iCheat: A Representation for Artistic Control of Indirect Cinematic Lighting
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Thanks to an increase in rendering efficiency, indirect illumination has recently begun to be integrated in cinematic lighting design, an application where physical accuracy is less important than careful control of scene ... -
An Illumination Model for a Skin Layer Bounded by Rough Surfaces
(The Eurographics Association, 2001)In this paper we present a novel illumination model that takes into account multiple anisotropic scattering in a layer bounded by two rough surfaces. We compute the model by a discrete-ordinate solution of the equation of ... -
An Illumination Model for a System of Isotropic Substrate- Isotropic Thin Film with Identical Rough Boundaries
(The Eurographics Association, 1999)A new physically-based illumination model describing the interaction of light with a system composed of an isotropic substrate coated by an isotropic film with geometrically identical statistical rough boundaries (ITF) is ... -
Illumination-driven Mesh Reduction for Accelerating Light Transport Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2015)Progressive light transport simulations aspire a physically-based, consistent rendering to obtain visually appealing illumination effects, depth and realism. Thereby, the handling of large scenes is a difficult problem, ... -
An Image-Based Approach for Stochastic Volumetric and Procedural Details
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Noisy volumetric details like clouds, grounds, plaster, bark, roughcast, etc. are frequently encountered in nature and bring an important contribution to the realism of outdoor scenes. We introduce a new interactive approach, ... -
Image-Based BRDF Measurement Including Human Skin
(The Eurographics Association, 1999)We present a new image-based process for measuring the bidirectional reflectance of homogeneous surfaces rapidly, completely, and accurately. For simple sample shapes (spheres and cylinders) the method requires only a ... -
Image-based Environment Matting
(The Eurographics Association, 2002)Environment matting is a powerful technique for modeling the complex light-transport properties of real-world optically active elements: transparent, refractive and reflective objects. Recent research has shown how environment ... -
Image-Based Reconstruction of Spatially Varying Materials
(The Eurographics Association, 2001)The measurement of accurate material properties is an important step towards photorealistic rendering. Many real-world objects are composed of a number of materials that often show subtle changes even within a single ... -
Image-Based Stereoscopic Painterly Rendering
(The Eurographics Association, 2004)We present a new image-based stereoscopic painterly algorithm that we use to automatically generate stereoscopic paintings. Our work is motivated by contemporary painters who have explored the aesthetic implications of ... -
Image-driven Navigation of Analytical BRDF Models
(The Eurographics Association, 2006)Specifying parameters of analytic BRDF models is a difficult task as these parameters are often not intuitive for artists and their effect on appearance can be non-uniform. Ideally, a given step in the parameter space ... -
Importance Point Projection for GPU-based Final Gathering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a practical importance-driven method for GPU-based final gathering. We take as input a point cloud representing directly illuminated scene geometry; we then project and splat the points to microbuffers, which ... -
Importance Resampling for Global Illumination
(The Eurographics Association, 2005)This paper develops importance resampling into a variance reduction technique for Monte Carlo integration. Importance resampling is a sample generation technique that can be used to generate more equally weighted samples ... -
Importance Sampling Microfacet-Based BSDFs using the Distribution of Visible Normals
(The Eurographics Association and John Wiley and Sons Ltd., 2014)We present a new approach to microfacet-based BSDF importance sampling. Previously proposed sampling schemes for popular analytic BSDFs typically begin by choosing a microfacet normal at random in a way that is independent ... -
Importance Sampling Techniques for Path Tracing in Participating Media
(The Eurographics Association and Blackwell Publishing Ltd., 2012)We introduce a set of robust importance sampling techniques which allow efficient calculation of direct and indirect lighting from arbitrary light sources in both homogeneous and heterogeneous media. We show how to distribute ... -
Improved Half Vector Space Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2015)In this paper, we present improvements to half vector space light transport (HSLT) [KHD14], which make this approach more practical, robust for difficult input geometry, and faster. Our first contribution is the computation ... -
Improved Stochastic Progressive Photon Mapping with Metropolis Sampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents an improvement to the stochastic progressive photon mapping (SPPM), a method for robustly simulating complex global illumination with distributed ray tracing effects. Normally, similar to photon mapping ... -
Incremental Instant Radiosity for Real-Time Indirect Illumination
(The Eurographics Association, 2007)We present a method for rendering single-bounce indirect illumination in real time on currently available graphics hardware. The method is based on the instant radiosity algorithm, where virtual point lights (VPLs) are ... -
Inferring Reflectance Functions from Wavelet Noise
(The Eurographics Association, 2005)This paper presents a novel method for acquiring a wavelet representation of the reflectance field of real objects. Key to our method is the use of wavelet noise illumination to infer a reflectance function for each pixel. ... -
Information Theory Tools for Scene Discretization
(The Eurographics Association, 1999)Finding an optimal discretization of a scene is an important but difficult problem in radiosity. The efficiency of hierarchical radiosity for instance, depends entirely on the subdivision criterion and strategy that is ... -
Instant Ray Tracing: The Bounding Interval Hierarchy
(The Eurographics Association, 2006)We introduce a new ray tracing algorithm that exploits the best of previous methods: Similar to bounding volume hierarchies the memory of the acceleration data structure is linear in the number of objects to be ray traced ...
