Photo-Guided Exploration of Volume Data Features
(The Eurographics Association, 2017)
In this work, we pose the question of whether, by considering qualitative information such as a sample target image as input, one can produce a rendered image of scientific data that is similar to the target. The algorithm ...
Interactive Exploration of Dissipation Element Geometry
(The Eurographics Association, 2017)
Dissipation elements (DE) define a geometrical structure for the analysis of small-scale turbulence. Existing analyses based on DEs focus on a statistical treatment of large populations of DEs. In this paper, we propose a ...
Rapid k-d Tree Construction for Sparse Volume Data
(The Eurographics Association, 2018)
While k-d trees are known to be effective for spatial indexing of sparse 3-D volume data, full reconstruction, e.g. due to changes to the alpha transfer function during rendering, is usually a costly operation with this ...
An Interpolation Scheme for VDVP Lagrangian Basis Flows
(The Eurographics Association, 2019)
Using the Eulerian paradigm, accurate flow visualization of 3D time-varying data requires a high temporal resolution resulting in large storage requirements. The Lagrangian paradigm has proven to be a viable in situ-based ...
Efficient Point Merging Using Data Parallel Techniques
(The Eurographics Association, 2019)
We study the problem of merging three-dimensional points that are nearby or coincident. We introduce a fast, efficient approach that uses data parallel techniques for execution in various shared-memory environments. Our ...
Statistical Analysis of Parallel Data Uploading using OpenGL
(The Eurographics Association, 2019)
Modern real-time visualizations of large-scale datasets require constant high frame rates while their datasets might exceed the available graphics memory. This requires sophisticated upload strategies from host memory to ...
Effective Parallelization Strategies for Scalable, High-Performance Iterative Reconstruction
(The Eurographics Association, 2020)
Iterative reconstruction techniques in X-ray computed tomography converge to a result by successively refining increasingly accurate estimates. Compared to alternative approaches, iterative reconstruction imposes significant ...
High-Quality Rendering of Glyphs Using Hardware-Accelerated Ray Tracing
(The Eurographics Association, 2020)
Glyph rendering is an important scientific visualization technique for 3D, time-varying simulation data and for higherdimensional data in general. Though conceptually simple, there are several different challenges when ...
Fast Multi-View Rendering for Real-Time Applications
(The Eurographics Association, 2020)
Efficient rendering of multiple views can be a critical performance factor for real-time rendering applications. Generating more than one view multiplies the amount of rendered geometry, which can cause a huge performance ...
Scalable Parallel Flow Visualization Using 3D Line Integral Convolution for Large Scale Unstructured Simulation Data
(The Eurographics Association, 2019)
To address the need of highly efficient and scalable parallel flow visualization methods, we developed a flow visualization system for large unstructured simulation data using parallel 3D line integral convolution (LIC). ...
