An Inexpensive BDRF Model for Physically-Based Rendering
نویسنده
چکیده
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, multiple reeection, surface and subsurface reeection, diierences between homogeneous and heterogeneous materials). The model has been especially intended for computer graphics applications and therefore includes two main features : simplicity (a small number of intuitively understandable parameters controls the model) and eeciency (the formulation insures adequation to Monte-Carlo rendering techniques and/or hardware implementations).

متن کاملRadiative Transport Based Flame Volume Reconstruction from Videos.
We introduce a novel approach for flame volume reconstruction from videos using inexpensive charge-coupled device (CCD) consumer cameras. The approach includes an economical data capture technique using inexpensive CCD cameras. Leveraging the smear feature of the CCD chip, we present a technique for synchronizing CCD cameras while capturing flame videos from different views. Our reconstruction ...
متن کاملA Volumetric Approach to Physically-Based Rendering of Fabrics
Efficient physically accurate modeling and rendering of woven cloth at a yarn level is an inherently complicated task due to the underlying geometrical and optical complexity. In this paper, a novel and general approach to physically accurate cloth rendering is presented. By using a statistical volumetric model approximating the distribution of yarn fibers, a prohibitively costly explicit geome...
متن کاملRiver Flow Simulation Using SWAT Physically Based Model in Barandouzchay of Urmia Lake River Basin
Nowadays, there are too many models in the world for simulation of hydrological processes, such as the SWAT physically based model. The SWAT model is a continuous and physically based hydrologic model that is the smallest unit in this model is Hydrologic Response Unit, and all hydrological processes are simulated in each of these units. This model can simulate runoff, sedimentation, erosion and...
متن کاملPhysically Based Real-Time Translucency for Leaves
This paper presents a new shading model for real-time rendering of plant leaves that reproduces all important attributes of a leaf and allows for a large number of leaves to be shaded. In particular, we use a physically based model for accurate subsurface scattering on the translucent side of directly lit leaves. For real-time rendering of this model, we formulate it as an image convolution pro...
