Out-of-Core Construction of Sparse Voxel Octrees
(ACM, 2013)
Voxel-based rendering has recently received significant attention due to its potential in the context of efficiently rendering massively large and highly detailed scenes. Unfortunately, few or no scenes are available in ...
Automatic Shader Level of Detail
(The Eurographics Association, 2003)
Current graphics hardware can render procedurally shaded objects in real-time. However, due to resource and performance limitations, interactive shaders can not yet approach the complexity of shaders written for film ...
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 ...
High-Quality Pre-lntegrated Volume Rendering
(The Eurographics Association, 2001)
We introduce a novel texture-based volume rendering approach that achieves the image quality of the best post-shading approaches with far less slices. It is suitable for new flexible consumer graphics hardware and provides ...
Towards Hardware Implementation Of Loop Subdivision
(The Eurographics Association, 2000)
We present a novel algorithm to evaluate and render Loop subdivision surfaces. The algorithm exploits the fact that Loop subdivision surfaces are piecewise polynomial and uses the forward difference technique for efficiently ...
Towards Interactive Bump Mapping with Anisotropic Shift-Variant BRDFs
(The Eurographics Association, 2000)
In this paper a technique is presented that combines interactive hardware accelerated bump mapping with shift-variant anisotropic reflectance models. An evolutionary path is shown how some simpler reflectance models can ...
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 Visual Analytics Approach for Peak-Preserving Prediction of Large Seasonal Time Series
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Time series prediction methods are used on a daily basis by analysts for making important decisions. Most of these methods use some variant of moving averages to reduce the number of data points before prediction. However, ...
Perlin Noise Pixel Shaders
(The Eurographics Association, 2001)
While working on a method for supporting real-time procedural solid texturing, we developed a general purpose multipass pixel shader to generate the Perlin noise function. We implemented this algorithm on SGI workstations ...
A User Study of Visualization Effectiveness Using EEG and Cognitive Load
(The Eurographics Association and Blackwell Publishing Ltd., 2011)
Effectively evaluating visualization techniques is a difficult task often assessed through feedback from user studies and expert evaluations. This work presents an alternative approach to visualization evaluation in which ...
