Program Overview
line
VR-Cloud ® is a consensus building solution which uses 3D and VR on a cloud server. With only internet access environment, even thin client would be able to operate the VR space by web browser. Android™ client is supported.
(Patent applied for data transmission technology "a3S" of VR-Cloud® [Application No. 2010-290022])


VR-Cloud® Collaboration
In addition to the Standard virsion, in the Collaboration version, the practical use of more advanced VR, such as "3D bulletin board function" and "Annotation function" etc. on Cloud is realized.
  • 3D bulltin board function : Creating discussion inside of VR space, display and replay
  • Annotation function : Creating and displaying the annotation such as a figure and text inside of VR space by a simple editor.

VR-Cloud® Standard
Original transmission technology "a3S (Anything as a Service)" is implmented, and the performance improved more than 4 times as much as the conventional ratio. Cloud typed VR application in new form by an original client.
  • Performance improved drastically with a3S transmission technology. 
  • Many simulation functions in UC-win/Road are available.

VR-Cloud® Flash Version
It's the system to execute UC-win/Road on server and to perform the remote control of VR space with Adobe Flash Player as the client software by using the plug-in. 

VR-Cloud® SDK
You can now develop a customized interface of your own using the AngelScript scripting language. An optimal GUI tailored to fit your application and needs can be offered.

a3s (Anything as a Service) SDK
This is a SDK (Software Development Kit) to create original cloud application. It is possible to create many different cloud-based applications and services by leveraging on the cloud server's hardware to transfer or to stream big volumed video or sound data to end-cleints. 

Rhino Plug-in
This plug-in is for displaying 3D models created by Rhinoceros 3D® (Robert McNeel & Associates http://www.en.la.mcneel.com/)

line
It's the system to execute UC-win/Road on server and to perform the remote control of VR space with Adobe Flash Player as the client software by using the plug-in. (Speed, latency, and functions are limited compared with Standard and Collaboration version.)
  • It's possiblle to publish the data created in UC-win/Road online and for general people to operate VR space and freely check the project by themselves.
  • Various interactive VR space, such as a run and a traffic simulation, is offered.

   VR-Cloud® SDK
Line

Thanks to the development of VR-Cloud® SDK, you can now develop a customized interface of your own using the AngelScript scripting language. An optimal GUI tailored to fit your application and needs can be offered.

There's more to come! After the release of the next version which is scheduled for July, VR-Cloud® SDK and UC-win/Road SDK will be developed together and with this development, the exchange of any command and/or information with the VR-Cloud® server will become possible. That's not all. You will be able to develop an application more practical than ever before, an example being an application into which the new VR environment and simulation feature as well as online contents are integrated together.

  • When the client PC connects itself to the server, scripts stored in the server will be sent and they can then be executed by the client.
  • The building of user interface as well as various operations including transactions with the VR-Cloud® server can be feasible by the client.
  • One example of an application would be the standard script that makes all commands that are available in the current VR-Cloud® server accessible from the menu.

Examples of application that can be developed using the SDK

  1. A project focusing on road, traffic, and driving simulation
    The development of an UI that allows the display of a user interface in which roads and/or driving scenarios are listed in an intuitive way, which consequently make users' life much easier when using the software themselves.
  2. An interactive PR and guidance to tourist hot spots and events using VR technology.
    An optimal client developed especially for the purpose of attracting visitors to a particular place or event, by combining UC-win/Road's context or script feature.
  3. An interactive map with a navigation feature
    The development of an application that displays an interactive map, which can be installed in public transportation infrastructures such as airports and railway stations and can also be made available on each of their websites.
      -Ability to switch the display quickly between 2D map and 3D environment
      -Introduction/directions to shops and the use of collaborative contents
      -Providing a feature that allows you to attach a tag to 3D models and also search buildings/infrastructures.
       -Thanks to the implementation of the route search engine algorithm, it is now possible to develop a feature that displays the route you should take to get from where you are to where you want to go.
  4. Generation of 3D GIS viewer
    The development of an application that provides a user interface specialized in urban planning through the use of GIS technology.
      -Management of object attributes such as address, size, ID, name, etc.
      -Filtering objects such as buildings and trees and displaying the search results within the 3D environment.
      -Switching the display between the proposed plan and its alternative
      -Offering an analysis feature that calculates density and checks the outline of a building.
  5. Emergency rescue and evacuation training
    Rescue simulation for training rescue squads so that they can act accordingly in the event of an emergency can be built, a plug-in for visualizing fire propagation simulation can be developed, and an interactive hazard map that shows safe evacuation routes and shelters at a time of disaster can be created, all by combing scripts and scenarios coupled with real-time navigation.
