Non-symmetric Scattering in Light Transport Algorithms, is physically correct. For example, we show that non-symmetry occurs whenever light is refracted, and also whenever shading normals are used (e.g. due to interpolation of normals in a triangle mesh, or bump mapping [5])..We examine the implications of non-symmetric scattering for light transport th

Rendering Participating Media with Bidirectional Path Tracing,mage-based algorithm is computationally expensive but more versatile than previous solutions. It correctly handles multiple scattering in non-homogeneous, anisotropic media in complex illumination situations. We illustrate its specific advantages by means of examples.

Importance-driven Stochastic Ray Radiosity,ell-suited to compute the radiance distribution in very complex diffuse environments. In this paper we present an extension of this method which will provide a significant reduction of computational cost in cases where accurate knowledge of the illumination is needed in only a small part of the scen

Efficiently Representing the Radiosity Kernel through Learning,amples from the geometry definition and iteratively creates a functional model instantiated by a set of Gaussian basis functions. These are supported over the whole environment and thus, surfaces are not considered separately. Together with the implicit clustering algorithm provided by the applied l

Accurate Error Bounds for Multi-Resolution Visibility,or the efficient approximation of form factors in a controlled manner, with guaranteed error bounds at every stage of the calculation. In particular we discuss the issues of bounding the error in the form factor approximation using average cluster transmittance, combining subcluster calculations wit
