PRODUCTION PROCESS Perspective: A volume in the style projector Star Wars 22/Jul/02 The National Institute of Advanced Industrial Science and Technology of Japan (AIST) has developed a laser projector that creates real images in the air pointing to points in space and create plasma emissions from oxygen and nitrogen present. The laser heat expands the air, producing a sound resembling small explosions. Still far from StarWars, but equally impressive. (Ciudad Internet) You can see the future, but represent volumetric 3D images (such as holograms) that produce a sense of reality never attained so far.His appearance (a crystal ball mounted on a small platform) seems part of a Volumetric Display art parody cheap for a visionary, rather than what it really is: a volumetric display, the latest in graphical representation, which allows to visualize objects three dimensions but adding the sense of volume. The simplest, inside the ball 60 centimeters in diameter can represent any 3D creation, even with movement, and observe it as if it were a real object from any viewing angle. Until recently, this type of equipment was part of the fantasy of films like The War of the galaxies, where a kind of intercom with holographic interference pops up a three-dimensional image of the speaker volume galactic shift.In this case, the reality will twist the arm back to technology with this project called Perspecta, created by the firm Actuality Systems. The most interesting feature of this display is that it can represent any 3D object made with the usual techniques. Just a matter of connecting to a PC so that the object in question is represented by him, besides the bread The difference is striking: more realism by having a 3D object, you can not compare his picture on a screen against thepossibility of having a display 360 degrees horizontally and 270 vertically (since its base is slightly Abridged). While it is the rookie in this kind of device is the first to achieve rates of more than acceptable definition.The resolution quality of these teams is quantified in a unit called voxel (volumetric pixel), of which this system achieves the 768×768 pixels of 198 levels of 8 colors, giving a total of 116 million voxels. Unlike other similar, using a complex system of mirrors and beams of light bouncing between them, the performance of Vista is quite simple to explain: use a white plastic disc measuring 25 cm in diameter rotating at 700 RPM and three projectors emitting conventional LCD alternately flashes images on this disk, which ends reflecting inside the ball creating the feeling volume. Most of the work of creating this illusion has the image processor that runs the complex mathematical algorithms designed by their creators. This display is adapted to any PC or SCSI port running Windows 2000 or Linux. Being based on Open GL standards, work with most 3D design software.The image size can reach 25 The equipment is tested in some companies, such as a pharmaceutical drug design, but its usefulness has a huge field in multiple fields such as medical, surgical, scientific research, geology, architecture, CAD, and why not, entertainment. For now both waste of technology (see creativity as) is only affordable to such companies, not end users: 50 thousand U.S. dollars The estimated sale price are obviously eloquent in all dimensions. They produce three-dimensional images that float in the air Japanese scientists have built a device that projects three-dimensional images in real air.
