PERFORMANCE CAPTURE: À PROCURA DAS MELHORES TÉCNICAS E ESTÉTICAS NO CONTEXTO DA ANIMAÇÃO DIGITAL

This paper investigates realism in character computer animation, which triggered the development of new techniques and aesthetic in spectacular cinema and contemporary culture. With the advent of motion or performing capture, animation has made possible that virtual characters or digital creatures reach higher levels in emotional acting, taking place in virtual cinematic worlds or even special effects movies. This technology, when placed at the service of imagination and fantasy can provide new dimensions in character motion and communication. In this context, projects like Peter Jackson’s (2001) The Lord of the Rings, James Cameron’s Avatar (2009) and more recently Steven Spielberg’s Tintin (2011) demonstrate that motion technology is constantly evolving, and it represents a credible option to explore new techniques and aesthetic in contemporary animation.

Realism in Gameplay: Digital Fiction and Embodiment

In this article we argue that digital simulations promote and explore complex relations between the player and the machines cybernetic system with which it relates through gameplay, that is, the real application of tactics and strategies used by participants as they play the game. We plan to show that the realism of simulation, together with the merger of artificial objects with the real world, can generate interactive empathy between players and their avatars. In this text, we intend to explore augmented reality as a means to visualise interactive communication projects. With ARToolkit, Virtools and 3ds Max applications, we aim to show how to create a portable interactive platform that resorts to the environment and markers for constructing the games scenario. Many of the conventional functions of the human eye are being replaced by techniques where images do not position themselves in the traditional manner that we observe them (Crary, 1998), or in the way we perceive the real world. The digitalization of the real world to a new informational layer over objects, people or environments, needs to be processed and mediated by tools that amplify the natural human senses.

Pour une esthétique du cinéma transludique : figures du jeu vidéo et de l'animation dans le cinéma d'effets visuels du tournant du XXIe siècle

Cette thèse propose une analyse croisée du cinéma et du jeu vidéo sous un angle interdisciplinaire afin de montrer la réappropriation et le remédiatisation des structures narratives et formelles du jeu vidéo dans le cinéma d’effets visuels du tournant du XXIe siècle. Plus spécifiquement, la thèse porte sur l’analyse de trois figures majeures du jeu vidéo et de l’animation dans la trilogie Matrix (Larry et Andy Wachowski, 1999-2003), dans Avalon (Mamoru Oshii, 2001) et dans Kung-Fu Hustle (Stephen Chow, 2004). La première section de la thèse consiste en une mise en place théorique par la présentation de certains paramètres esthétiques du cinéma d’effets visuels et du jeu vidéo. Quelques réflexions préliminaires sur l’esthétique du cinéma d’effets visuels sont d’abord esquissées avant de présenter les principales relations transmédiales entre le cinéma et le jeu vidéo. Ensuite, c’est le cinéma transludique qui est défini alors que le terme découle de la synergie singulière entre le cinéma et le jeu vidéo. Puisque le cinéma transludique concerne spécifiquement la récupération de l’esthétique du jeu vidéo dans le cinéma contemporain, les prémisses d’une esthétique du jeu vidéo sont alors établies. Dans la deuxième section, ce sont les figures et sous-figures au cœur de cette réflexion qui sont développées, pour ensuite les appliquer aux films du corpus. La première figure à l’étude est celle de l’exploration, alors que l’analyse de la signification de cette figure dans la conception de jeu vidéo et dans les récits cinématographiques de science-fiction montre l’importance de la navigation comme expérience spatio-temporelle dans les univers virtuels. Ensuite, c’est l’utilisation récurrente de la figure vidéoludique du niveau (level) dans le cinéma hybride contemporain qui est soulignée, figure qui structure autant le récit que la forme représentationnelle des films transludiques. Enfin, la figure de la métamorphose, indissociable du cinéma d’animation, est étudiée afin de souligner l’importance de cette figure dans la création numérique et d’expliquer la transformation de l’image qui affecte le cinéma transludique, image qualifiée d’image-frontière.

Reuse of paths in light source animation

In this paper we extend the reuse of paths to the shot from a moving light source. In the classical algorithm new paths have to be cast from each new position of a light source. We show that we can reuse all paths for all positions, obtaining in this way a theoretical maximum speed-up equal to the average length of the shooting path

Metamorphic epiphany -- 3D animation

As far back as I can remember, I have always been interested in studio art. Whether it be painting, drawing, printmaking, or photography, it has consistently been a part of my life. Upon enrolling in Colby, I became interested in computers and decided to major my undergraduate college career in Computer Science. Not forgetting past interests, I continued my studio art education, taking several classes within the Art department. In due time, I began combining interests and began studying Computer Graphics and Design. With limited resources in this field at Colby, the majority of my computer graphic education and experience has been done on my own time apart from regular classroom work. As time progressed, so did my interests. Starting with simple image manipulation of digitally scanned photographs, I moved on to Web Page design, eventually leading to Desktop Publishing. Ultimately, I wanted to take a step further and expand my overall computer graphic knowledge by learning 3D modeling and animation. With even fewer resources in 3D animation at Colby, I perceived having trouble finding the information and tools I would need to gain the necessary skills for this new field. The Senior Scholars program gave me the opponunity to find and acquire the necessary tools to pursue my interest. This program also allowed me to devote the proper amount of time required for learning these new tools.

How children's television networks in the United States have adapted to the changing digital habits of their young audiences: A comparative analysis between the Disney Channel and Nickelodeon

In the contemporary societies, many children are drawn to digital media, using it in ways that were initially unfathomable. Changing digital habits among young children have been affiliated to the rapid development, witnessed in the technological field. Prevalently, new forms of technology are being developed and ingrained into young children’s day-to-day activities. The emergence of new forms of technology has in turn prompted significant changes in digital and media consumption particularly, among young children. Changes in media and digital consumption have in turn instigated linear transition in the analogue media industries. This has resulted in analogue media networks working towards digitalizing their industries in a manner that will befit changing digital habits among young children. This report aims at establishing and analyzing the different ways in which children’s digital habits have changed and revolutionized. To achieve this, the report will critically examine the existing scope of knowledge, with reference to changing digital habits among young audiences. Further, the report also aims at establishing the manner in which children television networks have adapted to the changing digital habits among young audiences. To achieve this, the report will focus on two children television networks, Disney channel, and Nickelodeon. After which, a comparative analysis will be conducted to establish the changes made by each of these television channels, with the aim of adapting to the new digital habits among children.

Quantitative fractography by digital image processing: NIH Image macro tools for stereo pair analysis and 3-D reconstruction

A set of NIH Image macro programs was developed to make qualitative and quantitative analyses from digital stereo pictures produced by scanning electron microscopes. These tools were designed for image alignment, anaglyph representation, animation, reconstruction of true elevation surfaces, reconstruction of elevation profiles, true-scale elevation mapping and, for the quantitative approach, surface area and roughness calculations. Limitations on time processing, scanning techniques and programming concepts are also discussed.

A Aplicação da Gestão de Projetos na Indústria Criativa - As Microempresas Nacionais de Animação Digital e Videojogos

Numa sociedade onde a inovação é uma pedra basilar para o sucesso das empresas, a criatividade tornou-se num dos mais valiosos ativos intangíveis e um fator chave decisivo para a generalidade das organizações. Segundo a consultora Augusto Mateus & Associados, com o evoluir da sociedade, todas as indústrias serão “culturais e criativas” (Augusto Mateus & Associados, 2010). As Indústrias Criativas têm vindo a assumir um papel cada vez mais relevante na sociedade atual sendo, nos dias de hoje, uma forte fonte de riqueza e emprego. Uma das áreas que mais se tem revelado através do seu rápido e notório crescimento é o sector da animação e dos videojogos, sendo este atualmente uma das indústrias mais valiosas do mundo. Porém, e apesar desta realidade, a atuação nesta indústria é muitas vezes conturbada, pois o sector caracteriza-se pela elevada competitividade, pelos altos custos de produção e pela grande incerteza. As dificuldades vivenciadas no sector levam a uma crescente preocupação pela procura de métodos de gestão sustentáveis, que permitam reduzir os riscos e a elevada taxa de incerteza. Dado que a maioria das empresas desta área está estruturada por projetos, um dos métodos de gestão mais aplicados é o modelo de gestão de projetos. Contudo, verifica-se que ainda existe uma evidente dificuldade na implementação deste modelo de gestão, em particular, nas empresas pequenas e de estrutura achatada, pois este torna-se muitas vezes burocrático, pesado e difícil de aplicar. Este estudo teve como objetivo principal compreender de forma as empresas nacionais de animação e videojogos gerem os seus projetos, sendo que, para este efeito, foram estudados três casos nacionais: a Nerd Monkeys, a Battlesheep e a Nebula Studios através de uma investigação exploratória dos métodos de gestão de projetos aplicados nas empresas de animação e videojogos. De modo a permitir a recolha da informação necessária para dar respostas aos objetivos definidos para a investigação, foi realizado um questionário e realizadas entrevistas semiestruturadas aos representantes das empresas em estudo. Nesta investigação foi possível aferir que apesar das empresas em estudo aplicarem alguns instrumentos da gestão de projetos, não aplicam nenhum método oficial de forma integral. Apesar de se verificar a utilização de algumas ferramentas de gestão de projetos, os sistemas aplicados dependem na maior parte dos casos do tipo de projeto desenvolvido, existindo algumas variações nos métodos utilizados. Em projetos de tempo mais reduzido e maior simplicidade, verifica-se que a gestão de projetos perde relevância, acabando por muitas vezes não ser aplicada.

Transition From Glass To Digital Slide Microscopy In The Teaching Of Oral Pathology In A Brazilian Dental School.

Several medical and dental schools have described their experience in the transition from conventional to digital microscopy in the teaching of general pathology and histology disciplines; however, this transitional process has scarcely been reported in the teaching of oral pathology. Therefore, the objective of the current study is to report the transition from conventional glass slide to virtual microscopy in oral pathology teaching, a unique experience in Latin America. An Aperio ScanScope® scanner was used to digitalize histological slides used in practical lectures of oral pathology. The challenges and benefits observed by the group of Professors from the Piracicaba Dental School (Brazil) are described and a questionnaire to evaluate the students' compliance to this new methodology was applied. An improvement in the classes was described by the Professors who mainly dealt with questions related to pathological changes instead of technical problems; also, a higher interaction with the students was described. The simplicity of the software used and the high quality of the virtual slides, requiring a smaller time to identify microscopic structures, were considered important for a better teaching process. Virtual microscopy used to teach oral pathology represents a useful educational methodology, with an excellent compliance of the dental students.

Avaliação de técnicas de classificação digital de imagens landsat em diferentes padrões de cobertura da terra em Rondônia

Remotely sensed imagery has been widely used for land use/cover classification thanks to the periodic data acquisition and the widespread use of digital image processing systems offering a wide range of classification algorithms. The aim of this work was to evaluate some of the most commonly used supervised and unsupervised classification algorithms under different landscape patterns found in Rondônia, including (1) areas of mid-size farms, (2) fish-bone settlements and (3) a gradient of forest and Cerrado (Brazilian savannah). Comparison with a reference map based on the kappa statistics resulted in good to superior indicators (best results - K-means: k=0.68; k=0.77; k=0.64 and MaxVer: k=0.71; k=0.89; k=0.70 respectively for three areas mentioned). Results show that choosing a specific algorithm requires to take into account both its capacity to discriminate among various spectral signatures under different landscape patterns as well as a cost/benefit analysis considering the different steps performed by the operator performing a land cover/use map. it is suggested that a more systematic assessment of several options of implementation of a specific project is needed prior to beginning a land use/cover mapping job.

Digital subtraction radiographic analysis of the combination of bioabsorbable membrane and bovine morphogenetic protein pool in human periodontal infrabony defects

OBJECTIVES: This study assessed the bone density gain and its relationship with the periodontal clinical parameters in a case series of a regenerative therapy procedure. MATERIAL AND METHODS: Using a split-mouth study design, 10 pairs of infrabony defects from 15 patients were treated with a pool of bovine bone morphogenetic proteins associated with collagen membrane (test sites) or collagen membrane only (control sites). The periodontal healing was clinically and radiographically monitored for six months. Standardized pre-surgical and 6-month postoperative radiographs were digitized for digital subtraction analysis, which showed relative bone density gain in both groups of 0.034 ± 0.423 and 0.105 ± 0.423 in the test and control group, respectively (p>0.05). RESULTS: As regards the area size of bone density change, the influence of the therapy was detected in 2.5 mm² in the test group and 2 mm² in the control group (p>0.05). Additionally, no correlation was observed between the favorable clinical results and the bone density gain measured by digital subtraction radiography (p>0.05). CONCLUSIONS: The findings of this study suggest that the clinical benefit of the regenerative therapy observed did not come with significant bone density gains. Long-term evaluation may lead to a different conclusions.

Evaluation of the maxillary premolar roots dissociation using radiographic holders with conventional and digital radiography

This in vivo study evaluated the dissociation quality of maxillary premolar roots combining variations of vertical and horizontal angulations by using X-ray holders (Rinn -XCP), and made a comparison between two types of intraoral radiography systems - conventional film (Kodak Insight, Rochester, USA) and digital radiography (Kodak RVG 6100, Kodak, Rochester, USA). The study sample was comprised of 20 patients with a total of 20 maxillary premolars that were radiographed, using the paralleling angle technique (GP), with a 20º variation of the horizontal angle (GM) and 25º variation of the horizontal angle combined with 15º vertical angle (GMV). Each image was independently analyzed by two experienced examiners. These examiners assigned a score to the diagnostic capability of root dissociation and the measurement of the distance between the apexes. Statistical data was derived using the Wilcoxon Signed Rank test, Friedman and T test. The means of the measured distances between buccal and lingual root apexes were greater for the GMV, which ranged from 2.3 mm to 3.3 mm. A statistically significant difference was found between GM and GMV when compared to GP with p < 0.01. An established best diagnostic dissociation roots image was found in the GMV. These results support the use of the anterior X-ray holders which offer a better combined deviation (GMV) to dissociate maxillary premolar roots in both radiography systems.
