A Multi-Scale Physical Model Of Granular Materials
Granular material s display a certain number of properties that have long been observed but only partially understood. Some resemble the properties of solids, some resemble properties of fluids and others are unique. The concept of "fourth state of matter" has been mentioned. This is perhaps precisely the reason why these materials are so fascinating and beautiful. Thus the aim of this work is ...
متن کاملAn Inexpensive BRDF Model for Physically-Based Rendering
A new BRDF model is presented which can be viewed as an kind of intermediary model between empirism and theory. Main results of physics are observed (energy conservation, reciprocity rule, microfacet theory) and numerous phenomena involved in light reeection are accounted for, in a physically plausible way (incoherent and coherent reeection, spectrum modiications, anisotropy, self-shadowing, mu...
متن کاملNumerical solution of nonlinear SPDEs using a multi-scale method
In this paper we establish a new numerical method for solving a class of stochastic partial differential equations (SPDEs) based on B-splines wavelets. The method combines implicit collocation with the multi-scale method. Using the multi-scale method, SPDEs can be solved on a given subdomain with more accuracy and lower computational cost than the rest of the domain. The stability and c...
متن کاملComputation of polarized subsurface BRDF for rendering
Interest in polarization properties of the rendered materials is growing, but so far discussions on polarization have been restricted only to surface reflection, and the reflection due to subsurface scattering is assumed to be unpolarized. Findings from other field (e.g. optics and atmospheric science) show that volumetric interaction of light can contribute to polarization. So we investigated ...
