BubpTop is a prototype 3D desktop, as you will see from the video is truly amazing what you can do with documents on your desktop. If you are a fan of "creative disorder" can spread wildly your PDF files on your desktop literally throwing, or you can neatly stack all your Word documents with just a flick of the mouse ... well you can do all (or almost) what you can do with spreadsheets of your real desk.

Definition associated with the video taken from Wikipedia:
The 3D computer graphics is a branch of computer graphics that is based on the development virtual models in 3D by a computer. It is used along with computer animation in the production of visual images for cinema or television, video games, engineering, commercial or scientific use. The term can also refer to images produced by the same method.
The 3D computer graphics is basically the science, the study and the method of projection of the mathematical representation of three-dimensional objects using two-dimensional image through the use of techniques such as perspective and shading (shading) to simulate the perception of these objects by the human eye. Each 3D system must provide two elements: a method of describing the same 3D system ("scene"), composed of mathematical representations of three-dimensional objects, such role models, and a mechanism for producing a 2D image from the scene, said " renderer. "
3D Models:
Three-dimensional objects can be represented by simple equations operating on a three-dimensional Cartesian reference system, for example, the equation x ² + y ² + z ² = r ² is perfect for a sphere of radius r. Although such simple equations may seem restrictive, the set of feasible objects is extended with a technique called constructive solid geometry (CSG, constructive solid geometry), which combines solid objects (such as cubes, spheres, cylinders, etc..) To form more complex objects through Boolean operations (union, intersection and difference): for example, a pipe can be represented as the difference between two cylinders of different diameters. Even
However, this technique is not sufficient to describe with simple equations a large number of objects, so it is not commonly used. To model curved surfaces in an arbitrary manner you can use the patch, or extension of the spline that approximate continuous curves, the three dimensions. The patches are more commonly used in practice based on spline NURBS.
The use of mathematical equations as well as the use of these requires a large amount of computing power, and are therefore not practical for real-time applications such as video games and simulations. A more efficient technique, but allows a lower level of detail, to model objects is to highlight some points of the object, without information on the trace between them. The result is called a polygonal model. This presents "facets" rather than curves, but rendering techniques have been developed to overcome this loss of data.
surface of a polygonal model with no information on the curvature can still be refined by algorithmic perfectly curved surfaces: this technique is called subdivision surfaces ", because the surface is divided by an iterative process in most areas, more and more small loyal to the interpolated curve and which make one surface more smooth.
