UC-win/Road SDK requires Embarcadero® Delphi to develop the plug-in because the API of UC-win/Road SDK is made by Delphi. UC-win/Road plug-in, as a runtime library of Embacadero® Delphi, is either loaded during the start-up of UC-win/Road or by using UC-win/Road plug-in manager on the screen. It enables customization of UC-win/Road by accessing from plug-in to applications or the existing data.

* Delphi Professional or higher edition is required, and only RDelphi 10.2 Update1 is supported. It will support the soon.

●C++ API

Users can develop UC-win/Road plugins in C++ language. This API is more organized and easier to understand than previous UC-win/Road SDK, and can be accessed as a C++ object.

●Python Interface (COM API)

Python API accesses the main features of UC-win/Road via COM. You can access features such as driving simulator control, real-time model/character control, main screen viewpoint control, and ribbon menu item and button control.

Library Folder

Stores the various library files necessary to compile the plug-ins.

Plugins Folder

Stores source codes of various sample programs. By compiling and carrying out, it will be helpful for the understanding of functions controllable by SDK.

Help File

Describes the API interface and how to set Delphi. Only in English for the current version.

SDK has a variety of functions such as creating and editing UC-win/Road data, data exchange, data processing, addition of UI (User Interface), and driving simulation control. The followings are the main functions:

■Reference and change of static data constructing VR space

1. Terrain
   Converting polygon coordinates, elevation of designated plane coordinates, mesh size, and coordinate system
2. Road linear
   IP point coordinate on horizontal alignment and vertical alignment, road length, slope, relaxation curve and arc settings, information of each lane
3. Road section
   Cross section, sort of lane and curb, cutting/banking/tunnel section shape, texture reference
4. Intersection
   Shape, texture, marking, traveling path, traffic light (Signal phase, Traffic control)
5. Model
   Polygon structuring models, texture, basic color, parts configuration, size, action setting, rotate, scale, origin position
6. Placement model
   Building, 2D tree, 3D tree, vehicle, background, sign, side objects, video wall, 3D text, new creation

▲Terrain

▲Placement models

▲Road linear

■Model/Character real time control

1. Control of character coordinate
   Characters walk according to the real-time control of coordinates, orientation, inclination, etc. It can be used to visualize other analysis program.
2. Control of movable parts
   A part of model can be moved by calling movable setting specified to the 3D model.

▲Control of character coordinate

▲Control of movable parts

■Control of drive simulation

■Log function

■Viewpoint control of the main screen

■Free drawing of OpenGL Control

■User operation acquisition

■Customization of GUI (Graphical User Interface)

1. Addition of input/information display dialog
   Creating and controlling parameter input window and information window.
2. Addition/management of control
   You can add menu items and tool bars in the main menu, and change the action at the time of selecting existing tools.

▲Addition of input/information display dialog

▲Addition/management of control

You can load and compile sample projects, create a plugin and run it to see how it works and understand the source code process to implement the functions.
For example, a program carrying out various settings of the traffic flow is available. "Traffic Generator Set" will be added in the tool menu. When you click, it adds the "arbitrary traffic volume point" in the center of each road and the basic settings can be made. The setting of the traffic flow generating point of the edge of the road can also be done.

▲Quad information of the road
(Acquisition of the shape of the road)

▲Display and selection of the sound
receiving point (object instance)

1. Driving simulation
   In driving simulation, obtaining the physical quantity of the vehicle in real time becomes possible by using the log function.
   It can be used in a variety of analysis by obtaining information of the vehicle driven by the user and vehicles of the surrounding. For example, by freely incorporating the driving characteristics, safety, and judging algorithm of eco driving, it can be used in education and research. The information output are as follows.
   
   
   1. Location and direction of the vehicle
   2. Location information in regard to road and roadway
   3. Driving operation quantity of the user
   4. Vehicle's speed, acceleration, engine RPM, and gear
   5. Vehicle attributes: Weight, size, gear ratio, engine torque, break stress, and friction coefficient
   
   
2. Customization of vehicle driving model
   Customization of the driving characteristics of the vehicle to drive becomes possible. It replaces the standard driving model of UC-win/Road, and it can program the vehicle driving algorithm in regard to the user's driving operation.
   Using the VR environment of UC-win/Road, driving simulation can be done by customized driving model.
   
   
3. Model Real Time Control
   Moving and showing/hiding the 3D model registered in the data in VR space becomes possible. If you give only the location information in UC-win/Road, an animation of the character model will be played according to the actual movement speed. A representation of a free movement is possible besides the movement along the flight route or road which is the basic function of UC-win/Road. By developing linkage with external data, a VR representation of the micro simulation becomes possible.
   
   
4. Cloud Programming World Cup
   From 2013, FORUM have held the contest every year that students compete programming skills by using System Development Kit (SDK).
