A Physically Consistent Implicit Viscosity Solver for SPH Fluids
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we present a novel physically consistent implicit solver for the simulation of highly viscous fluids using the Smoothed Particle Hydrodynamics (SPH) formalism. Our method is the result of a theoretical and ... -
Repairing Inconsistent Curve Networks on Non-parallel Cross-sections
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this work we present the first algorithm for restoring consistency between curve networks on non-parallel cross-sections. Our method addresses a critical but overlooked challenge in the reconstruction process from ... -
PointProNets: Consolidation of Point Clouds with Convolutional Neural Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)With the widespread use of 3D acquisition devices, there is an increasing need of consolidating captured noisy and sparse point cloud data for accurate representation of the underlying structures. There are numerous ... -
Wavejets: A Local Frequency Framework for Shape Details Amplification
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Detail enhancement is a well-studied area of 3D rendering and image processing, which has few equivalents for 3D shape processing. To enhance details, one needs an efficient analysis tool to express the local surface ... -
A New Microflake Model With Microscopic Self-shadowing for Accurate Volume Downsampling
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Naive linear methods for downsampling high-resolution microflake volumes often produce inaccurate appearance, especially when input voxels are very opaque. Preserving correct appearance at all resolutions requires taking ... -
Self-similarity Analysis for Motion Capture Cleaning
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Motion capture sequences may contain erroneous data, especially when the motion is complex or performers are interacting closely and occlusions are frequent. Common practice is to have specialists visually detect the ... -
Multiple Scattering in Inhomogeneous Participating Media Using Rao-Blackwellization and Control Variates
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Rendering inhomogeneous participating media requires a lot of volume samples since the extinction coefficient needs to be integrated along light paths. Ray marching makes small steps, which is time consuming and leads to ... -
EUROGRAPHICS 2018: CGF 37-2 Frontmatter
(The Eurographics Association and John Wiley & Sons Ltd., 2018)- -
Improved Functional Mappings via Product Preservation
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we consider the problem of information transfer across shapes and propose an extension to the widely used functional map representation. Our main observation is that in addition to the vector space structure ... -
ExpandNet: A Deep Convolutional Neural Network for High Dynamic Range Expansion from Low Dynamic Range Content
(The Eurographics Association and John Wiley & Sons Ltd., 2018)High dynamic range (HDR) imaging provides the capability of handling real world lighting as opposed to the traditional low dynamic range (LDR) which struggles to accurately represent images with higher dynamic range. ... -
Extended Narrow Band FLIP for Liquid Simulations
(The Eurographics Association and John Wiley & Sons Ltd., 2018)The Fluid Implicit Particle method (FLIP) reduces numerical dissipation by combining particles with grids. To improve performance, the subsequent narrow band FLIP method (NB-FLIP) uses a FLIP-based fluid simulation only ... -
A Versatile Parameterization for Measured Material Manifolds
(The Eurographics Association and John Wiley & Sons Ltd., 2018)A popular approach for computing photorealistic images of virtual objects requires applying reflectance profiles measured from real surfaces, introducing several challenges: the memory needed to faithfully capture realistic ... -
Watch to Edit: Video Retargeting using Gaze
(The Eurographics Association and John Wiley & Sons Ltd., 2018)We present a novel approach to optimally retarget videos for varied displays with di ering aspect ratios by preserving salient scene content discovered via eye tracking. Our algorithm performs editing with cut, pan and ... -
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 ... -
PCPNet: Learning Local Shape Properties from Raw Point Clouds
(The Eurographics Association and John Wiley & Sons Ltd., 2018)In this paper, we propose PCPNET, a deep-learning based approach for estimating local 3D shape properties in point clouds. In contrast to the majority of prior techniques that concentrate on global or mid-level attributes, ... -
Feature Curve Co-Completion in Noisy Data
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Feature curves on 3D shapes provide important hints about significant parts of the geometry and reveal their underlying structure. However, when we process real world data, automatically detected feature curves are affected ... -
Terrain Super-resolution through Aerial Imagery and Fully Convolutional Networks
(The Eurographics Association and John Wiley & Sons Ltd., 2018)Despite recent advances in surveying techniques, publicly available Digital Elevation Models (DEMs) of terrains are lowresolution except for selected places on Earth. In this paper we present a new method to turn low-resolution ... -
Fast Fluid Simulations with Sparse Volumes on the GPU
