use of the method of moments has enabled us to tackle the problem of analytically computing the shadowing and masking on a rough surface by taking practical factors such as wavelength, surface contour, polarization, material, rms, and so on into consideration. It is more precise than Smith’s GAF theory.KEYWORDS: Light attenuationmicrofacet theorymasking and shadowingSmith’s theorythe method of momentscomputational electromagnetic method AcknowledgmentsThe authors would like to sincerely thank all reviewers for their helpful comments and suggestions.Disclosure statementNo potential conflict of interest was reported by the authors.Additional informationFundingThis work was supported by Natural Science Foundation of Shaanxi Province of China (2022JM-385).

基于积分方程的光衰减分析

摘要粗糙表面的阴影和遮挡是计算机图形学中反射模型的一个重要问题。广泛使用的Smith几何衰减因子(GAF)考虑了均方根(均方根)等少数因素，且假设过多。在我们的研究中，我们构建了一种全新的计算粗糙表面光衰减问题的技术。GAF算法是基于积分方程和计算电磁法从散射场中推导出来的。具体来说，我们使用矩量法，使我们能够通过考虑波长、表面轮廓、偏振、材料、均方根等实际因素，解决粗糙表面上阴影和遮蔽的解析计算问题。它比史密斯的GAF理论更精确。关键词:光衰减;微面理论;掩模与阴影;史密斯理论;矩量法;披露声明作者未报告潜在的利益冲突。项目资助:陕西省自然科学基金项目(2022JM-385)。

期刊介绍： The journal (under its former title Optica Acta) was founded in 1953 - some years before the advent of the laser - as an international journal of optics. Since then optical research has changed greatly; fresh areas of inquiry have been explored, different techniques have been employed and the range of application has greatly increased. The journal has continued to reflect these advances as part of its steadily widening scope. Journal of Modern Optics aims to publish original and timely contributions to optical knowledge from educational institutions, government establishments and industrial R&D groups world-wide. The whole field of classical and quantum optics is covered. Papers may deal with the applications of fundamentals of modern optics, considering both experimental and theoretical aspects of contemporary research. In addition to regular papers, there are topical and tutorial reviews, and special issues on highlighted areas. All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. General topics covered include: • Optical and photonic materials (inc. metamaterials) • Plasmonics and nanophotonics • Quantum optics (inc. quantum information) • Optical instrumentation and technology (inc. detectors, metrology, sensors, lasers) • Coherence, propagation, polarization and manipulation (classical optics) • Scattering and holography (diffractive optics) • Optical fibres and optical communications (inc. integrated optics, amplifiers) • Vision science and applications • Medical and biomedical optics • Nonlinear and ultrafast optics (inc. harmonic generation, multiphoton spectroscopy) • Imaging and Image processing
