The Use of Precomputed Triangle Clusters for Accelerated Ray Tracing in Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In this paper we present a hybrid algorithm for building the bounding volume hierarchy (BVH) that is used in accelerating ray tracing of animated models. This algorithm precomputes densely packed clusters of triangles on ...
Dart Throwing on Surfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In this paper we present dart throwing algorithms to generate maximal Poisson disk point sets directly on 3D surfaces. We optimize dart throwing by efficiently excluding areas of the domain that are already covered by ...

Deterministic Importance Sampling with Error Diffusion
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
This paper proposes a deterministic importance sampling algorithm that is based on the recognition that delta-sigma modulation is equivalent to importance sampling. We propose a generalization for delta-sigma modulation ...
Single Photo Estimation of Hair Appearance
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Significant progress has been made in high-quality hair rendering, but it remains difficult to choose parameter values that reproduce a given real hair appearance. In particular, for applications such as games where naive ...
Interactive Global Photon Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present a photon mapping technique capable of computing high quality global illumination at interactive frame rates. By extending the concept of photon differentials to efficiently handle diffuse reflections, we generate ...
Packet-based Hierarchal Soft Shadow Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
Recent soft shadow mapping techniques based on back-projection can render high quality soft shadows in real time. However, real time high quality rendering of large penumbrae is still challenging, especially when multilayer ...
Estimating Specular Roughness and Anisotropy from Second Order Spherical Gradient Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
This paper presents a novel method for estimating specular roughness and tangent vectors, per surface point, from polarized second order spherical gradient illumination patterns. We demonstrate that for isotropic BRDFs, ...
Texture Design and Draping in 2D Images
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
We present a complete system for designing and manipulating regular or near-regular textures in 2D images. We place emphasis on supporting creative workflows that produce artwork from scratch. As such, our system provides ...
Anomalous Dispersion in Predictive Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2009)
In coloured media, the index of refraction does not decrease monotonically with increasing wavelength, but behaves in a quite non-monotonical way. This behaviour is called anomalous dispersion and results from the fact ...
