Ray Casting Algebraic Surfaces using the Frustum Form
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We propose an algorithm for interactive ray-casting of algebraic surfaces of high degree. A key point of our approach is a polynomial form adapted to the view frustum. This so called frustum form yields simple expressions ... -
Real-Time Rendering and Editing of Vector-based Terrains
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a method to populate very large terrains with very detailed features such as roads, rivers, lakes and fields. These features can be interactively edited, and the landscape can be explored in real time at any ... -
Real-Time Translucent Rendering Using GPU-based Texture Space Importance Sampling
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a novel approach for real-time rendering of translucent surfaces. The computation of subsurface scattering is performed by first converting the integration over the 3D model surface into an integration over a ... -
Reduced Depth and Visual Hulls of Complex 3D Scenes
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Depth and visual hulls are useful for quick reconstruction and rendering of a 3D object based on a number of reference views. However, for many scenes, especially multi-object, these hulls may contain significant artifacts ... -
Render2MPEG: A Perception-based Framework Towards Integrating Rendering and Video Compression
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Currently 3D animation rendering and video compression are completely independent processes even if rendered frames are streamed on-the-fly within a client-server platform. In such scenario, which may involve time-varying ... -
A Semi-Lagrangian CIP Fluid Solver without Dimensional Splitting
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper, we propose a new constrained interpolation profile (CIP) method that is stable and accurate but requires less amount of computation compared to existing CIP-based solvers. CIP is a high-order fluid advection ... -
The Shadow Meets the Mask: Pyramid-Based Shadow Removal
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we propose a novel method for detecting and removing shadows from a single image thereby obtaining a high-quality shadow-free image. With minimal user assistance, we first identify shadowed and lit areas on ... -
Simulation of Human Motion Data using Short-Horizon Model-Predictive Control
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Many data-driven animation techniques are capable of producing high quality motions of human characters. Few techniques, however, are capable of generating motions that are consistent with physically simulated environments. ... -
Single-pass Scalable Subsurface Rendering with Lightcuts
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper presents a new, scalable, single pass algorithm for computing subsurface scattering using the diffusion approximation. Instead of pre-computing a globally conservative estimate of the surface irradiance like ... -
Sketch-Based Procedural Surface Modeling and Compositing Using Surface Trees
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present a system for creating and manipulating layered procedural surface editing operations, which is motivated by the limited support for iterative design in free-form modeling. A combination of sketch-based and ... -
Sketching and Composing Widgets for 3D Manipulation
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present an interface for 3D object manipulation in which standard transformation tools are replaced with transient 3D widgets invoked by sketching context-dependent strokes. The widgets are automatically aligned to axes ... -
Sparse points matching by combining 3D mesh saliency with statistical descriptors
(The Eurographics Association and Blackwell Publishing Ltd, 2008)This paper proposes new methodology for the detection and matching of salient points over several views of an object. The process is composed by three main phases. In the first step, detection is carried out by adopting a ... -
Spectral Geometry Processing with Manifold Harmonics
(The Eurographics Association and Blackwell Publishing Ltd, 2008)We present an explicit method to compute a generalization of the Fourier Transform on a mesh. It is well known that the eigenfunctions of the Laplace Beltrami operator (Manifold Harmonics) define a function basis allowing ... -
Stereo Light Probe
(The Eurographics Association and Blackwell Publishing Ltd, 2008)In this paper we present a practical, simple and robust method to acquire the spatially-varying illumination of a real-world scene. The basic idea of the proposed method is to acquire the radiance distribution of the scene ... -
Surface Reconstruction From Non-parallel Curve Networks
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Building surfaces from cross-section curves has wide applications including bio-medical modeling. Previous work in this area has mostly focused on connecting simple closed curves on parallel cross-sections. Here we consider ... -
Texture Synthesis From Photographs
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The goal of texture synthesis is to generate an arbitrarily large high-quality texture from a small input sample. Generally, it is assumed that the input image is given as a flat, square piece of texture, thus it has to ... -
Video Relighting Using Infrared Illumination
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Inappropriate lighting is often responsible for poor quality video. In most offices and homes, lighting is not designed for video conferencing. This can result in unevenly lit faces, distracting shadows, and unnatural ... -
Viewfinder Alignment
(The Eurographics Association and Blackwell Publishing Ltd, 2008)The viewfinder of a digital camera has traditionally been used for one purpose: to display to the user a preview of what is seen through the camera s lens. High quality cameras are now available on devices such as mobile ... -
Visualizing Underwater Ocean Optics
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Simulating the in-water ocean light field is a daunting task. Ocean waters are one of the richest participating media, where light interacts not only with water molecules, but with suspended particles and organic matter ... -
Zippy: A Framework for Computation and Visualization on a GPU Cluster
(The Eurographics Association and Blackwell Publishing Ltd, 2008)Due to its high performance/cost ratio, a GPU cluster is an attractive platform for large scale general-purpose computation and visualization applications. However, the programming model for high performance general-purpose ...
