Bent Normals and Cones in Screen-space
(The Eurographics Association, 2011)
Ambient occlusion (AO) is a popular technique for real-time as well as offline rendering. One of its benefits is a gain in efficiency due to the fact that occlusion and shading are decoupled which results in an average ...
Meshless Hierarchical Radiosity on the GPU
(The Eurographics Association, 2011)
Meshless radiosity is a radiosity method that is based on a point-based hierarchical discretization of the scene. This better decouples the runtime complexity from the geometric complexity of the scene and allows for an ...
Interactive Exploration of Polymer-Solvent Interactions
(The Eurographics Association, 2011)
The interaction of three-dimensional linked hydrophilic polymers with surrounding solvents in time-dependent data sets is of great interest for domain experts and current research in molecular dynamics. These polymers are ...
AFiT - Atrial Fibrillation Ablation Planning Tool
(The Eurographics Association, 2011)
The planning of cryo-balloon ablations for treatment of atrial fibrillation is a crucial task for a physician as he has to determine which size of the balloon catheter is required for isolation at each pulmonary vein. ...
Anatomy-Guided Multi-Level Exploration of Blood Flow in Cerebral Aneurysms
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
For cerebral aneurysms, the ostium, the area of inflow, is an important anatomic landmark, since it separates the pathological vessel deformation from the healthy parent vessel. A better understanding of the inflow ...
Real-Time Diffuse Global Illumination Using Radiance Hints
(ACM, 2011)
GPU-based interactive global illumination techniques are receiving an increasing interest from both the research and the industrial community as real-time graphics applications strive for vi-sually rich and realistic dynamic ...
Active Thread Compaction for GPU Path Tracing
(ACM, 2011)
Modern GPUs like NVidia s Fermi internally operate in a SIMD manner by ganging multiple (32) scalar threads together into SIMD warps; if a warp s threads diverge, the warp serially executes both branches, temporarily ...
SSLPV: Subsurface Light Propagation Volumes
(ACM, 2011)
This paper presents the Subsurface Light Propagation Volume (SSLPV) method for real-time approximation of subsurface scattering effects in dynamic scenes with changing mesh opology and lighting. SSLPV extends the Light ...
Improving SIMD Efficiency for Parallel Monte Carlo Light Transport on the GPU
(ACM, 2011)
Monte Carlo Light Transport algorithms such as Path Tracing (PT), Bi-Directional Path Tracing (BDPT) and Metropolis Light Transport (MLT) make use of random walks to sample light transport paths. When parallelizing these ...
Voxelized Shadow Volumes
(ACM, 2011)
Efficient shadowing algorithms have been sought for decades, but most shadow research focuses on quickly identifying shadows on surfaces. This paper introduces a novel algorithm to efficiently sample light visibility at ...
