Implicit Blending Revisited
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Blending is both the strength and the weakness of functionally based implicit surfaces (such as F-reps or soft-objects). While it gives them the unique ability to smoothly merge into a single, arbitrary shape, it makes ... -
Improved Variational Guiding of Smoke Animations
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Smoke animations are hard to art-direct because simple changes in parameters such as simulation resolution often lead to unpredictable changes in the final result. Previous work has addressed this problem with a guiding ... -
Interactive High-Quality Visualization of Higher-Order Finite Elements
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Higher-order finite element methods have emerged as an important discretization scheme for simulation. They are increasingly used in contemporary numerical solvers, generating a new class of data that must be analyzed by ... -
Inverse Procedural Modeling by Automatic Generation of L-systems
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present an important step towards the solution of the problem of inverse procedural modeling by generating parametric context-free L-systems that represent an input 2D model. The L-system rules efficiently code the ... -
Isosurfaces Over Simplicial Partitions of Multiresolution Grids
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We provide a simple method that extracts an isosurface that is manifold and intersection-free from a function over an arbitrary octree. Our method samples the function dual to minimal edges, faces, and cells, and we show ... -
Mesh Decomposition with Cross-Boundary Brushes
(The Eurographics Association and Blackwell Publishing Ltd, 2010)We present a new intuitive UI, which we call cross-boundary brushes, for interactive mesh decomposition. The user roughly draws one or more strokes across a desired cut and our system automatically returns a best cut running ... -
Mesh Snapping: Robust Interactive Mesh Cutting Using Fast Geodesic Curvature Flow
(The Eurographics Association and Blackwell Publishing Ltd, 2010)This paper considers the problem of interactively finding the cutting contour to extract components from a given mesh. Some existing methods support cuts of arbitrary shape but require careful and tedious input from the ... -
Motion Blur for EWA Surface Splatting
(The Eurographics Association and Blackwell Publishing Ltd, 2010)This paper presents a novel framework for elliptical weighted average (EWA) surface splatting with time-varying scenes. We extend the theoretical basis of the original framework by replacing the 2D surface reconstruction ... -
Multi-Scale Geometry Interpolation
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Interpolating vertex positions among triangle meshes with identical vertex-edge graphs is a fundamental part of many geometric modelling systems. Linear vertex interpolation is robust but fails to preserve local shape. ... -
Optimizing Photo Composition
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Aesthetic images evoke an emotional response that transcends mere visual appreciation. In this work we develop a novel computational means for evaluating the composition aesthetics of a given image based on measuring several ... -
Perceptually-motivated Real-time Temporal Upsampling of 3D Content for High-refresh-rate Displays
(The Eurographics Association and Blackwell Publishing Ltd, 2010)High-refresh-rate displays (e. g., 120 Hz) have recently become available on the consumer market and quickly gain on popularity. One of their aims is to reduce the perceived blur created by moving objects that are tracked ... -
Practical quad mesh simplification
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper we present an innovative approach to incremental quad mesh simplification, i.e. the task of producing a low complexity quad mesh starting from a high complexity one. The process is based on a novel set of ... -
Printed Patterns for Enhanced Shape Perception of Papercraft Models
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Papercraft models can serve as inexpensive prototypes in shape design applications. However, in making the models some geometric detail is necessarily lost, and artificial creases may be visible, thereby limiting the utility ... -
Procedural Generation of Roads
(The Eurographics Association and Blackwell Publishing Ltd, 2010)In this paper, we propose an automatic method for generating roads based on a weighted anisotropic shortest path algorithm. Given an input scene, we automatically create a path connecting an initial and a final point. The ... -
Puzzle-like Collage
(The Eurographics Association and Blackwell Publishing Ltd, 2010)Collages have been a common form of artistic expression since their first appearance in China around 200 BC. Recently, with the advance of digital cameras and digital image editing tools, collages have gained popularity ... -
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 ...
