Selective Inspection and Interactive Visualization of Light Transport in Virtual Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper presents novel interactive visualization techniques for inspecting the global light transport in virtual scenes. First, we propose a simple extension to photon mapping to gather required lighting information. ... -
SHADOWPIX: Multiple Images from Self Shadowing
(The Eurographics Association and John Wiley and Sons Ltd., 2012)SHADOWPIX are white surfaces that display several prescribed images formed by the self-shadowing of the surface when lit from certain directions. The effect is surprising and not commonly seen in the real world. We present ... -
Iterative Image Warping
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Animated image sequences often exhibit a large amount of inter-frame coherence which standard rendering algorithms and pipelines are ill-equipped to exploit, limiting their efficiency. To address this inefficiency we ... -
Metering for Exposure Stacks
(The Eurographics Association and John Wiley and Sons Ltd., 2012)When creating a High-Dynamic-Range (HDR) image from a sequence of differently exposed Low-Dynamic-Range (LDR) images, the set of LDR images is usually generated by sampling the space of exposure times with a geometric ... -
A Cell-Based Light Interaction Model for Human Blood
(The Eurographics Association and John Wiley and Sons Ltd., 2012)The development of predictive appearance models for organic tissues is a challenging task due to the inherent complexity of these materials. In this paper, we closely examine the biophysical processes responsible for the ... -
Coding Depth through Mask Structure
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a coded-aperture method based on a family of masks obtained as the convolution of one "hole" with a structural component consisting of an arrangement of Dirac delta functions. We call the arrangement of delta ... -
Explicit Mesh Surfaces for Particle Based Fluids
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce the idea of using an explicit triangle mesh to track the air/fluid interface in a smoothed particle hydrodynamics (SPH) simulator. Once an initial surface mesh is created, this mesh is carried forward in time ... -
Importance Caching for Complex Illumination
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Realistic rendering requires computing the global illumination in the scene, and Monte Carlo integration is the best-known method for doing that. The key to good performance is to carefully select the costly integration ... -
Repetition Maximization based Texture Rectification
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Many photographs are taken in perspective. Techniques for rectifying resulting perspective distortions typically rely on the existence of parallel lines in the scene. In scenarios where such parallel lines are hard to ... -
SMAA: Enhanced Subpixel Morphological Antialiasing
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a new image-based, post-processing antialiasing technique, which offers practical solutions to the common, open problems of existing filter-based real-time antialiasing algorithms. Some of the new features include ... -
Medial Kernels
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce the medial kernel, an association measure which provides for a robust construction of volume-aware distances defined directly on point clouds. The medial kernel is a similarity measure defined as the likelihood ... -
Soft Stacking
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In this paper, we present a continuous approach to ordering 2D images when compositing. Previous methods for stacking image layers require them to appear in a single (though possibly different) order at every point in the ... -
Crowd Light: Evaluating the Perceived Fidelity of Illuminated Dynamic Scenes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Rendering realistic illumination effects for complex animated scenes with many dynamic objects or characters is computationally expensive. Yet, it is not obvious how important such accurate lighting is for the overall ... -
Procedural Texture Preview
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Procedural textures usually require spending time testing parameters to realize the diversity of appearances. This paper introduces the idea of a procedural texture preview: A single static image summarizing in a limited ... -
Fast Grasp Synthesis for Various Shaped Objects
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Human-like grasp planning is difficult because a human hand has a high number of degrees of freedom, and there are many grasping styles depending on the shape of an object and purpose. We propose a fast grasp synthesis ... -
Linear Analysis of Nonlinear Constraints for Interactive Geometric Modeling
(The Eurographics Association and John Wiley and Sons Ltd., 2012)Thanks to its flexibility and power to handle even complex geometric relations, 3D geometric modeling with nonlinear constraints is an attractive extension of traditional shape editing approaches. However, existing approaches ... -
crdbrd: Shape Fabrication by Sliding Planar Slices
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We introduce an algorithm and representation for fabricating 3D shape abstractions using mutually intersecting planar cut-outs. The planes have prefabricated slits at their intersections and are assembled by sliding them ... -
Interaction Retrieval by Spacetime Proximity Graphs
(The Eurographics Association and John Wiley and Sons Ltd., 2012)In this paper, we propose a new method to index and retrieve animation scenes in which multiple characters closely interact with one another. Such a technique can be an important tool for animators when they want to ... -
Analytic Anti-Aliasing of Linear Functions on Polytopes
(The Eurographics Association and John Wiley and Sons Ltd., 2012)This paper presents an analytic formulation for anti-aliased sampling of 2D polygons and 3D polyhedra. Our framework allows the exact evaluation of the convolution integral with a linear function defined on the polytopes. ... -
Unstructured Light Fields
(The Eurographics Association and John Wiley and Sons Ltd., 2012)We present a system for interactively acquiring and rendering light fields using a hand-held commodity camera. The main challenge we address is assisting a user in achieving good coverage of the 4D domain despite the ...
