GPU-Based Nonlinear Ray Tracing
(The Eurographics Association and Blackwell Publishing, Inc, 2004)In this paper, we present a mapping of nonlinear ray tracing to the GPU which avoids any data transfer back to main memory. The rendering process consists of the following parts: ray setup according to the camera parameters, ... -
Hardware-Accelerated Rendering of Photo Hulls
(The Eurographics Association and Blackwell Publishing, Inc, 2004)This paper presents an efficient hardware-accelerated method for novel view synthesis from a set of images or videos. Our method is based on the photo hull representation, which is the maximal photo-consistent shape. We ... -
Hierarchical Retargetting of Fine Facial Motions
(The Eurographics Association and Blackwell Publishing, Inc, 2004)We present a novel technique for retargetting captured facial animation to new facial models. We use dense motion data that can express fine motions such as wrinkles. We use a normal mesh, which is a special multi-resolution ... -
High Quality Hatching
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Hatching lines are often used in line illustrations to convey tone and texture of a surface. In this paper we present methods to generate hatching lines from polygonal meshes and render them in high quality either at ... -
High Resolution Acquisition, Learning and Transfer of Dynamic 3-D Facial Expressions
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Synthesis and re-targeting of facial expressions is central to facial animation and often involves significant manual work in order to achieve realistic expressions, due to the difficulty of capturing high quality dynamic ... -
Image-based Relighting, and Computer Vision
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Image-based techniques have become very popular over the past couple of years. Ranging from modeling to rendering and lighting, the use of images as direct input for graphics algorithms has become as important as processing ... -
Immersive Integration of Physical and Virtual Environments
(The Eurographics Association and Blackwell Publishing, Inc, 2004)We envision future work and play environments in which the user's computing interface is more closely integrated with the physical surroundings than today's conventional computer display screens and keyboards.We are working ... -
Implicit Visualization and Inverse Modeling of Growing Trees
(The Eurographics Association and Blackwell Publishing, Inc, 2004)A method is proposed for photo-realistic modeling and visualization of a growing tree. Recent visualization methods have focused on producing smoothly blending branching structures, however, these methods fail to account ... -
Instant Volumetric Understanding with Order-Independent Volume Rendering
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Rapid, visual understanding of volumetric datasets is a crucial outcome of a good volume rendering application, but few current volume rendering systems deliver this result. Our goal is to reduce the volumetric surfing ... -
Interference Detection for Subdivision Surfaces
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Accurate and robust interference detection and ray-tracing of subdivision surfaces requires safe linear approximations. Approximation of the limit surface by the subdivided control polyhedron can be both inaccurate and, ... -
Measurement-Based Interactive Simulation of Viscoelastic Solids
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Animation of viscoelastic solids in entertainment and medical applications as well as scientific simulation can be improved through observations of real world objects. This paper presents a method for simulating viscoelastic ... -
Optimized Sub-Sampling of Point Sets for Surface Splatting
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Using surface splats as a rendering primitive has gained increasing attention recently due to its potential for high-performance and high-quality rendering of complex geometric models. However, as with any other rendering ... -
A Physically-Based Model for Rendering Realistic Scratches
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Individually visible scratches, also called isolated scratches, are very common in real world surfaces. Although their microgeometry is not visible, they are individually perceptible by the human eye, lying into a ... -
Point Cloud Collision Detection
(The Eurographics Association and Blackwell Publishing, Inc, 2004)In the past few years, many efficient rendering and surface reconstruction algorithms for point clouds have been developed. However, collision detection of point clouds has not been considered until now, although this is ... -
Procedural Texture Matching and Transformation
(The Eurographics Association and Blackwell Publishing, Inc, 2004)We present a technique for creating a smoothly varying sequence of procedural textures that interpolates between arbitrary input samples of texture. This texture transformation uses a library of procedural shaders and ... -
A Progressive Rendering Algorithm Using an Adaptive Perceptually Based Image Metric
(The Eurographics Association and Blackwell Publishing, Inc, 2004)In this paper, we propose to solve the global illumination problem through a progressive rendering method relying on an adaptive sampling of the image space. The refinement of this sample scheme is driven by an image metric ... -
Quadric Transfer for Immersive Curved Screen Displays
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Curved screens are increasingly being used for high-resolution immersive visualization environments. We describe a new technique to display seamless images using overlapping projectors on curved quadric surfaces such as ... -
Real-time Light Animation
(The Eurographics Association and Blackwell Publishing, Inc, 2004)Light source animation is a particularly hard field of real-time global illumination algorithms since moving light sources result in drastic illumination changes and make coherence techniques less effective. However, the ... -
Real-time Rigid Body Simulation for Haptic Interactions Based on Contact Volume of Polygonal Objects
(The Eurographics Association and Blackwell Publishing, Inc, 2004)This paper proposes a new method for real-time rigid body simulations for haptic interactions based on a penalty method regarding contact volume. Analytical methods for calculation of contact forces require too much time ... -
Rendering with Spherical Radiance Transport Maps
(The Eurographics Association and Blackwell Publishing, Inc, 2004)In this paper, we propose a real-time method for rendering soft shadows and inter-reflections of dynamic objects under complex illumination. In previous methods, many efforts were taken to acquire occlusion and reflection ...
