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 ...
A Unified Manifold Framework for Efficient BRDF Sampling based on Parametric Mixture Models
(The Eurographics Association, 2018)
Virtually all existing analytic BRDF models are built from multiple functional components (e.g., Fresnel term, normal distribution function, etc.). This makes accurate importance sampling of the full model challenging, and ...
Direct Raytracing of Particle-based Fluid Surfaces Using Anisotropic Kernels
(The Eurographics Association, 2018)
Particle-based simulation models have assumed a significant role in the numerical computation of high-fidelity transient flow and continuum mechanical problems. However, direct visualization of surfaces from particle data ...
Towards a Principled Kernel Prediction for Spatially Varying BSSRDFs
(The Eurographics Association, 2018)
While the modeling of sub-surface translucency using homogeneous BSSRDFs is an established industry standard, applying the same approach to heterogeneous materials is predominantly heuristical. We propose a more principled ...
On the Advancement of BTF Measurement on Site
(The Eurographics Association, 2018)
We present our progress to the on-site measurement of the spatially varying surface reflectance represented by bidirectional texture function (BTF). This requires a physical realization of a portable instrument that can ...
Towards Physically Based Material Appearance in the Thermal Infrared Spectrum: A Short Survey
(The Eurographics Association, 2018)
In the context of photorealistic rendering, global illumination mainly relies on material models from the visible spectrum, whereas thermal infrared signatures receive only little attention. This paper outlines physical ...
Iso Photographic Rendering
(The Eurographics Association, 2018)
In the field of computer graphics, the simulation of the visual appearance of materials requires an accurate computation of the light transport equation. Consequently, material models need to take into account various ...
