Efficient Depth of Field Rasterization Using a Tile Test Based on Half-Space Culling
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
For depth of field (DOF) rasterization, it is often desired to have an efficient tile versus triangle test, which can conservatively compute which samples on the lens that need to execute the sample-in-triangle test. We ...
A Low-Memory, Straightforward and Fast Bilateral Filter Through Subsampling in Spatial Domain
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
In this work we present a new algorithm for accelerating the colour bilateral filter based on a subsampling strategy working in the spatial domain. The base idea is to use a suitable subset of samples of the entire kernel ...

Efficient Image-Based Proximity Queries with Object-Space Precision
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present an efficient algorithm for object-space proximity queries between multiple deformable triangular meshes. Our approach uses the rasterization capabilities of the GPU to produce an image-space representation of ...
Beyond Catmull–Clark? A Survey of Advances in Subdivision Surface Methods
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Subdivision surfaces allow smooth free‐form surface modelling without topological constraints. They have become a fundamental representation for smooth geometry, particularly in the animation and entertainment industries. ...
Interactive Ray Tracing of Large Models Using Voxel Hierarchies
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We propose an efficient approach for interactive visualization of massive models with CPU ray tracing. A voxel-based hierarchical level-of-detail (LOD) framework is employed to minimize rendering time and required system ...
Description and Solution of an Unreported Intrinsic Bias in Photon Mapping Density Estimation with Constant Kernel
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
This paper presents an analysis of the irradiance estimator often used in photon mapping algorithms and concludes that the classical approach with a constant kernel overestimates the correct value. We propose a new estimator ...
Exploring Different Parameters to Assess Left Ventricle Global and Regional Functional Analysis from Coronary CT Angiography
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Coronary CT angiography is widely used in clinical practice for the assessment of coronary artery disease. Several studies have shown that the same exam can also be used to assess left ventricle (LV) function. Even though ...
TreeMatrix: A Hybrid Visualization of Compound Graphs
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
We present a hybrid visualization technique for compound graphs (i.e. networks with a hierarchical clustering defined on the nodes) that combines the use of adjacency matrices, node-link and arc diagrams to show the graph, ...
Lazy Visibility Evaluation for Exact Soft Shadows
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
This paper presents a novel approach to compute high quality and noise‐free soft shadows using exact visibility computations. This work relies on a theoretical framework allowing to group lines according to the geometry ...
