Multiple Axis-Aligned Filters for Rendering of Combined Distribution Effects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Distribution effects such as diffuse global illumination, soft shadows and depth of field, are most accurately rendered using Monte Carlo ray or path tracing. However, physically accurate algorithms can take hours to ...
Practical Path Guiding for Efficient Light-transport Simulation
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a robust, unbiased technique for intelligent light-path construction in path-tracing algorithms. Inspired by existing path-guiding algorithms, our method learns an approximate representation of the scene's ...
From Faces to Outdoor Light Probes
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Image-based lighting has allowed the creation of photo-realistic computer-generated content. However, it requires the accurate capture of the illumination conditions, a task neither easy nor intuitive, especially to the ...
Parallel Reinsertion for Bounding Volume Hierarchy Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We present a novel highly parallel method for optimizing bounding volume hierarchies (BVH) targeting contemporary GPU architectures. The core of our method is based on the insertion-based BVH optimization that is known to ...
Explorative Blood Flow Visualization using Dynamic Line Filtering based on Surface Features
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Rupture risk assessment is a key to devise patient-specific treatment plans of cerebral aneurysms. To understand and predict the development of aneurysms and other vascular diseases over time, both hemodynamic flow patterns ...
An Explicit Structure-preserving Numerical Scheme for EPDiff
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
We present a new structure-preserving numerical scheme for solving the Euler-Poincaré Differential (EPDiff) equation on arbitrary triangle meshes. Unlike existing techniques, our method solves the difficult non-linear ...
Spatial Matching of Animated Meshes
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
This paper presents a new technique which makes use of deformation and motion properties between animated meshes for finding their spatial correspondences. Given a pair of animated meshes exhibiting a semantically similar ...
Topology Aware Data-Driven Inverse Kinematics
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Creating realistic human movement is a time consuming and labour intensive task. The major difficulty is that the user has to edit individual joints while maintaining an overall realistic and collision free posture. Previous ...
Synthesizing Two-character Interactions by Merging Captured Interaction Samples with their Spacetime Relationships
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Existing synthesis methods for closely interacting virtual characters relied on user-specified constraints such as the reaching positions and the distance between body parts. In this paper, we present a novel method for ...
Robust Image Denoising Using a Virtual Flash Image for Monte Carlo Ray Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We propose an efficient and robust image-space denoising method for noisy images generated by Monte Carlo ray tracing methods. Our method is based on two new concepts: virtual flash images and homogeneous pixels. Inspired ...
