Interactive Ray Tracing for Virtual TV Studio Applications

In the last years, the well known ray tracing algorithm gained new popularity with the introduction of interactive ray tracing methods. The high modularity and the ability to produce highly realistic images make ray tracing an attractive alternative to raster graphics hardware. Interactive ray tracing also proved its potential in the field of Mixed Reality rendering and provides novel methods for seamless integration of real and virtual content. Actor insertion methods, a subdomain of Mixed Reality and closely related to virtual television studio techniques, can use ray tracing for achieving high output quality in conjunction with appropriate visual cues like shadows and reflections at interactive frame rates. In this paper, we show how interactive ray tracing techniques can provide new ways of implementing virtual studio applications.

O aprimoramento de um software de estúdio virtual por meio de técnicas de matting digital e registro de objetos virtuais

A virtual studio system can use technologies as augmented reality and digital matting to decrease production costs at the same time it provides the same resources of a conventional studio. With this, it’s possible for the current studios, with low cost and using conventional devices, to create productions with greater image quality and effects. Some difficulties are recurrent in virtual studio applications that use augmented reality and digital matting. The virtual objects registration in augmented reality techniques suffer from problems caused by optical distortions in the camera, errors in the marker tracking system, lack of calibration on the equipments or on the environment (lighting, for example), or even by delays in the virtual objects display. On the other hand, the digital matting’s main problem is the real-time execution to preview the scene, which must have optimized processing speed at the same time while maintain the best image quality possible. Taking the given context into consideration, this work aims to give continuity to a virtual studio system called ARStudio, by enhancing digital matting, virtual objects registration and introducing a segmentation based on depth map, yet adding better control over functionalities previously implemented

Digital Illumination for Augmented Studios

Virtual studio technology plays an important role for modern television productions. Blue-screen matting is a common technique for integrating real actors or moderators into computer generated sceneries. Augmented reality offers the possibility to mix real and virtual in a more general context. This article proposes a new technological approach for combining real studio content with computergenerated information. Digital light projection allows a controlled spatial, temporal, chrominance and luminance modulation of illumination – opening new possibilities for TV studios.

Wildspace VR. Il wellness per le nuove generazioni - Studio su come la psicologia percettiva applicata alla Virtual Reality può migliorare gli effetti della Mindfulness

Dai recenti studi effettuati sulle nuove generazioni (Z e Alpha) è emerso che stress e ansia colpiscono di più i giovani che si trovano in queste fasce di età. Questa tesi, partendo dalle ricerche socio-culturali, vuole proporre una soluzione progettuale a questi problemi. Si vuole elaborare quindi un progetto sul benessere mentale attraverso la Mindfulness. Le nuove tecnologie emergenti, come ad esempio l’Extended reality, stanno trovando consenso tra le nuove generazioni. Per questo motivo è stata scelta questa tecnologia per erogare il contenuto del servizio. Si ipotizza di poter migliorare gli effetti della Mindfulness utilizzando la Psicologia Percettiva. Questo campo di studio consente di sfruttare l’alterazione della percezione nella Virtual Reality attraverso ‘Spatial Visualization’ e ‘Spatial Audio’. Queste ipotesi sono stata valutate attraverso uno studio indiretto del mercato del Wellness e consolidate attraverso una User Research. Dopo questa fase di ricerca si è valutata la strada progettuale comprendendo a fondo i bisogni del target: i giovani lavoratori. Sono stati utilizzati metodi di Design Thinking e Service Design per intraprendere il progetto, tenendo ben saldi i valori etici. Il progetto pensato, Wildspace VR, è un servizio per aziende che permette ai dipendenti di meditare con contenuti di Mindfulness in Realtà Virtuale. I contenuti proposti mirano a rispondere ai bisogni degli utenti elaborando per loro percorsi personalizzati. Le aziende traggono ricavo dal servizio avendo dipendenti profittevoli salvaguardando il loro stato di salute. L’obiettivo è aiutare i giovani lavoratori offrendogli la possibilità di praticare la Mindfulness dal luogo di lavoro grazie alla Realtà Virtuale, dando loro uno strumento per affrontare lo stress quotidiano in modo innovativo. Si è infine fatto un M.V.P. dell’esperienza, elaborando un prototipo Virtuale e stilando conclusioni ed idee per sviluppi futuri.

Studio e sviluppo di un motore a 2 tempi diesel veloce di nuova concezione per applicazioni automobilistiche

The Department of Mechanical and Civil Engineering (DIMeC) of the University of Modena and Reggio Emilia is developing a new type of small capacity HSDI 2-Stroke Diesel engine (called HSD2), featuring a specifically designed combustion system, aimed to reduce weight, size and manufacturing costs, and improving pollutant emissions at partial load. The present work is focused on the analysis of the combustion and the scavenging process, investigated by means of a version of the KIVA-3V code customized by the University of Chalmers and modified by DIMeC. The customization of the KIVA-3V code includes a detailed combustion chemistry approach, coupled with a comprehensive oxidation mechanism for diesel oil surrogate and the modeling of turbulence/chemistry interaction through the PaSR (Partially Stirred Reactor) model. A four stroke automobile Diesel engine featuring a very close bore size is taken as a reference, for both the numerical models calibration and for a comparison with the 2-Stroke engine. Analysis is carried out trough a comparison between HSD2 and FIAT 1300 MultiJet in several operating conditions, at full and partial load. Such a comparison clearly demonstrates the effectiveness of the two stroke concept in terms of emissions reduction and high power density. However, HSD2 is still a virtual engine, and experimental results are needed to assume the reliability of numerical results.

Metodi numerici per lo studio di centri di lavoro ad alta velocità

A Machining Centre is nowadays a complex mechanical, electronic, electrical system that needs integrated design capabilities which very often require a high time-consuming effort. Numerical techniques for designing and dimensioning the machine structure and components usually requires different knowledge according to the system that have to be designed. This Ph. D Thesis is related about the efforts of the Authors to develop a system that allows to perform the complete project of a new machine optimized in its dynamic behaviour. An integration of the different systems developed, each of which respond to specific necessities of designer, is here presented. In particular a dynamic analysis system, based on a lumped mass approach, that rapidly allows to setup the drives of the machine and an Integrated Dynamic Simulation System, based on a FEM approach, that permit a dynamic optimization, are shown. A multilevel Data Base, and an operator interface module provide to complete the designing platform. The proposed approach represents a significant step toward the virtual machining for the prediction of the quality of the worked surface.
