envyLight: An Interface for Editing Natural Illumination

An interactive interface for editing natural illumination that combines an algorithm to select environment-map regions, by sketching strokes on lighting features in the rendered image, with a small set of editing operations to quickly adjust the selected feature.

Toward Evaluating Material Design Interface Paradigms for Novice Users

This paper presents a user study that evaluated the relative benefits of different material-design interfaces, focusing on novice users' editing of the parameters of analytic bidirectional distribution functions (BRDFs) using three interface paradigms: physical sliders, perceptual sliders, and image navigation. The study analyzed two design tasks: precise adjustment and artistic exploration.

Interactive On-Surface Signal Deformation

An interactive system for artistic control over visual phenomena visible on surfaces. The method allows the user to intuitively reposition shadows, caustics, and indirect illumination using a simple click-and-drag user interface directly on the surfaces.

PantaRay: Fast Ray-Traced Occlusion Caching

This paper describes the architecture of a novel system for computation of sparse directional occlusion caches in massive scenes. The system has been used in the context of a fast cinematic lighting pipeline working in the spherical harmonics domain.
