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 ... -
Decoupling Strokes and High-Level Attributes for Interactive Traditional Drawing
(The Eurographics Association, 2001)We present an interactive system, which allows the user to produce drawings in a variety of traditional styles. It takes as input an image and performs semi-automatic tonal modeling. Our system shifts tedious technical ... -
Shader Lamps: Animating Real Objects With Image-Based Illumination
(The Eurographics Association, 2001)We describe a new paradigm for three-dimensional computer graphics, using projectors to graphically animate physical objects in the real world. The idea is to replace a physical object with its inherent color, texture, ... -
Artistic Composition for Image Creation
(The Eurographics Association, 2001)Altering the viewing parameters of a 3D object results in computer graphics images of varying quality. One aspect of image quality is the composition of the image. While the esthetic properties of an image are subjective, ... -
Efficient Cloth Modeling and Rendering
(The Eurographics Association, 2001)Realistic modeling and high-performance rendering of cloth and clothing is a challenging problem. Often these materials are seen at distances where individual stitches and knits can be made out and need to be accounted ... -
Real-time, Photo-realistic, Physically Based Rendering of Fine Scale Human Skin Structure
(The Eurographics Association, 2001)Skin is noticeably bumpy in character, which is clearly visible in close-up shots in a film or game. Methods that rely on simple texture-mapping of faces lack such high frequency shape detail, which makes them look ... -
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 ... -
Simulating Non-Lambertian Phenomena Involving Linearly-Varying Luminaires
(The Eurographics Association, 2001)We present a new technique for exactly computing glossy reflections and transmissions of polygonal Lambertian luminaires with linearly-varying radiant exitance. To derive the underlying closed-form expressions, we introduce ... -
Reflected and Transmitted Irradiance from Area Sources using Vertex Tracing
(The Eurographics Association, 2001)Computing irradiance analytically from polygonal luminaires in polygonal environments has proven effective for direct lighting applications in diffuse radiosity environments. Methods for analytic integration have traditionally ... -
Thrifty Final Gather for Radiosity
(The Eurographics Association, 2001)Finite Element methods are well suited to the computation of the light distribution in mostly diffuse scenes, but the resulting mesh is often far from optimal to accurately represent illumination. Shadow boundaries are ... -
Lighting Design: A Goal Based Approach Using Optimisation
(The Eurographics Association, 1999)There is a need for reliable lighting design applications because available tools are limited and inappropriate for interactive or creative use. Architects and lighting designers need those applications to define, predict, ... -
Beyond Photorealism
(The Eurographics Association, 1999)For around 30 years the computer graphics research community has pursued photorealism as though it were the ultimate form of visual expression. Yet, as an art form, photorealism is one of many abstrations that an artist ... -
Effective Compression Techniques for Precomputed Visibility
(The Eurographics Association, 1999)In rendering large models, it is important to identify the small subset of primitives that is visible from a given viewpoint. One approach is to partition the viewpoint space into viewpoint cells, and then precompute a ... -
Interactive Virtual Relighting and Remodeling of Real Scenes
(The Eurographics Association, 1999)Lighting design is often tedious due to the required physical manipulation of real light sources and objects. As an alternative, we present an interactive system to virtually modify the lighting and geometry of scenes with ... -
Face Cluster Radiosity
(The Eurographics Association, 1999)An algorithm for simulating diffuse interreflection in complex three dimensional scenes is described. It combines techniques from hierarchical radiosity and multiresolution modelling. A new face clustering technique for ... -
Rendering Inhomogeneous Surfaces with Radiosity
(The Eurographics Association, 1999)Natural surfaces are often complex: they nearly always exhibit small scale imperfections such as dirt, dust, cracks, etc., as well as large scale structural elements, as for wickerwork, brick walls, textiles, pebbles, etc., ... -
Interactive Rendering with Arbitrary BRDFs using Separable Approximations
(The Eurographics Association, 1999)A separable decomposition of bidirectional reflectance distributions (BRDFs) is used to implement arbitrary reflectances from point sources on existing graphics hardware. Two-dimensional texture mapping and compositing ... -
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 ... -
Rendering of Wet Materials
(The Eurographics Association, 1999)The appearance of many natural materials is largely influenced by the environment in which they are situated. Capturing the effects of such environmental factors is essential for producing realistic synthetic images. In ... -
Space-Time Hierarchical Radiosity
(The Eurographics Association, 1999)This paper presents a new hierarchical simulation algorithm allowing the calculation of radiosity solutions for time-dependent scenes where all motion is known a priori. Such solutions could, for instance, be computed to ...
