Manifold-Based 3D Face Caricature Generation with Individualized Facial Feature Extraction
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Caricature is an interesting art to express exaggerated views of different persons and things through drawing. The face caricature is popular and widely used for different applications. To do this, we have to properly ... -
Metalights: Improved Interleaved Shading
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present metalights, a novel Virtual Point Light (VPL) encapsulating structure which enhances classic interleaved shading by improving VPL sampling, based on few initial screen space samples to estimate VPL contribution ... -
Modeling Complex Unfoliaged Trees from a Sparse Set of Images
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a novel image-based technique for modeling complex unfoliaged trees. Existing tree modeling tools either require capturing a large number of views for dense 3D reconstruction or rely on user inputs and botanic ... -
Modeling of Clouds from a Single Photograph
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we propose a simple method for modeling clouds from a single photograph. Our method can synthesize three types of clouds: cirrus, altocumulus, and cumulus. We use three different representations for each ... -
Multi-Resolution Cloth Simulation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We propose a novel, multi-resolution method to efficiently perform large-scale cloth simulation. Our cloth simulation method is based on a triangle-based energy model constructed from a cloth mesh. We identify that solutions ... -
Polygonal Surface Advection applied to Strange Attractors
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Strange attractors of 3D vector field flows sometimes have a fractal geometric structure in one dimension, and smooth surface behavior in the other two. General flow visualization methods show the flow dynamics well, but ... -
Real-time Depth of Field Rendering via Dynamic Light Field Generation and Filtering
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a new algorithm for efficient rendering of high-quality depth-of-field (DoF) effects. We start with a single rasterized view (reference view) of the scene, and sample the light field by warping the reference ... -
Semi-isometric Registration of Line Features for Flexible Fitting of Protein Structures
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we study a registration problem that is motivated by a practical biology problem - fitting protein structures to low-re solution density maps. We consider registration between two sets of lines features ... -
A simple and robust thinning algorithm on cell complexes
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Thinning is a commonly used approach for computing skeleton descriptors. Traditional thinning algorithms often have a simple, iterative structure, yet producing skeletons that are overly sensitive to boundary perturbations. ... -
Towards Perceptual Simplification of Models with Arbitrary Materials
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Real-time rendering of models with high polygon count is still an important issue in interactive computer graphics. A common way to improve rendering performance is to generate different levels of detail of a model. These ... -
Variance Soft Shadow Mapping
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present variance soft shadow mapping (VSSM) for rendering plausible soft shadow in real-time. VSSM is based on the theoretical framework of percentage-closer soft shadows (PCSS) and exploits recent advances in variance ... -
Video Painting via Motion Layer Manipulation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Temporal coherence is an important problem in Non-Photorealistic Rendering for videos. In this paper, we present a novel approach to enhance temporal coherence in video painting. Instead of painting on video frame, our ...
