Hybrid-Treemap Layouting

Sebastian Hahn & Jürgen Döllner
This paper presents an approach for hybrid treemaps, which applies and combines several different layout principles within a single tree map in contrast to traditional treemap variants based on a single layout concept. To this end, we analyze shortcomings of state-of-the-art treemap algorithms such as Moore, Voronoi and Strip layouts. Based on a number of identified edge cases, we propose a combination of these different layout algorithms, individually selected for and applied on each sub...

Prometheus: Facial Modelling, Tracking and Puppetry

J.M. Thorne & D.J. Chatting
The Prometheus project sought to create a real-time production chain for 3D content. This paper summarises the techniques that were developed for facial modelling, tracking and puppetry. The process used for creating photo-realistic models from images of the face is discussed along with the creation of a real-time markerless facial feature tracker, highlighting the methods for extracting pose, detecting the shape of the mouth and interpreting the occurrence of skin wrinkling. The conversion of tracking...

Deployable 3D Linkages with Collision Avoidance

Changxi Zheng, Timothy Sun & Xiang Chen
We present a pipeline that allows ordinary users to create deployable scissor linkages in arbitrary 3D shapes, whose mechanisms are inspired by Hoberman's Sphere. From an arbitrary 3D model and a few user inputs, our method can generate a fabricable scissor linkage resembling that shape that aims to save as much space as possible in its most contracted state. Self-collisions are the primary obstacle in this goal, and these are not addressed in prior work....

Analysing Cinematography with Embedded Constrained Patterns

Hui-Yin Wu & Marc Christie
Cinematography carries messages on the plot, emotion, or more general feeling of the film. Yet cinematographic devices are often overlooked in existing approaches to film analysis. In this paper, we present Embedded Constrained Patterns (ECPs), a dedicated query language to search annotated film clips for sequences that fulfill complex stylistic constraints. ECPs are groups of framing and sequencing constraints defined using vocabulary in film textbooks. Using a set algorithm, all occurrences of the ECPs can...

Interactive Augmented Reality Techniques for Construction at a Distance of 3D Geometry

Wayne Piekarski & Bruce H. Thomas
This paper presents a series of new augmented reality user interaction techniques to support the capture and creation of 3D geometry of large outdoor structures, part of an overall concept we have named construction at a distance. We use information about the user’s physical presence, along with hand and head gestures, to allow the user to capture and create the geometry of objects that are orders of magnitude larger than themselves, with no prior information...

Evaluating Cognitive Load: Force-directed Layout vs. Chord Layout

Ricarda Moses, Shah Rukh Humayoun, Ragaad AlTarawneh & Achim Ebert
Understanding cognitive processes during the interaction with visualizations, specifically limitations of working memory, opens a new perspective on evaluations and encourages a more user-centric design approach. In a user study we evaluated two graph data visualization approaches (i.e., the force-directed layout and the Chord layout) using a cognitive load questionnaire to assess the three load types: intrinsic, extraneous, and germane load. Tasks were designed to encourage insight and sensemaking in the participants during the evaluation....

Scan4Reco: Towards the Digitized Conservation of Cultural Heritage Assets via Spatiotemporal (4D) Reconstruction and 3D Printing

Nikolaos Dimitriou, Anastasios Drosou & Dimitrios Tzovaras
The European Cultural Heritage includes a rich variety of cultural items and a significant amount of resources is devoted to their conservation and dissemination to the public. Living in the era of digitization, these efforts have been significantly facilitated by advances not only in traditional domains (e.g. material science, etc.), but also from more modern ones (i.e. 3D computer graphics & VR simulations). Within this context, the EU funded project Scan4Reco aims to offer low-cost...

Integrating Visualization Literacy into Computer Graphics Education Using the Example of Dear Data

Andrey Krekhov, Michael Michalski & Jens Krüger
The amount of visual communication we are facing is rapidly increasing, and skills to process, understand, and generate visual representations are in high demand. Especially students focusing on computer graphics and visualization can benefit from a more diverse education on visual literacy, as they often have to work on graphical representations for broad masses after their graduation. Our proposed teaching approach incorporates basic design thinking principles into traditional visualization and graphics education. Our course was...
