kDet: Parallel Constant Time Collision Detection for Polygonal Objects
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We define a novel geometric predicate and a class of objects that enables us to prove a linear bound on the number of intersecting polygon pairs for colliding 3D objects in that class. Our predicate is relevant both in ...
Computational Light Painting Using a Virtual Exposure
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Light painting is an artform where a light source is moved during a long-exposure shot, creating trails resembling a stroke on a canvas. It is very difficult to perform because the light source needs to be moved at the ...
Simulation-Ready Hair Capture
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Physical simulation has long been the approach of choice for generating realistic hair animations in CG. A constant drawback of simulation, however, is the necessity to manually set the physical parameters of the simulation ...
Interactive Modeling and Authoring of Climbing Plants
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We present a novel system for the interactive modeling of developmental climbing plants with an emphasis on efficient control and plausible physics response. A plant is represented by a set of connected anisotropic particles ...
Interactive Paper Tearing
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
We propose an efficient method to model paper tearing in the context of interactive modeling. The method uses geometrical information to automatically detect potential starting points of tears. We further introduce a new ...
Flow-Induced Inertial Steady Vector Field Topology
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
Traditionally, vector field visualization is concerned with 2D and 3D flows. Yet, many concepts can be extended to general dynamical systems, including the higher-dimensional problem of modeling the motion of finite-sized ...
Practical Capture and Reproduction of Phosphorescent Appearance
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
This paper proposes a pipeline to accurately acquire, efficiently reproduce and intuitively manipulate phosphorescent appearance. In contrast to common appearance models, a model of phosphorescence needs to account for ...
On Realism of Architectural Procedural Models
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
The goal of procedural modeling is to generate realistic content. The realism of this content is typically assessed by qualitatively evaluating a small number of results, or, less frequently, by conducting a user study. ...
Unbiased Light Transport Estimators for Inhomogeneous Participating Media
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
This paper presents a new stochastic particle model for efficient and unbiased Monte Carlo rendering of heterogeneous participating media. We randomly add and remove material particles to obtain a density with which free ...
EcoBrush: Interactive Control of Visually Consistent Large-Scale Ecosystems
(The Eurographics Association and John Wiley & Sons Ltd., 2017)
One challenge in portraying large-scale natural scenes in virtual environments is specifying the attributes of plants, such as species, size and placement, in a way that respects the features of natural ecosystems, while ...
