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, ... -
Interactive Editing of Lighting and Materials using a Bivariate BRDF Representation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a new Precomputed Radiance Transfer (PRT) algorithm based on a two dimensional representation of isotropic BRDFs. Our approach involves precomputing matrices that allow quickly mapping environment lighting, which ... -
Interactive Rendering of Non-Constant, Refractive Media Using the Ray Equations of Gradient-Index Optics
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Existing algorithms can efficiently render refractive objects of constant refractive index. For a medium with a continuously varying index of refraction, most algorithms use the ray equation of geometric optics to compute ... -
Interactive, Multiresolution Image-Space Rendering for Dynamic Area Lighting
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Area lights add tremendous realism, but rendering them interactively proves challenging. Integrating visibility is costly, even with current shadowing techniques, and existing methods frequently ignore illumination variations ... -
Invisible Seams
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Surface materials are commonly described by attributes stored in textures (for instance, color, normal, or displacement). Interpolation during texture lookup provides a continuous value field everywhere on the surface, ... -
A Layered Particle-Based Fluid Model for Real-Time Rendering of Water
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a physically based real-time water simulation and rendering method that brings volumetric foam to the real-time domain, significantly increasing the realism of dynamic fluids. We do this by combining a particle-based ... -
Multi-Image Based Photon Tracing for Interactive Global Illumination of Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Image space photon mapping has the advantage of simple implementation on GPU without pre-computation of complex acceleration structures. However, existing approaches use only a single image for tracing caustic photons, so ... -
A New Ward BRDF Model with Bounded Albedo
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Due to its realistic appearance, computational convenience, and efficient Monte Carlo sampling, Ward s anisotropic BRDF is widely used in computer graphics for modeling specular reflection. Incorporating the criticism that ... -
On Floating-Point Normal Vectors
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper we analyze normal vector representations. We derive the error of the most widely used representation, namely 3D floating-point normal vectors. Based on this analysis, we show that, in theory, the discretization ... -
On the Effective Dimension of Light Transport
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Light transport is often characterized within a high-dimensional space although practitioners have long known that it commonly behaves as a much lower-dimensional phenomenon. We study the effective dimension of light ... -
An Optimizing Compiler for Automatic Shader Bounding
(The Eurographics Association and Blackwell Publishing Ltd, 2010) -
Patch-based Texture Interpolation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we present a novel exemplar-based technique for the interpolation between two textures that combines patch-based and statistical approaches. Motivated by the notion of texture as a largely local phenomenon, ... -
A PCA Decomposition for Real-time BRDF Editing and Relighting with Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We propose a novel rendering method which supports interactive BRDF editing as well as relighting on a 3D scene. For interactive BRDF editing, we linearize an analytic BRDF model with basis BRDFs obtained from a principal ... -
Real-Time Concurrent Linked List Construction on the GPU
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We introduce a method to dynamically construct highly concurrent linked lists on modern graphics processors. Once constructed, these data structures can be used to implement a host of algorithms useful in creating complex ... -
SafeGI: Type Checking to Improve Correctness in Rendering System Implementation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Historically, rendering system development has been mainly focused on improving the numerical accuracy of the rendering algorithms and their runtime efficiency. In this paper, we propose a method to improve the correctness ... -
Semi-Stochastic Tilings for Example-Based Texture Synthesis
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We investigate semi-stochastic tilings based on Wang or corner tiles for the real-time synthesis of example-based textures. In particular, we propose two new tiling approaches: (1) to replace stochastic tilings with ... -
Sparsely Precomputing The Light Transport Matrix for Real-Time Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Precomputation-based methods have enabled real-time rendering with natural illumination, all-frequency shadows, and global illumination. However, a major bottleneck is the precomputation time, that can take hours to days. ... -
Spectralization: Reconstructing spectra from sparse data
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Traditional RGB reflectance and light data suffers from the problem of metamerism and is not suitable for rendering purposes where exact color reproduction under many different lighting conditions is needed. Nowadays many ... -
Two Methods for Fast Ray-Cast Ambient Occlusion
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Ambient occlusion has proven to be a useful tool for producing realistic images, both in offline rendering and interactive applications. In production rendering, ambient occlusion is typically computed by casting a large ... -
Visibility Editing For All-Frequency Shadow Design
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present an approach for editing shadows in all-frequency lighting environments. To support artistic control, we propose to decouple shadowing from lighting and focus on providing intuitive controls to edit the former. ...
