Multiple Vertex Next Event Estimation for Lighting in dense, forward-scattering Media
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a new technique called Multiple Vertex Next Event Estimation, which outperforms current direct lighting techniques in forward scattering, optically dense media with the Henyey-Greenstein phase function. Instead ...
Sparse High-degree Polynomials for Wide-angle Lenses
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Rendering with accurate camera models greatly increases realism and improves the match of synthetic imagery to real-life footage. Photographic lenses can be simulated by ray tracing, but the performance depends on the ...
Local Quasi-Monte Carlo Exploration
(The Eurographics Association, 2017)
In physically-based image synthesis, the path space of light transport paths is usually explored by stochastic sampling. The two main families of algorithms are Monte Carlo/quasi-Monte Carlo sampling and Markov chain Monte ...
An Interactive Information Visualization Approach to Physically-Based Rendering
(The Eurographics Association, 2016)
In this work, we present a novel information visualization tool to gain insight into the light transport in a physically-based rendering setting. The tool consists of a sampling-based data reduction technique, an extended ...
Progressive Visibility Caching for Fast Indirect Illumination
(The Eurographics Association, 2013)
Rendering realistic images requires exploring the vast space of all possible paths that light can take between emitters and receivers. Thanks to the advances in rendering we can tackle this problem using different algorithms; ...
Interactive Direct Volume Rendering with Many-light Methods and Transmittance Caching
(The Eurographics Association, 2013)
In this paper we present an interactive global illumination method for Direct Volume Rendering (DVR) based on the many-light approach, a class of global illumination methods which gained much interest recently. We extend ...
A Phenomenological Approach to Integrating Gaussian Beam Properties and Speckle into a Physically-Based Renderer
(The Eurographics Association, 2016)
Coherent light exhibits properties that cannot be modeled by geometrical optics. Those properties include the limited focusability of light beams and the formation of speckle patterns when coherent light is scattered or ...
Memory-Efficient On-The-Fly Voxelization of Particle Data
(The Eurographics Association, 2015)
In this paper we present a novel GPU-friendly real-time voxelization technique for rendering homogeneous media that is defined by particles, e.g. fluids obtained from particle-based simulations such as Smoothed Particle ...
Spectral Rendering with the Bounded MESE and sRGB Data
(The Eurographics Association, 2019)
In a recent journal paper, we introduced a technique to represent reflectance spectra by an arbitrary number of Fourier coefficients. As a special case, we converted tristimulus data to three Fourier coefficients. After ...
Adaptive Quantization Visibility Caching
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
Ray tracing has become a viable alternative to rasterization for interactive applications and also forms the basis of most global illumination methods. However, even today's fastest ray-tracers offer only a tight budget ...
