| Cluster Function（price on application） (1)Overview The cluster system has been developed for use with large-scale and complex driving simulators. This new system synchronizes the work of two or more PC’s and outputs the resultant image to multiple monitors, thus making it possible to maintain a constantly high level of performance and frame-rate irrespective of the number of channels since each channel is displayed on an independent PC. It is still possible to output from one PC to two or more monitors without using this cluster option, however you will find the performance of the system decreases as the number of channels increases. (2)Structure The cluster system is composed of a master machine and multiple client machines. Master Machine The 3D driving simulation is developed and calculated within the user’s master machine. Client Machine The client machines receive the information required for displaying the VR space from the master machine. Channel Synchronization This system transmits the data from the master machine to the client using multicast on UDP. The number of clients does not depend on the communication performance of the master machine, as by using the multicast software many client machines may be connected, even with standard network hardware. Synchronization is performed only over an Ethernet network at this time, but in future even better performance will be achieved by use of the Quadro G-Sync system being developed by NVIDIA. Failsafe Processing This is a mechanism that ensures that the simulation and synchronization will continue even if an unexpected breakdown occurs in one of the client machines. Moreover, if a client machine fails to respond, the synchronization is automatically restarted. (3)Channel Composition This system enables the projection of the VR Space onto a large screen, or an entire sphere, by dividing the image projection between client machines so that each client outputs a certain part of the total image for example the left/right/top image. Two different settings for the Projection method are available:
(4)User Interface The client machines can be easily set up by setting only the master connection information and the client name. The entire simulation operation is controlled from the master machine via an improved user interface. The following functions are available. At set up：
(5) License Price The Cluster System is composed of two components, the master and the client. The master machine requires an additional (separately-priced) cluster option as well as the standard license. Each client machine then requires a ‘viewer licence’ under which the VR data cannot be edited. One client license is required for each channel. (6)Future Development
Off Road Function Users can drive vehicles around the 3D VR space using a steering wheel, a game controller or the keyboard in UC -win/Road. Previously driving was only possible on a road carriageway; users were not able to drive through the environment if there was no road in the 3D space. This limitation was removed in UC-win/Road V7. It is now possible to drive off-road and also to start driving anywhere within the environment by setting up a driving start point wherever you wish on the terrain.
However, the road friction and sound properties must be manually assigned to the terrain when driving off-road. These can be assigned to various terrain textures in the "Edit road surface" window. Other UC-win/Road Drive Simulator features, such as force feedback and scenarios are also available for off-road driving.
3DS Output Function This function enables all models within the UC-win/Road 3D space to be output in an arbitrary 3D model data format. This enables users to output data from UC-win/Road in 3DS format for input into such standard CAD tools as 3dStudio Max. In addition to allowing output in 3DS format, the following output formats will be made available in future: FBX, OBJ, VRML and OpenFlight .
xpswmm plug-in The script and scenario functions were added to the xpswmm plug-in. As a result, it is now possible to reproduce a chain of events, such as the height of the water surface, displaying the contours as well as the reflection of a tsunami for example… The reproduction speed and the repetition or the simulation can be controlled via the playback function. The display of the analysis results can be controlled according to the simulation and presentation. The analysis data of xpswmm can be utilized more easily and is more interactive than before. Sidra plug-in It came to be able to do the import of the design data of latest version (Sidra Intersection 5.1) of intersection design software Sidra by revision of the Sidra plug-in. As a result, importing the shape, the section, the traffic signal control, and the traffic quantity etc. of the intersection designed by latest Sidra will be possible. |
