The Technology pages cover different topics related to new developments in Information technologies, Virtual Reality, Robotics, Artificial Intelligence and other fields of technology.

Mar-06 Necuse Nanoespacio Custom Search.

Recently, the research department at Nanoespacio, has published a new tool, for the search and research of information through the net, its name is Necuse Nanoespacio Custom Search.

The key facts of this new tool is that it uses self developed Artificial Intelligence algorithms to optimize the process of search, and to provide the definitive tool for personalized internet search. meaning that it will match the results to exactly what you want to find.

You can have further information and demo download at

Will the U3D format be the ultimate interchange document for 3D models and worlds? , It looks like it will be, but we have seen many other 3D file types in the previous years.

A lot of time passed since the beginning of file types that allow you to communicate a 3D scene to the world. In fact most of the existing file types are proprietary of a software brand, and most of the cases there is no interactivity behind, just the definition of a 3D scene or object.

Some of this file types are:

3DS MAX® [.3ds and .prj]
3D GameStudio™ [.mdl]
Maya™ [.obj]
AC3D [.ac]
Cinema 4D® [.c4d]
DirectX® [.x]
Quake™ Formats [.mdx]
Lightwave® [.lwo and .lws]
Microstation DGN® [.dgn]
Moray UDO INC [.udo]
Movie BYU [.byu]
OpenFlight® [.flt]
Power Render Pro [.pro]
Polygon PLY [.ply]
quick3D® [.q3o and .q3s]
Renderman® [.rib]
RenderWare® [.rwx]
Stereo-CAD 3D [.3d2]
Softimage XSI® [.xsi]
Stereolithography STL [.stl]
Truespace® [.cob and .scn]
Visualization ToolKit [.vtk]
WorldToolKit [.nff]

And some more.

The first truly international format for exchange 3D scenes and worlds was the VRML, where in addition to the definition of the object or world allows you to define a behavior of the scene and includes some ways of interaction with it. Since it appears in 1996 it was like the PDF of the 3d formats and it gains momentum in the previous years, but it does not truly become a big standard and now its almost forgotten.

Next to that arrives formats like JAVA 3d, X3D or WEB 3D and others.

But now the format that seems to become the truly standard is the UNIVERSAL 3D, recently Adobe announces that in next acrobat version will be implemented compatibility with U3D format.

In the previous years a lot of companies join together to build this format through the "3D Industry Forum" :

ADL Co-Labs
Adobe Systems Inc.
The Boeing Company
Dassault Systemes
UGS PLM Solutions
Fraunhofer Institute
Intel Corporation
Mental Images
Mercury Computer Systems Inc. (TGS)
Parallel Graphics
Parametric Technology Corporation
Right Hemisphere
Science Applications International Corporation
SGDL Systems
Solid Works
Tech Soft America

Maybe this is the final interchange 3D format. Time will tell.

Wireless Technologies.

Were ever you are, connection to a any technological device is now possible , the world is now interconnected through the new digital revolution, where almost everything can be connected to something. Also a lot a new technologies made this possible in almost every were.

In essence we want to reach the information we need no matter were we are. In this new kind of communication there are a few elements:

-The beginning of the communication: the starting device of the connection: Pc, laptop, TabletPC,PDA, Phone, TV, other...

-Is this device also the communication device or we need an other for this purpose? We need a phone, Bluetooth device, network card, 802.11 and others, or is embedded in the device.

-What is the medium of the communication and protocols used? Gsm,Gprs,umts, lmds, satellite, etc...

-Elements in he middle of the communication: routers, commutation centers and other "in the middle" devices.

There are some other devices, protocols and interfaces for trying to "guaranty" the security of the data transmissions.

For the final purposes of the wireless communications we are in need of miniaturization of: send and receive devices and also data processors, Actually this technology already exists, we have the technology to get wireless to every were and to every thing, but the field to work in is the production cost reduction of this devices and the commercialization to make it profitable.

The times for example were the clothes we wear get a microprocessor and a communication device without increasing weight or size aren't far away.

For example the iButton® is a microchip in a 16mm JAVA enabled device :

Words about Computer Security.

Actually there is a paradigm in Computer security followed by the continuous technological evolution, for example the wireless systems as they are more popular they reach higher levels of insecurity at the same time.
Also the use of Satellite connections, optic fiber networks and other high end technology are introducing more variables to the complex computer security or system security formula.

Authentication through PKI, smartcards or biometrics systems try win the battle for the stealth of the identity through Internet and other networks.

Billions of security attacks, or hacker related attacks around the world are confirmed through the use of automated hacking tools, exposing millions of servers and computers. Also the security flaws inherent to ALL the software, most of them by human mistakes.

The Growing wireless and Satellite market like Wi-Fi, LMDS, Bluetooth, Wireless USB, Laptop, TabletPcs, PocketPcs and other PDAs with Internet Wireless connections or mobile phones. Also come with inherent system security flaws and exploits to be used by the attackers.

The Cyber-War in this new century used by countries or crime organizations is also a huge silent battle to be fight and the govern control of the communications with new internet laws limiting the expansion of the cyber world.

Present and Future of the Virtual Reality.

Virtual Reality at the turn of the year 2003 has a well defined history, and some of us have to write the future of the technology behind the Virtual Reality and the uses of it.
Actually the term Virtual Reality is used for designing an environment or device that "transport" us to other reality different than the actual one, there are several hardware devices used to do that:
- VR Head Mounted Displays ( HMDs )
- VR globes and other VR aptics
- VR suites
- Multi user VR Projection devices with or without glasses
- 3D flat panels
- High end 3D capable computer system
Also we need a VR World and software for moving the world.

The Future must be written, but the gaming industry and the investments in 3D visualization systems is an essential role in this future, also the investigation of the 3D Holograms could make my term "VR Room" a more real thing, also the growing augmented reality were we mix part of the real world with part of the virtual world, also olfactory systems.

I will try to show in these pages all the advances, my own research in this Technology and Others
