Desarrollo de un personaje animado 2D a 3D

En esta memoria expongo mi trabajo de fin de grado de tipología práctica, consistente en la elaboración de los gráficos completos en un nivel de cortometraje. La meta de este proyecto pertenece al aprendizaje en la transición de un personaje de dos dimensiones a tres. Tras la elaboración de un cortometraje de animación 2D en colaboración con cuatro estudiantes de la Facultad de Bellas Artes de la misma Universidad, imaginé como podría ser la imagen de la misma traducida a un nuevo formato que actualmente se lleva a cabo en varias empresas. Debido a las características de producción del proyecto (recursos y trabajo individual) asumí el diseño y elaboración del personaje, incluyendo diseño visual (concept art), modelado 3d, materiales, texturas y animación. El cortometraje cuyo título es “Deblai” es un cortometraje cómico. Ambientado en un diseño inspirado en la famosa serie animada Ed, Edd n Eddy, con un estilo de animación clásica inspirada en la serie Tom and Jerry: el personaje tiene una persecución cómica y desenfrenada con la “inspiración”, recibiendo duros y exagerados mamporros. En cuanto a la apariencia del personaje, opté por un modelado de media poligonización y una visualización (render) con aspecto de dibujo animado (toon render, cell shading), tanto por cuestiones estéticas como de resultado de movimiento (no estamos hablando sobre un juego para dispositivos de bajo rendimiento). Se ha realizado un estudio del contexto y los subgéneros con los que guarda relación. Como resultado práctico muestro parte de la producción del cortometraje en 2D, y el modelado del personaje, así como su posterior rigging y animación.Herein, I present my final degree project, consisting of the design and development of complete graphics in a short film level. The goal of this project consists of learning the process of transition from a character in two dimensions to three. After developing a 2D animation short film in collaboration with four art students from the Faculty of Fine Arts at the same university, I imagined how the image of it could be translated into a new format that is currently conducted by several companies. Because of the production characteristics of the project (resources and individual work), I took on the design and development of the character, including visual design (concept art), 3D modelling, materials, textures and animation. The story titled "Deblai" is a comedy short film. It is set in a design inspired by the famous Ed, Edd n Eddy cartoon series and a classic animation style inspired by The Tom and Jerry Show design: the character has a comic and rampant persecution with “inspiration”, getting a hard and exaggerated smite. Regarding its appearance, I was decided to use middle-poly modelling and a cartoonish visual aspect (toon render, cell shading), both because of aesthetic reasons as for instance the result of movement (we're not talking about a game on low performance devices). In this report, a survey of the context of as well as of the subgenres has been conducted with which it relates. As a practical result, here it is my part of the production of the film in 2D, and character modelling as well as its rigging and animation later.Delgado Alarcón, C. (2014).

La narrativa en experiencias de realidad mixta para desarrollar cultura de prevención de riesgos laborales en construcción

La creciente digitalización en la construcción, especialmente impulsada a través del Modelado de información de construcción (Building Information Modeling, BIM) pero que también incluye monitorización, visión por computador y virtualización, entre otras, conduce a la reflexión y renovación de los procesos para la prevención de riesgos laborales (PRL). La tríada Tecnología-Procesos-Personas permite anticipar y diseñar de forma holística esta transformación digital que se viene produciendo en la industria. Como ejemplo, se está intensificando la trazabilidad de las actividades cotidianas para el estudio de nuevos procedimientos encaminados a erradicar los accidentes. Se busca optimizar procesos, como las trayectorias de vehículos y personas, el horario previsto para ciertas tareas simultáneas, con el fin de evitar la probabilidad de colisión entre maquinaria y trabajadores. A pesar de ello, en los últimos años el índice de incidencia de siniestros no solo no experimenta mejora, sino que muestra un cierto repunte, ya sea porque estas innovaciones no se están desplegando debidamente, porque se requiera de mayor madurez tecnológica o por no atender debidamente el comportamiento humano, clave en los índices de accidentabilidad. Así, más allá de la tecnología, es crucial el desarrollo de una cultura de prevención. En particular, el uso de la realidad mixta se plantea como un canal que permite al trabajador interiorizar la prevención como pilar fundamental no solo para su supervivencia, sino también para su calidad de vida sin secuelas debidas a accidentes o a malos hábitos laborales. La realidad virtual y aumentada permite situar al usuario en una gran variedad de escenarios y circunstancias peligrosas, prácticamente ilimitada, tales como laderas deslizantes, maquinaria descontrolada o clima adverso, de acuerdo con el tipo de obra y criterio del experto prevencionista. Existe aún un paso más allá del realismo de los escenarios virtuales: el mensaje a transmitir. Con estas experiencias se puede facilitar la transferencia de conocimiento entre trabajadores, por ejemplo, entre un minero a punto de jubilarse que relata su angustia ante una caída desde una gran altura y un joven que termina de incorporarse y que solo conoce peligros desde la teoría. Este enfoque permite estudiar el rol de las emociones y factores culturales como determinantes del comportamiento de las personas. El uso de la narrativa (storytelling) como medio bien conocido del cine y teatro para transmitir sentimientos a las audiencias, puede ayudar a profundizar en la concienciación de los usuarios que están experimentando los contenidos en primera persona (storyliving) y que tengan un significado emocional más allá del contenido teórico sobre los protocolos PRL. Disminuir el índice de accidentabilidad implica aprender a identificar los riesgos, saber valorarlos en su gravedad y estar capacitados para reaccionar ante ellos para erradicarlos o, cuando menos, para minimizar su probabilidad de ocurrencia. El objetivo es pasar de un sistema preventivo que descansa sobre todo en la legislación y supervisión a otro basado en la cultura, evolucionar de sistemas de vigilancia al desarrollo de narrativas convincentes, donde el factor humano ocupa un lugar central

Results of the COVID-19 mental health international for the general population (COMET-G) study.

INTRODUCTION: There are few published empirical data on the effects of COVID-19 on mental health, and until now, there is no large international study. MATERIAL AND METHODS: During the COVID-19 pandemic, an online questionnaire gathered data from 55,589 participants from 40 countries (64.85% females aged 35.80 ± 13.61; 34.05% males aged 34.90±13.29 and 1.10% other aged 31.64±13.15). Distress and probable depression were identified with the use of a previously developed cut-off and algorithm respectively. STATISTICAL ANALYSIS: Descriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses and Factorial Analysis of Variance (ANOVA) tested relations among variables. RESULTS: Probable depression was detected in 17.80% and distress in 16.71%. A significant percentage reported a deterioration in mental state, family dynamics and everyday lifestyle. Persons with a history of mental disorders had higher rates of current depression (31.82% vs. 13.07%). At least half of participants were accepting (at least to a moderate degree) a non-bizarre conspiracy. The highest Relative Risk (RR) to develop depression was associated with history of Bipolar disorder and self-harm/attempts (RR = 5.88). Suicidality was not increased in persons without a history of any mental disorder. Based on these results a model was developed. CONCLUSIONS: The final model revealed multiple vulnerabilities and an interplay leading from simple anxiety to probable depression and suicidality through distress. This could be of practical utility since many of these factors are modifiable. Future research and interventions should specifically focus on them

Libertad confinada: relatos de la pandemia

¿Cómo se experimenta un objeto desconocido, no percep-tible y peligroso? Esta es la pregunta abordada por las fotografías e historias contenidas en este libro. Pregunta extraña en la medida que se enuncia una vez se ha producido la experiencia, pues dicho objeto se conoce más por sus efectos que por su pura presencia. El Virus, objeto espectral, se encuentra en cada fotografía como manifestación, como ensamblado de cuerpos y cosas, de emociones y pensamientos. Sabemos de él por lo que hace con nosotros, por la forma como nos obliga a modificar nuestras pautas, nuestro acervo emocional, nuestra manera de conectarnos con el mundo

Results of the COVID-19 mental health international for the health professionals (COMET-HP) study: depression, suicidal tendencies and conspiracism.

IntroductionThe current study aimed to investigate the rates of anxiety, clinical depression, and suicidality and their changes in health professionals during the COVID-19 outbreak.Materials and methodsThe data came from the larger COMET-G study. The study sample includes 12,792 health professionals from 40 countries (62.40% women aged 39.76 ± 11.70; 36.81% men aged 35.91 ± 11.00 and 0.78% non-binary gender aged 35.15 ± 13.03). Distress and clinical depression were identified with the use of a previously developed cut-off and algorithm, respectively.Statistical analysisDescriptive statistics were calculated. Chi-square tests, multiple forward stepwise linear regression analyses, and Factorial Analysis of Variance (ANOVA) tested relations among variables.ResultsClinical depression was detected in 13.16% with male doctors and 'non-binary genders' having the lowest rates (7.89 and 5.88% respectively) and 'non-binary gender' nurses and administrative staff had the highest (37.50%); distress was present in 15.19%. A significant percentage reported a deterioration in mental state, family dynamics, and everyday lifestyle. Persons with a history of mental disorders had higher rates of current depression (24.64% vs. 9.62%; p < 0.0001). Suicidal tendencies were at least doubled in terms of RASS scores. Approximately one-third of participants were accepting (at least to a moderate degree) a non-bizarre conspiracy. The highest Relative Risk (RR) to develop clinical depression was associated with a history of Bipolar disorder (RR = 4.23).ConclusionsThe current study reported findings in health care professionals similar in magnitude and quality to those reported earlier in the general population although rates of clinical depression, suicidal tendencies, and adherence to conspiracy theories were much lower. However, the general model of factors interplay seems to be the same and this could be of practical utility since many of these factors are modifiable

The effect of different degrees of lockdown and self-identified gender on anxiety, depression and suicidality during the COVID-19 pandemic: Data from the international COMET-G study.

IntroductionDuring the COVID-19 pandemic various degrees of lockdown were applied by countries around the world. It is considered that such measures have an adverse effect on mental health but the relationship of measure intensity with the mental health effect has not been thoroughly studied. Here we report data from the larger COMET-G study pertaining to this question.Material and methodsDuring the COVID-19 pandemic, data were gathered with an online questionnaire from 55,589 participants from 40 countries (64.85% females aged 35.80 ± 13.61; 34.05% males aged 34.90±13.29 and 1.10% other aged 31.64±13.15). Anxiety was measured with the STAI, depression with the CES-D and suicidality with the RASS. Distress and probable depression were identified with the use of a previously developed cut-off and algorithm respectively.Statistical analysisIt included the calculation of Relative Risk (RR), Factorial ANOVA and Multiple backwards stepwise linear regression analysis RESULTS: Approximately two-thirds were currently living under significant restrictions due to lockdown. For both males and females the risk to develop clinical depression correlated significantly with each and every level of increasing lockdown degree (RR 1.72 and 1.90 respectively). The combined lockdown and psychiatric history increased RR to 6.88 The overall relationship of lockdown with severity of depression, though significant was small.ConclusionsThe current study is the first which reports an almost linear relationship between lockdown degree and effect in mental health. Our findings, support previous suggestions concerning the need for a proactive targeted intervention to protect mental health more specifically in vulnerable groups
