Physically accurate rendering often calls for taking the wave nature of light into consideration.
In computer graphics, this is done almost exclusively locally, ie on a micrometre scale …

Tremendous effort has been extended by the computer graphics community to advance the
level of realism of material appearance reproduction by incorporating increasingly more …

Optical phenomena that are only observable in optically anisotropic materials are generally
ignored in the computer graphics. However, such optical effects are not restricted to exotic …

We present a novel method for devising a closed-form analytic expression to the light
transport through the bulk of inhomogeneous optically anisotropic media. Those optically …

Ray optics is the foundation of modern path tracing and sampling algorithms for computer
graphics; crucially, it allows high-performance implementations based on ray tracing. However…

Under ray-optical light transport, the classical ray serves as a linear and local "point query"
of light's behaviour. Linearity and locality are crucial to the formulation of sophisticated path …

Free-space diffractions are an optical phenomenon where light appears to "bend" around the
geometric edges and corners of scene objects. In this paper we present an efficient method …

Our purpose in this paper is two-fold: introduce a computationally-tractable decomposition
of the coherence properties of light; and, present a general-purpose light-matter interaction …

Under the ray picture of light, light consists of “luminous” corpuscles. As such a particle
evolves by propagating and interacting with optical systems, it traces a “light ray”. A particle’s …
