Measurement and Modeling of Microfacet Distribution Under Deformation

A model to simulate dynamic microfacet distribution for rough surfaces such as human skin that models the dynamic surface reflectance under deformation. For rendering, dynamic micro-geometries can be used to exhibits such effects.

A Fiber Scattering Model With Non-Separable Lobes

This talk shows how previous analytic fiber-reflectance models for rendering hair and fur lack important azimuthal variation of lobe widths and positions, and derives a new, practical non-separable fiber-reflectance model that exhibits these behaviors and compares closely to Monte Carlo ground truth.

Simulating Wind Effects on Cloth and Hair in Disney’s "Frozen"

Capturing the interaction of wind with cloth and hair in the wintry environment of "Frozen" was a challenge for the character-simulation team. The solution involved low-level simulation software changes, creation of custom fields and visualizers, and integration of windicator and wind-gust rigs into the shot production pipeline.
