1. 3D animation function
   3D model's animation based on released xml format.
   It is available to create various type of 3D model's animation
   based on the information of model's location.
   It enables to run several data at the same time.


2. Snap function for vehicle and pedestrians
   It is capable to automatically adjust the height and inclination of models on the road and the terrain in UC-win/Road.


3. The control for the existing objects
   It is available to control static objects such as traffic light.


4. The drawing effect control for the objects
   Move command, state of traffic light, transparent, MD3 character animation.


5. UC-win/The optimal integration with the functions of UC-win/Road
   Script can control the playback function. Interaction is supported in drive simulation.

●File Format

The movement and status of all 3D models in a scene are defined in the XML format for saving animation data. 3D meshes of the models are not stored this file, but a link to the associated 3D model is. Additionally, it's possible to set weather, time and other visual effects.

●Model Instance

The "Model Instance" contains "Type" information and is associated with the model's profile. Moreover, the instance contains a list of states defined by time, so that the location, direction, animation and display status can be set for each state. There are two types of "Model Instance" (temporary instance" and "scene instance"). Temporary instances can be generated in real time whilst running a simulation, however, they can't be saved in the UC-win/Road project. The 3D model profile selected at the time of generation is used. When a profile hasn't been assigned, an instance will not be generated. A scene instance can be generated at the same time as a temporary instance, however it will be saved with the project. This instance can be assigned for a model instance that exists in the current UC-win/Road project as a part of the scenery. A traffic light is an example of a "Scene Instance". During simulation, instances generated by UC-win/Road are controlled by XML data.

●Simulation Playback

A playlist can be created to play more than one XML file at the same time. The playlist has a time offset for each item and can be used simultaneously for multiple datasets. Moving objects are created in place and move based on a linear interpolation of location coordinates. During simulation, traffic flow is set to on. In addition, long distance simulations over short time periods and high-speed playback of low-speed movements are also available.

●Time Unit

A number of time units are supported. Notably, support is planned for absolute time including date and time.

●Traffic Simulation

There are two major functions.

Snap placement of instances to existing roads, footpaths and terrain

In some cases, the simulation program doesn't use elevation or a road alignment is different to the one in the VR space in UC-win/Road, so the snap function places the simulation results in the specified position in UC-win/Road. When searching for the optimal road or snap location, the following parameters are considered.

1. Distance from the road and lane
2. Comparison of road structures on the trajectory of the object instance
3. Additional information from the XML file

Control of the instances of moving vehicles with UC-win/Road traffic animation

When reproducing a micro simulation, the traffic in UC-win/Road can be initialized in any state.

●Major GUI Functions

Preview window

This displays a 2D preview of the XML file. In this window, set the area for the scene you want to display, assign scene instances to UC-win/Road objects and so on.

Model profile editor

Create profiles and register 3D models.

Playlist editor

The playlist editor is effective even when multiple simulations are being performed simultaneously. The time span of the simulation is displayed on a Gantt chart. It's possible to drag & drop as well as input time offsets for simulations.

Player

A tool bar to control animation is displayed at the bottom of the screen.

Camera mode

Two new camera modes have been added.

1. A spin mode that follows moving objects
2. View from the centre (or a specified location) of an object

Option screen

Set the parameters for the traffic snap method.
