Asynchronous Implicit Backward Euler Integration
(The Eurographics Association, 2016)
In standard deformable object simulation in computer animation, all the mesh elements or vertices are timestepped synchronously, i.e., under the same timestep. Previous asynchronous methods have been largely limited to ...
Analytic Tangent Irradiance Environment Maps for Anisotropic Surfaces
(The Eurographics Association and Blackwell Publishing Ltd., 2012)
Environment-mapped rendering of Lambertian isotropic surfaces is common, and a popular technique is to use a quadratic spherical harmonic expansion. This compact irradiance map representation is widely adopted in interactive ...
Real-Time Rendering of Water Surfaces with Cartography-Oriented Design
(ACM, 2013)
More than 70 percent of the Earth's surface is covered by oceans, seas, and lakes, making water surfaces one of the primary elements in geospatial visualization. Traditional approaches in computer graphics simulate and ...
Interactive Rendering of Atmospheric Scattering Effects Using Graphics Hardware
(The Eurographics Association, 2002)
To create realistic images using computer graphics, an important element to consider is atmospheric scattering, that is, the phenomenon by which light is scattered by small particles in the air. This effect is the cause ...
Single-Pass Full-Screen Hardware Accelerated Antialiasing
(The Eurographics Association, 2000)
This paper describes a modified A-buffer algorithm and its hardware architecture for single-pass full-screen antialiasing. For storage and management of fragments, a dynamic memory management scheme, which can be efficiently ...
Efficient Stackless Hierarchy Traversal on GPUs with Backtracking in Constant Time
(The Eurographics Association, 2016)
The fastest acceleration schemes for ray tracing rely on traversing a bounding volume hierarchy (BVH) for efficient culling and use backtracking, which in the worst case may expose cost proportional to the depth of the ...
Prediction of Distributed Volume Visualization Performance to Support Render Hardware Acquisition
(The Eurographics Association, 2017)
We present our data-driven, neural network-based approach to predicting the performance of a distributed GPU volume renderer for supporting cluster equipment acquisition. On the basis of timing measurements from a single ...
Visualization-Guided Evaluation of Simulated Minimally Invasive Cancer Treatment
(The Eurographics Association, 2016)
We present a visualization application supporting interventional radiologists during analysis of simulated minimally invasive cancer treatment. The current clinical practice employs only rudimentary, manual measurement ...
Image Warping for a Painterly Effect
(The Eurographics Association, 2015)
We propose a two-stage approach to painterly rendering of photographs, where the image plane is first warped to produce a distorted or caricatured effect and then the resulting image is rendered with a painterly effect. ...
Mosaic Drawings and Cartograms
(The Eurographics Association and John Wiley & Sons Ltd., 2015)
Cartograms visualize quantitative data about a set of regions such as countries or states. There are several different types of cartograms and - for some - algorithms to automatically construct them exist. We focus on ...
