Interactive Indirect Illumination Using Voxel Cone Tracing
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Indirect illumination is an important element for realistic image synthesis, but its computation is expensive and highly dependent on the complexity of the scene and of the BRDF of the involved surfaces. While off-line ...
Making Imperfect Shadow Maps View‐Adaptive: High‐Quality Global Illumination in Large Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
We propose an algorithm to compute interactive indirect illumination in dynamic scenes containing millions of triangles. It makes use of virtual point lights (VPL) to compute bounced illumination and a point‐based scene ...
Temporal Coherence Methods in Real‐Time Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Nowadays, there is a strong trend towards rendering to higher‐resolution displays and at high frame rates. This development aims at delivering more detail and better accuracy, but it also comes at a significant cost. ...
Computational Light Painting Using a Virtual Exposure
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Light painting is an artform where a light source is moved during a long-exposure shot, creating trails resembling a stroke on a canvas. It is very difficult to perform because the light source needs to be moved at the ...
Overview + Detail Visualization for Ensembles of Diffusion Tensors
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
A Diffusion Tensor Imaging (DTI) group study consists of a collection of volumetric diffusion tensor datasets (i.e., an ensemble) acquired from a group of subjects. The multivariate nature of the diffusion tensor imposes ...
Split-Depth Image Generation and Optimization
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Split-depth images use an optical illusion, which can enhance the 3D impression of a 2D animation. In split-depth images (also often called split-depth GIFs due to the commonly used file format), static virtual occluders ...
Spectral Processing of Tangential Vector Fields
(© 2017 The Eurographics Association and John Wiley & Sons Ltd., 2017)
We propose a framework for the spectral processing of tangential vector fields on surfaces. The basis is a Fourier‐type representation of tangential vector fields that associates frequencies with tangential vector fields. ...
Multiscale Visualization and Exploration of Large Bipartite Graphs
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
A bipartite graph is a powerful abstraction for modeling relationships between two collections. Visualizations of bipartite graphs allow users to understand the mutual relationships between the elements in the two collections, ...
Spectral Gradient Sampling for Path Tracing
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Spectral Monte-Carlo methods are currently the most powerful techniques for simulating light transport with wavelengthdependent phenomena (e.g., dispersion, colored particle scattering, or diffraction gratings). Compared ...
Quad-Based Fourier Transform for Efficient Diffraction Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2018)
Far-field diffraction can be evaluated using the Discrete Fourier Transform (DFT) in image space but it is costly due to its dense sampling. We propose a technique based on a closed-form solution of the continuous Fourier ...
