Comparative Visualization of FEM-Based Cutting Simulations in a Virtual Environment

Fritz Klocke & Andreas M. Straube
As one of the final steps in the industrial manufacturing chain, machining operations require significant economic consideration. At this stage, design components have already passed through several steps of this value-added manufacturing process. Industrial companies today are using Finite Element Simulations to optimize manufacturing processes, such as mechanical cutting. In order to obtain an increased understanding of the cutting process, several simulations with different input parameters are performed. A new method for comparing these results...

Enhanced Reconstruction of Architectural Wall Surfaces for 3D Building Models

Georgios-Tsampikos Michailidis & Renato Pajarola
The reconstruction of architectural structures from 3D building models is a challenging task and a lot of research has been done in recent years. However, most of this work is focused mainly on reconstructing accurately the architectural shape of interiors rather than the fine architectural details, such as the wall elements (e.g. windows and doors). We focus specifically on this problem and propose a method that extends current solutions to reconstruct accurately severely occluded wall...

Social Dining Experience using Mixed Reality for Older Adults

Jonathon Derek Hart, Gun A. Lee, Ashleigh E. Smith, Melissa Hull, Matthew T. Haren, Catherine Paquet, Julie-Ann Hill, Zack Lomax, Travis Ashworth & Ross T. Smith
This project investigates a novel method of engaging older adults in meaningful mealtime social interactions through the use of Mixed Reality technology. We propose a novel dining system that aims to facilitate interpersonal interactions and enhance meal consumption in socially isolated older adults. We created a prototype which allowed the target audience to test and discuss our concept so we can iteratively improve a user oriented design.

One-step Compact Skeletonization

Bastien Durix, Geraldine Morin, Sylvie Chambon, Jean-Luc Mari & Kathryn Leonard
Computing a skeleton for a discretized boundary typically produces a noisy output, with a skeletal branch produced for each boundary pixel. A simplification step often follows to reduce these noisy branches. As a result, generating a clean skeleton is usually a 2-step process. In this article, we propose a skeletonization process that produces a clean skeleton in the first step, avoiding the creation of branches due to noise. The resulting skeleton compares favorably with the...

An Interactive Tool for Modeling Ancient Masonry Buildings

Josep Lluis Fita, Gonzalo Besuievsky & Gustavo Patow
We present a new pipeline of an interactive tool that combines procedural modeling of ancient masonry buildings with structural simulation. The tool has been designed for taking an input geometry of an ancient building and re-meshing it into a suitable mesh with a low quad density. Then, it creates the brick outlines on the mesh and adds the brick volumes for structural simulation. The tool was designed and built on a set of off-the-shelf tools....

Parallel Architecture of an Interactive Scientific Visualisation System for Large Datasets

Sascha Schneider, Thorsten May & Michael Schmidt
In this paper we describe a further development state of our system which is able to compute actual scientific and realistic visualization methods in parallel. This paper is related to the basic work we presented in one of our previous articles 18. Our system is capable to integrate easily in modern VR renderers like for example Open Inventor 19, Coin 4 and OpenSG 5. Our approach is designed for processing large datasets which usually are...

Modeling Detailed Cloud Scene from Multi-source Images

Yunchi Cen, Xiaohui Liang, Junping Chen, Bailin Yang & Frederick W. B. Li
Realistic cloud is essential for enhancing the quality of computer graphics applications, such as flight simulation. Data-driven method is an effective way in cloud modeling, but existing methods typically only utilize one data source as input. For example, natural images are usually used to model small-scale cloud with details, and satellite images and WRF data are used to model large scale cloud without details. To construct large-scale cloud scene with details, we propose a novel...

Topology-Based Visualization of Time-Dependent 2D Vector Fields

Xavier Tricoche, Gerik Scheuermann & Hans Hagen
Topology-based methods have been successfully applied to the visualization of instantaneous planar vector fields. In this paper, we present the topology-based visualization of time-dependent 2D flows. Our method tracks critical points over time precisely. The detection and classification of bifurcations delivers the topological structure of time dependent vector fields. This offers a general framework for the qualitative analysis and visualization of parameterdependent 2D vector fields.

Computer Generation of Filmic Discourse from a Cognitive/Affective Perspective

John Bateman, Marc Christie, Roberto Ranon, Remi Ronfard & Tim Smith
In this position paper, we argue that advances in intelligent cinematography require better models of the multimodal structure of filmic discourse, and of the inferences made by an audience while films are being watched. Such questions have been addressed by film scholars and cognitive scientists in the past, but their models have not so far had sufficient impact on the intelligent cinematography community. In the future, this community should become more interested in understanding how...

A Guided Spatial Transformer Network for Histology Cell Differentiation

Marc Aubreville, Maximilian Krappmann, Christof Bertram, Robert Klopfleisch & Andreas Maier
Identification and counting of cells and mitotic figures is a standard task in diagnostic histopathology. Due to the large overall cell count on histological slides and the potential sparse prevalence of some relevant cell types or mitotic figures, retrieving annotation data for sufficient statistics is a tedious task and prone to a significant error in assessment. Automatic classification and segmentation is a classic task in digital pathology, yet it is not solved to a sufficient...

Interactive HDR Environment Map Capturing on Mobile Devices

Peter Kán
Real world illumination, captured by digitizing devices, is beneficial to solve many problems in computer graphics. Therefore, practical methods for capturing this illumination are of high interest. In this paper, we present a novel method for capturing environmental illumination by a mobile device. Our method is highly practical as it requires only a consumer mobile phone and the result can be instantly used for rendering or material estimation.We capture the real light in high dynamic...
