Visibility Sampling on GPU and Applications
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper, we show how recent GPUs can be used to very efficiently and conveniently sample the visibility between two surfaces, given a set of occluding triangles. We use bitwise arithmetics to evaluate, encode, and ...
Merged Multiresolution Hierarchies for Shadow Map Compression
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
Multiresolution Hierarchies (MH) and Directed Acyclic Graphs (DAG) are two recent approaches for the compression of highresolution shadow information. In this paper, we introduce Merged Multiresolution Hierarchies (MMH), ...
Efficient Ray Tracing Through Aspheric Lenses and Imperfect Bokeh Synthesis
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
We present an efficient ray-tracing technique to render bokeh effects produced by parametric aspheric lenses. Contrary to conventional spherical lenses, aspheric lenses do generally not permit a simple closed-form solution ...
Gradient‐Guided Local Disparity Editing
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
Stereoscopic 3D technology gives visual content creators a new dimension of design when creating images and movies. While useful for conveying emotion, laying emphasis on certain parts of the scene, or guiding the viewer's ...
ShutterApp: Spatio-temporal Exposure Control for Videos
(The Eurographics Association and John Wiley & Sons Ltd., 2019)
A camera's shutter controls the incoming light that is reaching the camera sensor. Different shutters lead to wildly different results, and are often used as a tool in movies for artistic purpose, e.g., they can indirectly ...
MegaViews: Scalable Many‐View Rendering With Concurrent Scene‐View Hierarchy Traversal
(© 2019 The Eurographics Association and John Wiley & Sons Ltd., 2019)
We present a scalable solution to render complex scenes from a large amount of viewpoints. While previous approaches rely either on a scene or a view hierarchy to process multiple elements together, we make full use of ...
Cytosplore: Interactive Immune Cell Phenotyping for Large Single-Cell Datasets
(The Eurographics Association and John Wiley & Sons Ltd., 2016)
To understand how the immune system works, one needs to have a clear picture of its cellular compositon and the cells' corresponding properties and functionality. Mass cytometry is a novel technique to determine the ...
Practical Real-Time Lens-Flare Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2013)
We present a practical real-time approach for rendering lens-flare effects. While previous work employed costly ray tracing or complex polynomial expressions, we present a coarser, but also significantly faster solution. ...
ManyLoDs: Parallel Many-View Level-of-Detail Selection for Real-Time Global Illumination
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Level-of-Detail structures are a key component for scalable rendering. Built from raw 3D data, these structures are often defined as Bounding Volume Hierarchies, providing coarse-to-fine adaptive approximations that are ...
General and Robust Error Estimation and Reconstruction for Monte Carlo Rendering
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Adaptive filtering techniques have proven successful in handling non-uniform noise in Monte-Carlo rendering approaches. A recent trend is to choose an optimal filter per pixel from a selection of non spatially-varying ...
