Interactive Fibre Structure Visualization of the Heart
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The heart consists of densely packed muscle fibres. The orientation of these fibres can be acquired by using Diffusion Tensor Imaging (DTI) ex vivo. A good way to visualize the fibre structure in a cross section of the ... -
Fast Isosurface Rendering on a GPU by Cell Rasterization
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper presents a fast, high-quality, GPU-based isosurface rendering pipeline for implicit surfaces defined by a regular volumetric grid. GPUs are designed primarily for use with polygonal primitives, rather than volume ... -
Wipe-Off: An Intuitive Interface for Exploring Ultra-Large Multi-Spectral Data Sets for Cultural Heritage Diagnostics
(The Eurographics Association and Blackwell Publishing Ltd, 2009)A visual analytics technique for the intuitive, hands-on analysis of massive, multi-dimensional and multi-variate data is presented. This multi-touch-based technique introduces a set of metaphors such as wiping, scratching, ... -
GPU Rendering of Relief Mapped Conical Frusta
(The Eurographics Association and Blackwell Publishing Ltd, 2009)This paper proposes to use relief-mapped conical frusta (cones cut by planes) to skin skeletal objects. Based on this representation, current programmable graphics hardware can perform the rendering with only minimal ... -
Interactive Graphics for Computer Adaptive Testing
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Interactive graphics are commonly used in games and have been shown to be successful in attracting the general audience. Instead of computer games, animations, cartoons, and videos being used only for entertainment, there ... -
eNVyMyCar: A Multiplayer Car Racing Game for Teaching Computer Graphics
(The Eurographics Association and Blackwell Publishing Ltd, 2009)The development of a computer game is widely used as a way of conveying concepts regarding Computer Science. There are several reasons for this: it stimulates creativity, it provides an immediate sense of achievement (when ... -
High Dynamic Range Imaging and Low Dynamic Range Expansion for Generating HDR Content
(The Eurographics Association and Blackwell Publishing Ltd, 2009)In the last few years, researchers in the field of High Dynamic Range (HDR) Imaging have focused on providing tools for expanding Low Dynamic Range (LDR) content for the generation of HDR images due to the growing popularity ... -
Replica Exchange Light Transport
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We solve the light transport problem by introducing a novel unbiased Monte Carlo algorithm called replica exchange light transport, inspired by the replica exchange Monte Carlo method in the fields of computational physics ... -
A Bayesian Monte Carlo Approach to Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Most Monte Carlo rendering algorithms rely on importance sampling to reduce the variance of estimates. Importance sampling is efficient when the proposal sample distribution is well-suited to the form of the integrand but ... -
Fast Four-Way Parallel Radix Sorting on GPUs
(The Eurographics Association and Blackwell Publishing Ltd, 2009)Efficient sorting is a key requirement for many computer science algorithms. Acceleration of existing techniques as well as developing new sorting approaches is crucial for many real-time graphics scenarios, database ... -
Bounding Volume Hierarchies of Slab Cut Balls
(The Eurographics Association and Blackwell Publishing Ltd, 2009)We introduce a bounding volume hierarchy based on the Slab Cut Ball. This novel type of enclosing shape provides an attractive balance between tightness of fit, cost of overlap testing, and memory requirement. The hierarchy ...
