Sony Realtime Projection Mapping “Great films fill room”

filled room

The immersive virtual reality systems are in a stage of development which ensures a promising future in the world of entertainment, Training and Simulation.

The use of multimedia devices and positioning technologies integration, interaction and projection are leading to interesting demonstrations of the power of these technologies.

In memoriam : Jean Giraud : Moebius

moebius

A mosaic with some of the most iconic images of the great comic artist Jean Giraud, Moebius, died at the 73 age. A master draftsman who illustrated our dreams with his fictional characters set in worlds past and future. Adios Mr. “Provides”, we have your work and your memory, your… (leer más)

Whodunnit? Test percepción

perception

These days I'm doing a scientific experiment about perception; a colleague has sent me this video that shows that sometimes (mostly) not find what you are looking for but can not have it in front.

A funny video that makes us perceive clearly how difficult it is to appreciate our surroundings in detail.

Mapas de normales : bump mapping : Mapeado topológico

texture_bump_mapping_botones_smooth_150

In computer animation the number of surfaces in the scene greatly influences the time of computation (rendering) de la SMA.

A technique for simulating on a flat surface roughness is called “Bump mapping”; comprises applying a texture to the surface to modify the direction of the normal to the same, influencing the calculation of shading algorithms (Shading) applied during image rendering, without changing the topology.

Figure impossible

The so-called impossible figures can be a pleasant pastime in the study of geometry.
Its construction using a modeling tool such as Blender, is an interesting exercise in application of the concepts studied in the prospects.

Debetener What form and what point of view is to be used to create the misleading appearance? An optical illusion can fool our senses.

Brain III : Brain – toon [ Imagen ][ Wallpaper ]

brain_4_thumb

A new rendering of the 3D model of the brain made with Blender animation software.
En este caso se han definido superficies transparentes y se ha utilizado un shader (render) clásico de los dibujos animados (Toon) que utiliza una rampa de colores para diferenciar claramente las zonas con sombra de las zonas claras o con brillo.

Metric geometry : Angles on the circumference : Central and inscribed

angulo_inscrito

In metric geometry measuring two concepts on which is based its axiomatic model: measures linear and angular measurements.
The linear measurement is based on the Pythagorean theorem and the relationship between these measures in Thales.
The angular measurement from the relations expressed in a circle and with the above can describe the magnitude of geometric figures.

3D Animation, Simulation : Clothing: main variables [Blogs experimental] [Blender]

Blender possible to create surfaces that behave like clothing. The simulation model is based on mass-spring techniques for use in computer animation, elastic bodies for defining.

The cloth simulation module has control variables used to adjust the properties of the various tissues to be emulated.

The light of the sunset [Imagen] [Wallpaper]

ocaso_red_thumb

We have seen how the sunset light, with sunset, appear reddish by diffusion in the atmosphere.

The different frequencies of light, within the visible spectrum, undergo variations in its trajectory to collide with the suspended particles in the atmosphere are. This effect in computer animation is included in the concept of participating media.
