Geometrically Exact Simulation of Inextensible Ribbon
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Narrow, inextensible, and naturally flat ribbons have some special and interesting phenomena under isometric deformations. Although a ribbon has a shape between rod and shell, directly applying the geometric representation ...
A Biophysically-Based Model of the Optical Properties of Skin Aging
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
This paper presents a time-varying, multi-layered biophysically-based model of the optical properties of human skin, suitable for simulating appearance changes due to aging. We have identified the key aspects that cause ...
Physically Meaningful Rendering using Tristimulus Colours
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In photorealistic image synthesis the radiative transfer equation is often not solved by simulating every wavelength of light, but instead by computing tristimulus transport, for instance using sRGB primaries as a basis. ...
