Spectral rendering has received increasing attention in recent years. Yet, solutions to define spectral reflectances are mostly limited to uplifting techniques which deterministically augment existing RGB inputs. Only recently has uplifting been able to ensure a certain surface a

Spectral Uplifting via Controllable Color Constraints
Spectral rendering is a crucial solution for photorealistic rendering. However, most available texture assets are RGB-only, and access to spectral content is limited. Uplifting methods that recover full spectral representations from RGB inputs have therefore received much attenti

t-distributed Stochastic Neighbour Embedding (t-SNE) has become a standard for exploratory data analysis, as it is capable of revealing clusters even in complex data while requiring minimal user input. While its run-time complexity limited it to small datasets in the past, recent

Spectral Monte Carlo rendering can simulate advanced light phenomena, such as chromatic dispersion, but typically shows a slow convergence behavior. Properly sampling the spectral domain can be challenging in scenes with many complex spectral distributions. To this end, we propos
