AA Patterns
(The Eurographics Association, 2011)AA Patterns is the name of a recently developed algorithmic art technique that employs a simple linear 2D transform to generate ornamental patterns of pixels. The patterns are controlled by a single real parameter between ... -
Accelerated 5D Ray Tree construction on the GPU
(The Eurographics Association, 2011)Ray tracing random rays has been a challenge. Due to their reduced coherence, the normal methods of acceleration like packet tracing that make use of coherence of the rays do not work well. These random rays are encountered ... -
Acoustic Rendering and Auditory-Visual Cross-Modal Perception and Interaction
(The Eurographics Association, 2011)In recent years research in the 3-Dimensional sound generation field has been primarily focussed upon new applications of spatialised sound. In the computer graphics community the use of such techniques is most commonly ... -
Alpha Compression with Variable Data Formats
(The Eurographics Association, 2011)Based on the insight into the essential differences between transparency and color, we present a novel alpha compression scheme, called EAC (Enhanced Alpha Compression), as an improvement to that of DXT5. EAC defines new ... -
Application of Active Appearance Model to Automatic Face Replacement
(The Eurographics Association, 2011)Active appearance models (AAM) are statistical model for capturing shape as well as appearance of deformable objects like human face. The power of AAM lies in the fact that it can synthesis or explain any given object shape ... -
Architectural Styles Dependent Shape Grammar Representation of Facades
(The Eurographics Association, 2011)In this poster, we present an idea to utilize formal rules and descriptions for architectural styles from various time periods. We focus on facades of historical buildings with identical purpose located in a specific ... -
The Art and Science of Digital Production Arts
(The Eurographics Association, 2011)As its name implies, digital production arts incorporates both technical and artistic aspects. The challenge of any program in this discipline is to balance these two components in such a way that each enhances the other ... -
Artistic Stylisation of Images and Video
(The Eurographics Association, 2011)The half-day tutorial provides an introduction to Non- Photorealistic Rendering (NPR), targeted at both students and experienced researchers of Computer Graphics who have not previously explored NPR in their work. The ... -
Automatic Stream Surface Seeding
(The Eurographics Association, 2011)The visualisation of 3D flow poses many challenges. Difficulties can stem from attempting to capture all flow features, the speed of computation, and spatial perception. Streamlines and stream surfaces are standard tools ... -
AVM-Explorer: Multi-Volume Visualization of Vascular Structures for Planning of Cerebral AVM Surgery
(The Eurographics Association, 2011)Arteriovenous malformations (AVMs) of the brain are rare vascular disorders characterized by the presence of direct connections between cerebral arteries and veins. Preoperative planning of AVM surgery is a challenging ... -
Avoiding Chromaticity Creep with PseudoGrey
(The Eurographics Association, 2011)We examine the calibration of Commodity, Off-The-Shelf (COTS) monitors to the DICOM GreyScale Display Function (GSDF) standard (as used for medical imaging). We note that uncalibrated and calibrated (using commercial and ... -
Believable Virtual Characters in Human-Computer Dialogs
(The Eurographics Association, 2011)For many application areas, where a task is most naturally represented by talking or where standard input devices are difficult to use or not available at all, virtual characters can be well suited as an intuitive ... -
Blur-Aware Image Downsampling
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Resizing to a lower resolution can alter the appearance of an image. In particular, downsampling an image causes blurred regions to appear sharper. It is useful at times to create a downsampled version of the image that ... -
BSSRDF Estimation from Single Images
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a novel method to estimate an approximation of the reflectance characteristics of optically thick, homogeneous translucent materials using only a single photograph as input. First, we approximate the diffusion ... -
Collision-Driven Volumetric Deformation on the GPU
(The Eurographics Association, 2011)We present a novel parallel algorithm to animate the deformation of a soft body in response to collision. Our algorithm incorporates elements of physically-based methods, and at the same time, it allows artistic control ... -
Combinatorial Bidirectional Path-Tracing for Efficient Hybrid CPU/GPU Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)This paper presents a reformulation of bidirectional path-tracing that adequately divides the algorithm into processes efficiently executed in parallel on both the CPU and the GPU. We thus benefit from high-level optimization ... -
Component-wise Controllers for Structure-Preserving Shape Manipulation
(The Eurographics Association and Blackwell Publishing Ltd., 2011)Recent shape editing techniques, especially for man-made models, have gradually shifted focus from maintaining local, low-level geometric features to preserving structural, high-level characteristics like symmetry and ... -
Comprehensive Facial Performance Capture
(The Eurographics Association and Blackwell Publishing Ltd., 2011)We present a system for recording a live dynamic facial performance, capturing highly detailed geometry and spatially varying diffuse and specular reflectance information for each frame of the performance. The result is a ... -
Computational Plenoptic Imaging
(The Eurographics Association, 2011)The plenoptic function is a ray-based model for light that includes the color spectrum as well as spatial, temporal, and directional variation. Although digital light sensors have greatly evolved in the last years, one ...
