چکیده

A new comprehensive reflectance model is presented. The model accounts for both surface and subsurface local light scattering. The model combines, for the first time, highly-efficient wave optics components and rigorous empirical components. The model displays a wide range of directional and non-directional light scattering phenomena and compares favorably against extensive, detailed reflectance measurements. The model is analytic and suitable for Computer Graphics applications. Benchmark timings are comparable with that of current less comprehensive models (Lafortune, Ward, and Cook-Torrance models). CR Categories: I.3.7 [Computer Graphics]: Three-Dimensional Graphics and Realism; I.3.3 [Computer Graphics]: Picture/Image Generation: I.6.4 [Model validation and analysis]

Numerical Investigation of Birefringene Effect on the Light Reflection

In the present paper, the problem of light reflection from a birefringent medium and thin film is considered. First, the analytical equations governing the propagation of a plane and harmonic electromagnetic wave in an infinite, birefringent, linear, non-dispersive, non-absorbing, and non-magnetic medium is derived from Maxwell equations. Then, using phase matching condition and boundary condit...

A Practical Framework for Virtual Viewing and Relighting

Recently many practical applications have concerned with observing objects that often have specula reflection properties. They intend to know how the specula reflections and details on the surface of objects vary according to different light conditions and view positions without calculating any 3D information of the objects. In this paper, we propose an innovative framework combining the novel ...
