Data, codes, and scripts underlying the PhD thesis: From Colors to Spectra and Back Again

A zipped collection of data, codes, and scripts applied in the PhD thesis "From Colors to Spectra and Back Again". We address several challenges in the context of spectral rendering, including efficient wavelength importance samping, color-to-spectrum uplifting, and artist-controllable color metamerism effects. Development of the thesis has resulted in C++/OpenGL implementations of spectral rendering and data analysis methods which are bundled in this dataset in accordance with each chapter in the thesis. We further include all test data, which is artificial (no physical data collection was performed). Test data is either spectral rendering scenes (chapters 2, 3, 4), or embedding data (appendix A).

本压缩数据集包含博士论文《From Colors to Spectra and Back Again》中所使用的全部数据、代码与脚本程序。本研究针对光谱渲染领域的多项核心挑战开展研究，涵盖高效波长重要性采样（wavelength importance sampling）、色彩到光谱提升（color-to-spectrum uplifting）以及艺术家可控的色彩同色异谱效应（artist-controllable color metamerism effects）三个方向。本论文的研发工作产出了光谱渲染与数据分析方法的C++/OpenGL实现代码，本数据集严格按照论文各章节的结构对这些代码进行了打包整合。此外，本数据集还包含全部测试数据，所有数据均为人工合成，未开展任何物理数据采集工作。测试数据分为两类：一类为第2、3、4章所用的光谱渲染场景数据，另一类为附录A中的嵌入数据。
