VR-Studio(R) is an advanced VR system made with the latest architecture. New features include large-scale project support which can handle multiple terrain data, new CAD style user interface utilizing diagrams and objects, multi-user editing, improved performance based on multi threading and modified section functions.
Large scale data
SinceVR-Studio does not have a limit on the scale of data, you can create large scale data of over 100km. It allows you to design long-driving roads and create wide areas and traffic networks. If you would like to enhance the area, you can add terrain area, it allows you to reuse the data you have created and enables efficient work. We have developed functions of terrain creation and terrain processing. VR-Studio(R) has 50m mesh DEM data. (use of survey data is approved by Geographical Survey Institute)
VR-Studio can process in parallel by adapting multi core CPU and multi CPU. At the time of dividing triangles and generating LOD data, VR-Studio does parallel processing. at the time of triangle division of terrain data and generation of LOD data.
Terrain LOD function
Since VR-Studio has adapted LOD (Level of Detail) technology, it can display terrains of wide area speedily. Surface of the terrain is basically expressed by the triangle. If you draw detailed terrain in VR space at the point distant from the view, triangle of a few pixels or triangle of smaller than one pixel might be drawn. Since the triangle has being drawn at the same place, the process will be useless. With LOD, VR-Studio draws a visible triangle on screen in a certain size, and estimates the size of the triangle to reduce the amount of processing and draws a triangle combined from multiple triangles based on the size of triangles.
This technology enables better display performance even when handling a large scale terrain because the number of triangles does not increase. In addition, for a reduction in the processing time and updating the screen each time. Data is saved of the combined triangle in advance, and selects and displays the appropriate combined data while processing drawing.
Terrain Procedural Texturing
This technology processes images to paste on 3D objects. VR-Studio selects image from height and slope and alters the image to fit to the shape. It enables realistic terrain expression from DEM data or TIN data
Creating VR space
VR-Studio allows you to create VR space that consists mainly of outer building space and makes terrain and roads easily. In addition, it allows creating lakes, flight routes, background, rivers and pipes and the setting of 3D models and trees.
By setting the horizontal alignment, longitudinal slope, cross slope by an element of cross section the 3D model of a road is generated automatically. You can easily set, move, add and delete transition points with mouse clicking, you can also enter the exact figures for the actual road design representation. After you have created road alignment, you can define the cross slope by cross section. Creation of the road alignment is finished by making the necessary cross section first and applying it to road alignment.
Elements placed on the road, such as a cross-section, bridges and tunnels are set according to the distance from the starting point. You can add a station point and set the elements based on the distance from the station point. Station point should be set based on the distance from the other elements (including the start point). If you change the position of the station point, the element belonging to the station point is updated. With this feature, after setting station points in along the road, you can easily correct the positioning of the elements after editing and road alignments.
Cross section and cross section parts
One cross section comprises of combinations of multiple parts. The parts define the width of the parts of a road. For example, vehicle road, pedestrian road curve and division can be made as a part.
While you can change the gradient for the width of the road by using a cross-section, you can change the gradient for the width of part of the road at any point. It is possible to update only the width in that position. If you set a modifier element, you can set the following.
VR-Studio has function to create whole traffic network. It allows you to make road structure below easily and efficiently.
Bridges and tunnels are automatically generated by defining cross section of road bridge beam or tunnel wall and setting bridge and traffic space on road alignment. To lengthen the traffic network, you can connect independent to the end of the road.
VR-Studio allows the editing of one project by multi users with multi-user editing function. Users can share the data with the source management server, and manage store and synchronize. When you work, get the latest status of the data from the management server, and you can update the data on the server after editing by the local machine. When multiple users work simultaneously, the element is locked to edit and one element can be edited by only one user. After editing is over and server data is updated, the lock will be released and other users can edit the data. Work by this procedure allows simultaneous editing of the independent elements by multiple users. It leads to improved efficiency in working with large-scale data.
In addition, complete editing history is recorded by using the management server, it allows you to return to incorrect data on the previous status and edit.
This function allows comparing of multiple plans at the time of presentation and assessment or comparing before and after the construction of the project for improvement. All of the models, or part of the models can be switched to another condition-reality. It allows examining multiple marking plans of intersections, comparing road alignments and comparing house developments and other plans
VR-Studio has sample data. The shape of the terrain data is not rectangular. The length of the highway-like road is 70 km. If you move to the favorite point "Mt. Fuji", you can see the sight from the top of the Mt. Fuji. Move to camera position "Projectview", you can see the interchange. If you look at ramps at the interchange, you will find that the road is divided or connected with the large angle and you can see the smooth connection of roads at the junctions and sections.
Move to camera position "Townup", here is a 3-junction intersection to the sliproad to the highway. VR-Studio allows the changing of road structures including intersections. When you drive the road, you can drive a car in any direction or alongside the road as well as in any of the existing lanes within the sample data.
