El educational system is to take cohetes. What the numbers say, level tests we make our students reflected in comparative studies, and international rankings of our universities. Me gustaría centrar el debate en un punto concreto que actualmente crea un importante desasosiego entre nuestros docentes universitarios: the access system… (leer más)
The Blue Brain Project aims molecular level simulation of the mammalian brain. In this first article outlines the main ideas and actors involved in the project. This initiative, supported by Big Blue (IBM) It focuses on Spain in the so-called Cajal Blue Brain (in honor of our… (leer más)
All that we have ever said that something is more difficult than squaring the circle. What does it mean? It is impossible. Squaring the circle is therefore not a difficult task, not impossible. The mathematical problem can be stated as: “Determining a square having the same area as a circle“ Esto… (leer más)

Fractals have been commonly known by its appearance or artistic expression. Benoît Mandelbrot defended its importance now begins to glimpse. Escher drew them from his imagination, without knowing complex equations representing.

The use of fractals in diversss disciplines, as generators of complex systems models, are an area of research ever more present.
An approach to fractal geometry can be easily performed by the Koch curve.
If any area of knowledge has been abused in contemporary education has been to “Graphic Expression“. Usually has taught in courses that have been termed pejoratively as “the marias“; The meaning is associated with its facility to be approved by the students. Drawing, plastic expression, arts education, etc., son nombres comúnmente utilizados… (leer más)
The realization of complex scenarios and games with high realism demands the use of sophisticated techniques that avoid saturating the bandwidth available on graphics cards.
Reducing the number of polygons to represent one of the priority objectives for improving performance.
Una técnica que permite representar un objeto con un número de polígonos que depende de la distancia del objeto al punto de observación se denomina LOD (Level Of Detail)
En este artículo profundizaremos en estos conceptos que permiten optimizar la representación de complejas escenas con gran realismo.
Definition of Virtual Reality (RV) What is Virtual Reality? How can we define something that in itself is contradictory?: ¿The Virtual Real? Un paradigma que evoluciona desde su nacimiento incorporando nuevos recursos y nuevos interrogantes asociados a ellos no tiene fácil conceptualización y, accordingly, its definition is subject to further revisions. Existen multitud de… (leer más)

Besides their use for composing and generating for illustration purposes, can be used for other tasks, as the analysis of an illusion, a medical image etc.. El mundo de la imagen nos ofrece curiosidades que afectan al… (leer más)
The current lineup of the characters autonomous avatars, to generate dynamic virtual worlds, every day, represent everyday reality or fantasy with great fidelity and realism. Structured models to implement autonomous characters recreation simulations and virtual worlds ( game programming, movies… ) they are based on different strategies… (leer más)
To create photorealistic images using different programming techniques, being “Raytracing” or “raytracing” one of the most interesting offering.
In this paper we introduce concepts necessary to understand how to generate one of these images, while this technique is presented by a sequence of “intermediate photos” that explain in detail the properties of synthetic lighting models.
