A Practical and Efficient Approach for Correct Z-Pass Stencil Shadow Volumes
(The Eurographics Association, 2019)
Shadow volumes are a popular technique to compute pixel-accurate hard shadows in 3D scenes. Many variants exist that trade off accuracy and efficiency. In this work, we present an artifact-free, efficient, and easy-to-implement ...
Wide BVH Traversal with a Short Stack
(The Eurographics Association, 2019)
Compressed wide bounding volume hierarchies can significantly improve the performance of incoherent ray traversal, through a smaller working set of inner nodes and therefore a higher cache hit rate. While inner nodes in ...
Experiencing Art by Means of 3D Printed Replicas: Enriching the Interpretation of Pot Oiseau
(The Eurographics Association, 2019)
Digitally fabricated artefacts or 3D replicas have the potential to enrich the interpretation of cultural assets by enhancing visitors' engagement with collections. However, it is still not well understood how replicas ...
Approximate Reconstruction of 3D Scenes From Bas-Reliefs
(The Eurographics Association, 2019)
For thousands of years, bas-reliefs have been used to depict scenes of everyday life, mythology and historic events. Yet, the precise geometry of those scenes remains difficult to interpret and reconstruct. Over the past ...
End-to-end Color 3D Reproduction of Cultural Heritage Artifacts: Roseninsel Replicas
(The Eurographics Association, 2019)
Planning exhibitions of cultural artifacts is always challenging. Artifacts can be very sensitive to the environment and therefore their display can be risky. One way to circumvent this is to build replicas of these ...
Generating Playful Palettes from Images
(The Eurographics Association, 2019)
Playful Palettes are a recent innovation in how artists can mix, explore, and choose colors in a user interface that combines the benefits of a traditional media painter's palette with non-destructive capabilities of digital ...
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). ...
Fast Mesh Validation in Combustion Simulations through In-Situ Visualization
(The Eurographics Association, 2019)
In-situ visualization and analysis is a powerful concept that aims to give users the ability to process data while it is still resident in memory, thereby vastly reducing the amount of data left for post-hoc analysis. The ...
Stipple Removal in Extreme-tone Regions
(The Eurographics Association, 2019)
Conventional tone-preserving stippling struggles with extreme-tone regions. Dark regions require immense quantities of stipples, while light regions become littered with stipples that are distracting and, because of their ...
Irregular Pebble Mosaics with Sub-Pebble Detail
(The Eurographics Association, 2019)
Pebble mosaics convey images through an irregular tiling of rounded pebbles. Past work used relatively uniform tile sizes. We show how to create detailed representations of input photographs in a pebble mosaic style; we ...
