A Compact Tucker-Based Factorization Model for Heterogeneous Subsurface Scattering
(The Eurographics Association, 2013)
This paper presents a novel compact factored subsurface scattering representation for optically thick, heterogeneous translucent materials. Our subsurface scattering representation is a combination of Tucker-based factorization ...
Acquisition, Representation and Rendering of Real-World Models using Polynomial Texture Maps in 3D
(The Eurographics Association, 2013)
The ability to represent real-world objects digitally in a realistic manner is an indispensable tool for many applications. This paper proposes a method for acquiring, processing, representing, and rendering these digital ...
GPU Simulation of Finite Element Facial Soft-Tissue Models
(The Eurographics Association, 2013)
Physically-based animation techniques enable more realistic and accurate animation to be created. We present a GPU-based finite element (FE) simulation and interactive visualisation system for efficiently producing ...
Resolution Estimation for Shadow Mapping
(The Eurographics Association, 2013)
We present an approach to efficiently reduce shadow map resolution while retaining high quality hard shadows. In the first step, we generate a list of sample points that are seen from the camera and then project these into ...
Eye-Centered Color Adaptation in Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Color adaptation is a well known ability of the human visual system (HVS). Colors are perceived as constant even though the illuminant color changes. Indeed, the perceived color of a diffuse white sheet of paper is still ...
Enhanced Sphere Tracing
(The Eurographics Association, 2014)
In this paper we present several performance and quality enhancements to classical sphere tracing: First, we propose a safe, over-relaxation-based method for accelerating sphere tracing. Second, a method for dynamically ...
CAVAST: The Crows Animation, Visualization, and Simulation Testbed
(The Eurographics Association, 2014)
Simulation, animation and rendering of crowds has become an important part of real-time applications such as videogames. Virtual environments achieve higher realism when being populated by virtual crowds as opposed to ...
Generating Coherent Ray Directions in Path Tracing
(The Eurographics Association, 2012)
The quality of the images produced by a global illumination rendering engine is highly connected to the number of paths that are randomly generated from the camera to the light sources. Graphics Processing Units (GPUs) ...
Path Tracing on Massively Parallel Neuromorphic Hardware
(The Eurographics Association, 2012)
Ray tracing on parallel hardware has recently benefit from significant advances in the graphics hardware and associated software tools. Despite this, the SIMD nature of graphics card architectures is only able to perform ...
Light Clustering for Dynamic Image Based Lighting
(The Eurographics Association, 2012)
High Dynamic Range (HDR) imagery has made it possible to relight virtual objects accurately with the captured lighting. This technique, called Image Based Lighting (IBL), is a commonly used to render scenes using real-world ...
