Groups at the NSF, NIST, U. Florida and elsewhere are creating networked 3d worlds with open standards.
Original Post: Paul Fishwick: Caves - a cheaper version ===================================================== | | I am seeking solutions to the problem of viewing | | VRML worlds on a NAVE. | | The overview of the NAVE can be found at | | http://www.digitalworlds.ufl.edu/research/nave/default.asp | | There is one host PC that sends position and orientation | information (of the avatar) to each of 3 PCs, each of | which projects an image onto a panel. | | With 3 panels, one obtains a panoramic view. | | The only problem that we have now is that the | default software to make this work revolves | around a package called "SVE" (which uses OpenGL). | | We'd like to make the NAVE available to the | display of VRML (and X3D). This would open the | NAVE to many more applications. | http://www.web3d.org/www-vrml/hypermail/2002/01/0423.html Paul, please meet Vincent Stanford. Your tax dollars have helped Mr. Stanford build a networked conferencing system at the NIST that your system would benefit from, if you used compatible open standards. one proposed solution ... | Assuming the Cortona VRML Player ActiveX | | control can give you such notifications, | a scenario could be ... | | I haven't yet integrated them with VRML, | | but there should be no need if you can script | them from Cortona. | | I'm also thinking of making a Blaxxun deviceSensor | out of them ... | http://www.web3d.org/www-vrml/hypermail/2002/01/0424.html It would seem open standards and portable solutions would preferable, and please note the NSF and NIST has funded research ( see above ) that are portable and some or all of the software is available for free and a lot of work has been done successfully with Java, and this includes MPEG-4 predecessors with Web3d's H-Anim Avatars. | 'Smart' Video Conferencing with open standards (Nist) | | Government Computer News ( Today, Feb. 12, 2002 ): | ------------------------ | | NIST delves into pervasive computing | ------------------------------------ | | Pervasive-computing systems could make | conference rooms brainy, according to the | Smart Space Laboratory researchers at the | National Institute of Standards and Technology. | ... | The meeting room generates about 1G per minute | or 60G per hour of data from five steerable | Sony EVI-D30 videoconferencing cameras ... | [and] about 200 low-cost ... microphones ... | The open-source clustering software can harness | up to 24 computers, Stanford said. | | NIST has made the source code and | documentation available for download at http://www.nist.gov/smartspace/toolChest/nsfs http://www.gcn.com/21_3/tech-report/17856-1.html | http://archives.java.sun.com/cgi-bin/wa?A2=ind0202&L=java3d-interest&P=R31446 | Cluster for Immersive VR (slashdot.org) | --------------------------( today: Dec. 18, 2001 ) | | | | the folks down at the University of Illinois ... | | created a 6-sided CAVE like system called ALICE. | | | | But, instead of running it off of a SGI Onyx, | | they've developed a distributed environment for | | visualization called Syzygy. [souce code avialable] | | | http://slashdot.org/articles/01/12/18/0424225.shtml | http://www.web3d.org/www-vrml/hypermail/2001/12/0155.html | NIST Smart Space 'Smart' Video Conferencing ( Source Code Available ) | ------------------------------------------- http://www.nist.gov/smartspace/toolChest/nsfs/#dataFlowDownload http://www.nist.gov/smartspace/toolChest/nsfs/dataFlow/NSFS_source-1.0.tgz http:toolChest/nsfs/dataFlow/NSFS_source-1.0.tgz | ( note: the above is a bad link from the above page ) | | The goals, techniques & technologies of this government effort | is complementary to the VRML - Web Animation - Java3d work | of these groups, and the source code is avaiable. ;^) | | It's a C / Linux implementation, uses 'open standards', | and thus would intergegrate and work with ... VRML & Java3d. | http://archives.java.sun.com/cgi-bin/wa?A2=ind0202&L=java3d-interest&P=R31446 Human Animation with Open Standards: H-Anim & VRML --------------------------------------------------- http://www.frontiernet.net/~imaging/java3d_and_vrml.html http://www.frontiernet.net/~imaging/H-Anim_Avatars.html NIST Human Models Animated with Java3d & the old way: ---------------------------------------------------- http://ovrt.nist.gov/home.html http://ovrt.nist.gov/projects/mfg/3int/3int.wrl http://www.frontiernet.net/~imaging/sc_manufacturing_simulation.jpg http://www.frontiernet.net/~imaging/games_with_java3d.html -- The above shows to do Web Animation with VRML & Java3d.

Please help! | http://www.web3d.org/www-vrml/hypermail/2001/12/0186.html Networked 3d solutions include games: | Game Sessions at JavaOne 2002 | | This year's JavaOne will see the addition of | 3 sessions around game development. ... | | The addition of Java game discussions to | the formal schedule underscores Sun Microsystems | increasing focus on the games industry overall. | | The sessions for JavaOne are: | | * TS--3199 - Building a High-Performance Multiplayer Internet Games ... | * BUS-3354 - Java Technology 2001: The Year of the Games | * TS--1243 - Java Game Profile Update | * TS--3347 - Developing Games for JavaTM 2 Platform, | Micro Edition (J2METM) Technology-Enabled Mobile Devices | http://www.javagaming.org/ and research .. | Our prototype, consisting of a series of linked | desktops, is designed to facilitate collaboration | among users who are exploring time series of climatic | data for a large drainage basin. The exploration | involves interaction with shared dynamic | (animated and interactive) displays. | | The prototype is constructed from a set of | Java/Java3D tools. These include VisAD, | a DEM viewing module that works with VisAD, | and our own extensions for data queries and | networking. | http://www.geovista.psu.edu/research/collaborativevisualization/index.html and military applications ... | The concept of 'Network-Centric Warfare' is | a derivative of 'network-centric computing'. | | The evolution ... has been largely enabled | by recent key developments in information technology. | | Some of the most important developments in information | technology include Hyper Text Markup Language (HTML), | web-browsers, TCP/IP, and the Java computing architecture. | | These developments make it much easier for computers with | different operating systems to interact with each other. | http://www.dtic.mil/jcs/j6/education/warfare.html Open standards with Web3'ds VRML based H-Anim Avatars and standard networking technologies have been used sucessfully for games, research, education, and military applications and our tax dollars have funded systems that are availbe to us from the NIST & NSF. | H-Anim and MPEG-4 are dependendent on | implementing technologies, of which Java3d | is one of the best available to us and both | H-Anim and MPEG-4 have been held back | by misperceptions, false statements, and | unethical conduct. | | The VRML Loaders from Sun provided | | the highest level of functionality for | loading VRML files into Java3d ... | | -- and still do -- | | ~~ please ~~ correct me ... if any other | VRML loader is more capable for loading | VRML into Java3d and rendering it with | animation. | http://www.web3d.org/WorkingGroups/web3d-mpeg/hypermail/2001/0159.html Networked 3d virtual worlds have been implemented with open standards -- you paid for some the work -- the NSF, NIST and our military has funded some of the research and development and a lot of free software, including source is available to you. Using non-standard, non-portable, unreliable, virus prone, closed solutions like ActiveX would be absolutely daffy. -- Paul, Java Developer & Web Animator. --------------------------------------- "Imaging the Imagined: Modeling with Math & Keyboard" =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA3D-INTEREST".
