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 ...
Improving the Dwivedi Sampling Scheme
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Despite recent advances in Monte Carlo rendering techniques, dense, high-albedo participating media such as wax or skin still remain a difficult problem. In such media, random walks tend to become very long, but may still ...
Path Space Regularization for Holistic and Robust Light Transport
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We propose a simple yet powerful regularization framework for robust light transport simulation. It builds on top of existing unbiased methods and resorts to a consistent estimation using regularization only for paths which ...
Rich-VPLs for Improving the Versatility of Many-Light Methods
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Many-light methods approximate the light transport in a scene by computing the direct illumination from many virtual point light sources (VPLs), and render low-noise images covering a wide range of performance and quality ...
Stochastic Soft Shadow Mapping
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In this paper, we extend the concept of pre-filtered shadow mapping to stochastic rasterization, enabling real-time rendering of soft shadows from planar area lights. Most existing soft shadow mapping methods lose important ...
Physically Meaningful Rendering using Tristimulus Colours
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In photorealistic image synthesis the radiative transfer equation is often not solved by simulating every wavelength of light, but instead by computing tristimulus transport, for instance using sRGB primaries as a basis. ...
Improved Half Vector Space Light Transport
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
In this paper, we present improvements to half vector space light transport (HSLT) [KHD14], which make this approach more practical, robust for difficult input geometry, and faster. Our first contribution is the computation ...
Progressive Virtual Beam Lights
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
A recent technique that forms virtual ray lights (VRLs) from path segments in media, reduces the artifacts common to VPL approaches in participating media, however, distracting singularities still remain. We present Virtual ...
