Introducción a Blender

El mundo de la animación 3D está en plena actualidad en este momento. Salas de cine, programas de televisión y la publicidad nos muestran constantemente personajes y objetos animados creados por ordenador. Son muchos los programas que pueden usarse para la realización de animación en 3D. En este proyecto vamos a centrarnos en Blender. Blender es un programa de animación y modelado que se puede obtener de manera gratuita por internet. Se trata de un programa de software libre, por lo que constantemente está siendo modificado gracias a la aportación de usuarios anónimos por internet. El objetivo de este proyecto es la creación de un corto de animación de un minuto de duración con Blender, para lo cual serán necesarias una serie de pautas iniciales sobre cómo funciona Blender y sus posibilidades. La primera parte de este proyecto es una guía básica sobre Blender y sus características. Capítulo a capítulo se irán describiendo la interfaz del programa y la creación de objetos (modelado, asignación de materiales y texturas) para luego aprender a animarlos y a visualizarlos como imágenes o video. La segunda parte se centra en el corto MOL. Creado a partir de los conocimientos adquiridos en la guía anterior, añadiendo en algunos casos, nuevas propiedades necesarias para su elaboración. Se describirán cada uno de los elementos y su creación. Esta guía pretende ser un referente para aquel que quiera introducirse en el mundo de la animación 3D con Blender. The world of 3D animation is a trending topic nowadays. Cinema, television and advertising constantly show us characters and animated objects created with computer graphics. There are many programs that can be used to perform 3D animations. In this project we will focus on Blender. Blender is a modeling and animation program that is available for free online. Blender is an open source program, so it is constantly being modified and improved by anonymous online users. The objective of this project is to create a one-minute animation short with Blender, for which we will require an initial set of guidelines on how Blender works and its possibilities. The first part of this project is a basic guide and will only cover basic features of Blender. In each chapter we will describe the interface and how to create objects (modeling, assigning materials and textures) and then we will learn to animate these objects and to display them as images or video. The second part focuses on the short film MOL. Created from the knowledge gained in the previous guide adding, in same cases, new properties necessary for its creation. We will describe each of the elements involved in the making of. This guide is intended to be a referent guide for anyone who wants to enter the world of 3D animation with Blender.

Subjective comparison of consumer television technologies for 3D visualization

This paper presents a comparison among different consumer 3D display technologies by means of a subjective assessment test. Therefore, four 55-in displays have been considered: one autostereoscopic display, one stereoscopic with polarized passive glasses, and two with active shutter glasses. In addition, a high-quality 3D video database has been used to show diverse material with both views in high definition. To carry out the test, standard recommendations have been followed considering also some modifications looking for a test environment more similar to real home viewing conditions, with the objective of obtaining more representative conclusions. Moreover, several perceptual factors have been considered to study the performance of the displays, such as picture quality, depth perception, and visual discomfort. The obtained results show interesting issues, like the performance improvement of active shutter glasses technology, the high performance of the polarized glasses technology in terms of quality and comfort, and the need of improvement of the autostereoscopic displays to complement the visual comfort to reach a global high-quality visual experience.
