The earthwork volume calculation function has been added to the UC-win/Road Ver.13. This function allows users to calculate approximate volume of the earthwork by using the 3D shape of roads and terrains created in the software (Fig.1).

The use of 3D data in the civil engineering industry is becoming far more popular. This new calculation function uses the 3D shape of the earthworks for calculation instead of the common average section method.

After the intersection of road and terrain is calculated, roads are divided into two areas. One is the field where the road surface is higher than the terrain (banking), and another is the area where it is lower than the terrain (cutting). The volume between both surfaces is calculated by using the divided 3D surface shape data.

For calculating road surfaces, users now can select cross sections for civil engineering instead of the existing road cross section setting. The construction foundation and the embankment and cutting can be defined as with the current road cross section definition. Since default civil engineering cross section is automatically generated from existing road section, the volume of earthwork can be calculated after the normal data creation without any additional inputs (Fig.2).

The amount of soil can be calculated by entering the road, earthwork cross section, distance from beginning to end, and pitch of the road surface. Users can define these items one by one, but also can use a batch creation function when calculating earthworking volume by a constant range or each cross section. Calculation by section enables the calculation of the cost including the amount of soil volume in each block. It can also be used for comparative review of different cross sections by using multiple earthwork cross sections.

Zone function
We have newly developed a zone function that allows users to define areas and to conduct various operations and calculations for the field. Borders of zones can be continuously created on the 3D screen with just a few clicks. In UC-win/Road Ver.13, acquisition of the area of zone and the max / min elevation, creation of forest and block model are available. In the future, this function will be integrated with other functions such as object selection and group creation, field usage setting, land creation function and the designation of map data import range.

Cluster system can transmit and receive camera data
The cluster system can now transmit camera data created from the master to client side. This enables the setting of eye direction with a far higher degree of freedom by linking the camera sensor simulation on a client side to the camera sensor base plug-in on the master system. Thus it is now possible to simulate multiple cameras.

Customization for each scenario
In general, scenarios are created for each simulation when conducting several simulations in one virtual space. In previous versions of the software, it was necessary to switch the customization processing of plug-ins, developed with the system development kit (SDK), depending upon the individual experiment. However, in Ver 13 users can now call certain plug-ins from the scenarios they have created, and this makes the processing of the customized plug-in management much easier. This means that because one decides which plug-ins to use for each experiment when designing the scenarios, operators never make the mistake of selecting the wrong plug-in. This function can also be used when conducting the same experiments multiple times.

2. Setting the distance of mist / fog (for Mist: Linear)
   To accurately control the viewing range within the simulation the start position of the fog and the distance of any whiteout from the camera position can be selected in meters.
3. Enhancement of sound system
   The sound of rain heightens the realism of the simulation. Different sound qualities are used for walking and driving. The sound quality and volume changes according to the amount of rain. The purpose of this function is to reproduce the potential drop in the driver's attention caused by excessive noise, in addition to rising a sense of immersion. The sounds can be output from other audio devices connected to the special speaker by means of the scenario setting.

1. Model display at the position of controller
   A 3D model you set is shown on the display and it moves according to the motion of the controller. It is useful to see the scale of motion in VR space since a model can be displayed at the position of sensor too.
2. Function to move the point of view
   The reference point of view can be moved with the controller buttons. The VIVE provides a playing space of 5m in the diagonal, and moving the reference viewpoint lets users move around a wider VR environment.
3. Scenario / Script menu
   In the case of the previous version, users had to take off the HMD temporarily and operate the software to play scenarios and scripts. In this version, users can display the menu and execute them from a controller.
