The results of the inclusion of Virtual Reality in the production line of an Industry Joalheira in the state of Bahia, a case study which was conducted in the elevenmonth period by a Startup consisting of two professional Designers and one Information Technology, between the years of 2008 and 2009. The production flow of this jewelery factory was losses due to continuous communication difficulties...
This work aims to present a methodology of communication between a criminal database and a virtual environment for forensic study, using a proprietary software and a virtual reality prototype, in order to support forensic science activities. The objective is to assist the forensic professional offering the use of criminal investigation resources inside a crime scene simulation, with sensations of...
La lechería es muy importante para la economía uruguaya, por esta razón, interesa realizar investigaciones en esta área. Este trabajo comprendió la incorporación de tecnologías en sistemas lecheros para realizar estimaciones de disponibilidad de forraje. Particularmente, se estimó la disponibilidad de forraje en un potrero mediante el procesamiento de imágenes georeferenciadas de las pasturas, las...
The paper is devoted to modeling of single-layer garments as developable median surfaces, modeled in the form of a thin supple shell. The products are modeled in Maple 9.5 and Embarcadero RAD Studio. The modelling of conical skirts considering seams is performed to demonstrate the space form of garments in the gravity field of elastic materials. Also the product aeroman is modelled which brings the...
The emerging of BIM (Building Information Modeling) techniques will change traditional procedures of design and maintenance for electric substations. In addition, Computational Holography, supported by wearable computers, has the potential to allow simultaneous engineering work, based on mixed reality and computer vision capabilities. It is believed that this set of tools will increase engineering...
One difficulty of teaching in mathematics is to present abstract mathematical concepts or laws to students in a simple visual way to promote students' understanding and mastery. Traditionally mathematical teachers tried to explain abstract mathematical concepts and formulas by means of some simple teaching tools and some mathematical models presented by some mathematical software, such as Matlab,...
The visual simulation system which the docking process of replenishment at sea is constructed based on MultiGen Creator and Vega Prime. In a bid to modeling and driving of the visual simulation, a large number of the real-time data should be transformed for simulation in which the entire process of replenishment at sea. According to the complicated power and movement state of the docking mechanism...
The preservation of the sites, monuments and other spaces, cultural heritage of the Humanity, has been one of the areas of greater use of computer graphics. This paper presents a methodology of expeditious and low-cost work aimed at virtual recreation of these historical spaces, which, through their availability on the web, allows its analysis and study by experts, as well as their access to the public,...
New challenges and demands on software engineering education are presented by rapid changes and increased complexity of software systems. This paper presents the VisAr3D environment that has been developed as an innovative proposal to be introduced in the classroom to provide a 3D visualization of UML models. The user is invited to intuitively understand the model elements in this 3D environment....
A common workflow for visualization designers begins with a generative tool, like D3 or Processing, to create the initial visualization; and proceeds to a drawing tool, like Adobe Illustrator or Inkscape, for editing and cleaning. Unfortunately, this is typically a one-way process: once a visualization is exported from the generative tool into a drawing tool, it is difficult to make further, data-driven...
Summarized the mainly algorithms of terrain three-dimensional visualization in virtual reality, for the large-scale terrain data organization in three-dimensional virtual war zone simulation, analyzed the characteristic of change of scene, according to motion regulation and idea of layer and block, presented the organize principle of external static data and terrain blocks index regulation, for the...
Digital images obtained through medical imaging techniques are viewed using different visualization applications (methods). Also with the help of these applications, the three dimensional (3D) models of the images are created. Usually, the visualization and modelling processes are executed by medical staff, using general purpose applications. Via the same applications operation planning is made, after...
This paper builds on the authors' previous work with Augmented Reality (AR) technology as a tool to enhance traditional visualizations and facilitate the understanding of complex information. In this paper, we expand our previous work with AR technology by focusing on the process of creating custom content. Based on users' feedback, we describe and compare various strategies to create 3D models from...
Technology trends and market changes force modern manufacturing companies to employ complex, standalone mechatronic components for automating their production. The complexity of mechatronic components induces adverse effects on their corrective maintenance. Handling downtime of these components requires knowledge of system composition, effect of external and internal disturbances on the component...
This paper introduces a software development kit (SDK) to provide IT developers and medical community a platform to build new simulation technologies for surgery training. There is described a formal model for simulation objects, scenes and scenarios representation and a software solution for objects interaction modeling and surgery scene simulating. The results are illustrated by the simulation suite...
Vection is the illusion of self-motion, usually induced by a visual stimulus. It is important in virtual reality because inducing it in motion simulations can lead to improved experiences. We examine linear and circular vection in commodity level head-mounted displays. We compare the experience of circular vection induced through a real world stimulus, an optokinetic drum, with that experienced through...
A major cause for a lack in acceptance of today's interdisciplinary modeling approaches is the immense difference in abstraction between engineers' mental models and the available systems modeling languages [1]. Especially mechanical engineers, who use graphical representations like sketches and 3D CAD models, struggle with so called “graphical modeling languages” such as SysML [1][2]. These models...
Building architects, but also civil or mechanical engineers often build from their designs physical 3D models for a better presentation, comprehension, and communication among stakeholders. Software engineers usually create visualizations of their software designs as digital objects to be presented on a screen only. 3D software visualization metaphors, such as the software city metaphor, provide a...
This article gives a brief description of the problem you have in the development of spatial skills, and the use of new practices based on implementation of ICT (Information and Communication) in Higher Education. Initially the main types of intelligence described in the literature and the different spatial ability are described. Subsequently a dissertation about the usefulness of the development...
An application for evacuation simulation using computational resources may help previewing situations, flows, conflicts, and behaviours that may only happen in a real danger situation. This kind of application enables the execution of several pre-defined scenarios at any time, without the expensive and complex allocation of real people. This paper proposes an emergency simulation system on oil platforms...
