Selective Rasterized Ray-traced Reflections on the GPU
(The Eurographics Association, 2016)
Ray-tracing achieves impressive effects such as realistic reflections on complex surfaces but is also more computationally expensive than classic rasterization. Rasterized ray-tracing methods can accelerate ray-tracing by ...
Design and Fabrication of Grid-shells Mockups
(The Eurographics Association, 2016)
Statics Aware Voronoi Grid-shells have been recently introduced in the Architectural Geometry field. These are innovative gridshells endowed with a polygonal topology, whose geometry is structurally optimized by means of ...
MLCut: Exploring Multi-Level Cuts in Dendrograms for Biological Data
(The Eurographics Association, 2016)
Choosing a single similarity threshold for cutting dendrograms is not sufficient for performing hierarchical clustering analysis of heterogeneous data sets. In addition, alternative automated or semi-automated methods that ...
Selective BRDFs for High Fidelity Rendering
(The Eurographics Association, 2016)
High fidelity rendering systems rely on accurate material representations to produce a realistic visual appearance. However, these accurate models can be slow to evaluate. This work presents an approach for approximating ...
Low Cost Handheld 3D Scanning for Architectural Elements Acquisition
(The Eurographics Association, 2016)
3D scanning has gone a long way since its first appearance in cultural heritage digitization and modeling. In the recent years some new low cost, fast, accurate emerging technologies are flooding the market. Envisioning ...
Mobile Multiview Diffuse Texture Extraction
(The Eurographics Association, 2015)
This paper presents a novel method for diffuse texture extraction from a set of multiview images. We address the problem of specularities removal by pixel value minimization across multiple automatically aligned input ...
Deployment of Volume Rendering Interactive Visualizations in Web Platforms With Intersected 3D Geometry
(The Eurographics Association, 2016)
Volume rendering is a visualization technique focused in volumetric datasets, which requires a great amount of computational power and memory resources. This situation is even more severe when HTML5 and WebGL implementations ...
Ordering Triangles in Triangulated Terrains Over Regular Grids
(The Eurographics Association, 2016)
In this work we report on a set of rules to visit triangles in triangulated height fields defined over regular grids in a back-to- front order with respect to an arbitrary viewpoint. With the viewpoint, we associate an ...
Anisotropic MatCap: Easy Capture and Reproduction of Anisotropic Materials
(The Eurographics Association, 2016)
We propose Anisotropic MatCap, a simple data structure based on a small volumetric texture that is able to represent, under a fixed lighting, the behavior of anisotropic materials. The data structure is designed to allow ...
3D Digital Imaging for Knowledge Dissemination of Greek Archaic Statuary
(The Eurographics Association, 2016)
This paper aims, using a research exercise, to verify the association between two Greek sculptures collected at different times: the head of a boy collected in the Chalcidian colony of Leontinoi in southeastern Sicily, ...
