Bitmask Soft Shadows
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
Recently, several real-time soft shadow algorithms have been introduced which all compute a single shadow map and use its texels to obtain a discrete scene representation. The resulting micropatches are backprojected onto ...
Textured Liquids based on the Marker Level Set
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this work we propose a new Eulerian method for handling the dynamics of a liquid and its surface attributes (for example its color). Our approach is based on a new method for interface advection that we term the Marker ...
Precomputed Radiance Transfer Field for Rendering Interreflections in Dynamic Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper, we introduce a new representation - radiance transfer fields (RTF) - for rendering interreflections in dynamic scenes under low frequency illumination. The RTF describes the radiance transferred by an ...
Efficient Reflectance and Visibility Approximations for Environment Map Rendering
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We present a technique for approximating isotropic BRDFs and precomputed self-occlusion that enables accurate and efficient prefiltered environment map rendering. Our approach uses a nonlinear approximation of the BRDF as ...
Online Motion Capture Marker Labeling for Multiple Interacting Articulated Targets
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper, we propose an online motion capture marker labeling approach for multiple interacting articulated targets. Given hundreds of unlabeled motion capture markers from multiple articulated targets that are ...
Interactive Visual Workspaces with Dynamic Foveal Areas and Adaptive Composite Interfaces
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
This paper presents novel techniques and metaphors for on-demand visual workspaces in everyday office environments, providing space-efficient, flexible and highly interactive graphical user interfaces using projected ...
Shape-aware Volume Illustration
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
We introduce a novel volume illustration technique for regularly sampled volume datasets. The fundamental difference between previous volume illustration algorithms and ours is that our results are shape-aware, as they ...
Consistent Viewing and Interaction for Multiple Users in Projection-Based VR Systems
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In projection-based Virtual Reality (VR) systems, typically only one headtracked user views stereo images rendered from the correct view position. For other users, who are presented a distorted image, moving with the first ...
A Bidirectional Light Field - Hologram Transform
(The Eurographics Association and Blackwell Publishing Ltd, 2007)
In this paper, we propose a novel framework to represent visual information. Extending the notion of conventional image-based rendering, our framework makes joint use of both light fields and holograms as complementary ...
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 ...
