Vs Iris Diaphragm in photography

diaphragm

The human eye is capable of modifying its geometry to suit the lighting conditions. The iris is responsible for limiting the amount of light reaching our retina.

In photography there is a mechanical device called the diaphragm that functions iris. By combining the speed diaphragm shutter opening, obtain a depth of field.

3D Animation, Examples: Árbol de navidad [ Blogs experimental ] [ Blender ]

Christmas Tree

Let's see how to model with Blender is a small tree which has served to make the Christmas card presented in the first image.

We use a model similar to that used to create the Christmas tinsel, based on the concept of incorporating Blender hair.

Metric geometry : Pythagorean Theorem

Pythagoras

The metric geometry is based on the well-known theorem of Pythagoras, to set the metric relationship between the sides of a right triangle.
The concept of the Euclidean space as it adopts in its definition of distance, and geometric relations derived are paramount.

Wallpaper: Christmas 2011 (II) : Tinsel and bright balls [Imagen 1280×1024]

ESPUMILLON_navidad_2_150

A new wallpaper to use in the upcoming Christmas season and decorate your computer, made from the same scene in Blender we used for the above image: Tinsel and balls.

We performed a zoom to center the pattern on one of the christmas balls, obtaining a more homogeneous color distribution.

Graphical Programming: Double buffering : Draw in the background [JAVA]

doublebuffer

When creating the animation engine we have seen that the screen refresh flicker occurs undesirable. This effect is due to the time required to erase the image and generate a new updated, result of animate objects.

One technique to avoid this is called double buffering or “doublebuffered”

ESPUMILLON_150

A wallpaper made for use in the upcoming Christmas season and decorate your computer. In this case the image shows a bright tinsel (silver) surrounded by three spheres faceteadas with reflection effect. A composition modeled and rendered with Blender animation software. (View Christmas Tinsel)

Reflections of two cubes [ Wallpaper ]

Mirrored cube

Two concentric cubes with high reflectivity can form an image of great interest.
The scene was rendered with editing software, Blender modeling and animation 2.5 reflection indices value 20 for each cube and four point lighting, a white light, and one for each of the basic components of the RGB format.

The beauty of pollination [ TED ] [ Video ]

polinización_gota_agua

Louie Schwartzberg told us about the dependence we have on each other in one of those wonderful talks we see in TED , The talk was accompanied with beautiful images captured with high-speed cameras: The hidden beauty of pollination Pollination: it’s vital to life on Earth, but largely unseen by the human eye…. (leer más)

Graphical Programming: Animated Graphics Engine [JAVA]

motor_animación

After defining a first interface for drawing graphic objects in JAVA, we will implement animation graphics engine that allows us to manage the dynamics of the application and, later, add user interaction. El motor se encargará de llamar a las funciones que animan a cada uno de los objetos gráficos de la base… (leer más)
