Real-time Realistic Ocean Lighting using Seamless Transitions from Geometry to BRDF
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Realistic animation and rendering of the ocean is an important aspect for simulators, movies and video games. By nature, the ocean is a difficult problem for Computer Graphics: it is a dynamic system, it combines wave ... -
Real-time Rendering of Heterogeneous Translucent Objects with Arbitrary Shapes
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a real-time algorithm for rendering translucent objects of arbitrary shapes. We approximate the scattering of light inside the objects using the diffusion equation, which we solve on-the-fly using the GPU. Our ... -
Reinterpretable Imager: Towards Variable Post-Capture Space, Angle and Time Resolution in Photography
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We describe a novel multiplexing approach to achieve tradeoffs in space, angle and time resolution in photography. We explore the problem of mapping useful subsets of time-varying 4D lightfields in a single snapshot. Our ... -
Rendering Wave Effects with Augmented Light Field
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Ray-based representations can model complex light transport but are limited in modeling diffraction effects that require the simulation of wavefront propagation. This paper provides a new paradigm that has the simplicity ... -
Scalable Height Field Self-Shadowing
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a new method suitable for general purpose graphics processing units to render self-shadows on dynamic height fields under dynamic light environments in real-time. Visibility for each point in the height field ... -
Seamless Montage for Texturing Models
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present an automatic method to recover high-resolution texture over an object by mapping detailed photographs onto its surface. Such high-resolution detail often reveals inaccuracies in geometry and registration, as ... -
Shared Sampling for Real-Time Alpha Matting
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Image matting aims at extracting foreground elements from an image by means of color and opacity (alpha) estimation. While a lot of progress has been made in recent years on improving the accuracy of matting techniques, ... -
Sketching Clothoid Splines Using Shortest Paths
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Clothoid splines are gaining popularity as a curve representation due to their intrinsically pleasing curvature, which varies piecewise linearly over arc length. However, constructing them from hand-drawn strokes remains ... -
SoundRiver: Semantically-Rich Sound Illustration
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Sound is an integral part of most movies and videos. In many situations, viewers of a video are unable to hear the sound track, for example, when watching it in a fast forward mode, viewing it by hearing-impaired viewers ... -
Synthesis of Responsive Motion Using a Dynamic Model
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Synthesizing the movements of a responsive virtual character in the event of unexpected perturbations has proven a difficult challenge. To solve this problem, we devise a fully automatic method that learns a nonlinear ... -
Tetrahedral Embedded Boundary Methods for Accurate and Flexible Adaptive Fluids
(The Eurographics Association and Blackwell Publishing Ltd, 2010)When simulating fluids, tetrahedral methods provide flexibility and ease of adaptivity that Cartesian grids find difficult to match. However, this approach has so far been limited by two conflicting requirements. First, ... -
TouchTone: Interactive Local Image Adjustment Using Point-and-Swipe
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Recent proliferation of camera phones, photo sharing and social network services has significantly changed how we process our photos. Instead of going through the traditional download-edit-share cycle using desktop editors, ... -
Two-Colored Pixels
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper we show how to use two-colored pixels as a generic tool for image processing. We apply two-colored pixels as a basic operator as well as a supporting data structure for several image processing applications. ... -
Uncertain 2D Vector Field Topology
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We introduce an approach to visualize stationary 2D vector fields with global uncertainty obtained by considering the transport of local uncertainty in the flow. For this, we extend the concept of vector field topology to ... -
User-Controllable Color Transfer
(The Eurographics Association and Blackwell Publishing Ltd, 2010)This paper presents an image editing framework where users use reference images to indicate desired color edits. In our approach, users specify pairs of strokes to indicate corresponding regions in both the original and ... -
The Virtual Director: a Correlation-Based Online Viewing of Human Motion
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Automatic camera control for scenes depicting human motion is an imperative topic in motion capture base animation, computer games, and other animation based fields. This challenging control problem is complex and combines ...
