C++ Compile Time Polymorphism for Ray Tracing

Stefan Zellmann & Ulrich Lang
Reducing the amount of conditional branching instructions in innermost loops is crucial for high performance code on contemporary hardware architectures. In the context of ray tracing algorithms, typical examples for branching in inner loops are the decisions what type of primitive a ray should be tested against for intersection, or which BRDF implementation should be evaluated at a point of intersection. Runtime polymorphism, which is often used in those cases, can lead to highly expressive...

PBmapclust: Mapping and Clustering the Protein Conformational Space Using a Structural Alphabet

Iyanar Vetrivel, Lionel Hoffmann, Sean Guegan, Bernard Offmann & Adele D. Laurent
Analyzing the data from molecular dynamics simulation of biological macromolecules like proteins is challenging. We propose a simple tool called PBmapclust that is based on a well established structural alphabet called Protein blocks (PB). PBs help in tracing the trajectory of the protein backbone by categorizing it into 16 distinct structural states. PBmapclust provides a time vs. amino acid residue plot that is color coded to match each of the PBs. Color changes correspond to...

Animal gaits from video

Laurent Favreau, Lionel Reveret, Christine Depraz & Marie-Paule Cani
We present a method for animating 3D models of animals from existing live video sequences such as wild life documentaries. Videos are first segmented into binary images on which Principal Component Analysis (PCA) is applied. The time-varying coordinates of the images in the PCA space are then used to generate 3D animation. This is done through interpolation with Radial Basis Functions (RBF) of 3D pose examples associated with a small set of key-images extracted from...

An Art-based Approach to Visual Analytics

Gunjan Sehgal & Geetika Sharma
In this paper, we propose an art-based approach to visual analytics.We argue that while artistic data visualizations have mainly been designed to communicate the artist's message, certain artistic styles can be very effective in exploratory data analysis as well and data visualizations can benefit from more than just the aesthetics inspired by art. We use the ancient Warli style of tribal paintings, found in western India to demonstrate the use of artistic styles for visual...

Effects of Embodiment on Generic and Content-Specific Intelligent Virtual Agents as Exhibition Guides

Susanne Schmidt, Gerd Bruder & Frank Steinicke
Intelligent Virtual Agents (IVAs) received enormous attention in recent years due to significant improvements in voice communication technologies and the convergence of different research fields such as Machine Learning, Internet of Things, and Virtual Reality (VR). Interactive conversational IVAs can appear in different forms such as voice-only or with embodied audio-visual representations showing, for example, human-like contextually related or generic three-dimensional bodies. In this paper, we analyzed the benefits of different forms of virtual agents...

Egocentric Normalization of Kinematic Path

Eray Molla & Ronan Boulic
We focus on retargetting the class of movements involving self-interactions onto characters with different size and proportion. Such postures may produce self-collisions and/or alter the intended semantics. We introduce a technique to normalize the spatial relationship vectors between the body parts of the source character. This allows for morphological adaptation of these vectors onto the target characters, hence preserving the semantics in postures with and without body-contact.

A Novel Approach for Cooperative Motion Capture (COMOCAP)

Gregory Welch, Tianren Wang, Gary Bishop & Gerd Bruder
Conventional motion capture (MOCAP) systems, e.g., optical systems, typically perform well for one person, but less so for multiple people in close proximity. Measurement quality can decline with distance, and even drop out as source/sensor components are occluded by nearby people. Furthermore, conventional optical MOCAP systems estimate body posture using a global estimation approach employing cameras that are fixed in the environment, typically at a distance such that one person or object can easily occlude...

Assessing Graphic Designers' Learning Style Profile to Improve Creative Coding Courses

Stig Møller Hansen
This study aimed at assessing graphic design students' preferences for learning to help design school educators teaching Creative Coding programming courses adapt their teaching style to account for the way their students learn. The Felder- Soloman Index of Learning Styles (ILS©) was administered to 77 bachelor-level graphic design students. Compared to students in technical fields, the graphic design students differed by being considerably more intuitive, with an increased preference for active and visual learning. Based...

Judgment Error in Pie Chart Variations

Robert Kosara & Drew Skau
Pie charts and their variants are prevalent in business settings and many other uses, even if they are not popular with the academic community. In a recent study, we found that contrary to general belief, there is no clear evidence that these charts are read based on the central angle. Instead, area and arc length appear to be at least equally important. In this paper, we build on that study to test several pie chart...
