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 ...
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 ...
Infinite Resolution Textures
(The Eurographics Association, 2016)
We propose a new texture sampling approach that preserves crisp silhouette edges when magnifying during close-up viewing, and benefits from image pre-filtering when minifying for viewing at farther distances. During a ...
Mathematical Analysis on Affine Maps for 2D Shape Interpolation
(The Eurographics Association, 2012)
This paper gives a simple mathematical framework for 2D shape interpolation methods that preserve rigidity. An interpolation technique in this framework works for given the source and target 2D shapes, which are compatibly ...
Curve Density Estimates
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this work, we present a technique based on kernel density estimation for rendering smooth curves. With this approach, we produce uncluttered and expressive pictures, revealing frequency information about one, or, multiple ...
A Shader Framework for Rapid Prototyping of GPU-Based Volume Rendering
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
In this paper, we present a rapid prototyping framework for GPU-based volume rendering. Therefore, we propose a dynamic shader pipeline based on the SuperShader concept and illustrate the design decisions. Also, important ...
