Introduction †

SIGVerse Web is a Web Interface for SIGVerse Application Development. Together with SIGViewer, SIGVerse application development can be done without command-line interface terminal (e.g. Cygwin). A light-weight programming editor with multiple languages support is equipped on the system to ease programming jobs. Code compiling (make), building of project files, and execution can be done with just a click. Furthermore, the web-based system also enable development to be carry out anywhere with just an internet browser. Main feature of SIGVerse Web:

Web-based Editor and Compiler
Remote Control SIGServer
Workspace on the Cloud

Setup †

↑

Register and Login Webuser account †

Pull down the top panel for web registration and login http://web.iir.nii.ac.jp/sigverse/web/login/index.php

↑

SIGVerse Installation/Uninstallation †

On the main page, after Connect to Socio, select the desired version and click to install/uninstall SIGVerse.
*Important* After clicking the Install button, please allow some time (~5 mins) for the processing until a long list of output is displayed. Please do not press any other button during the processing.
Once the installation is completed, you can click Go to access your Workspace.

* Socio Server Access †

In order for SIGViewer to visualize your simulation running on Socio server, you are required to have an access account on the server. Please contact Professor Inamura (inamura@nii.ac.jp) to apply an access account and follow the guide here http://www.sociointelligenesis.org/SIGVerse/index.php?SSH%E6%8E%A5%E7%B6%9A to establish the SSH connection.

Workspace Overview †

Project Directory
- The left panel consists of a file navigation for project directory. You can create new project folder and file, upload project file, and even import a whole project (Refer to Import below).

Editor Area
- The center area is the editor for programming code developments. It supports multiple programming languages with syntax highlight, search and replace, and multi-tab for working of several files in parallel.

Control Panel
- The lower panel is the Control Panel for code compiling and execution.
- Make - To make controller codes with a Makefile. Please make sure to prepare the Makefile.txt as below (sample):

Makefile.txt

Build - To "build" the project files into the current SIGVerse version (indicated on the right end of Control Panel).
Import (.zip) - To import a project from local machine, upload the zip file of the project (with all files inside) onto Project Directory. Press Import to extract it (refresh to view the new folder).
Export - To download a project in zip format.
Delete - To delete a project (with all files inside).
Execute [Admin] - For administrative purpose only.

↑

Running Simulation †

Run - To execute SIGServer (./sigverse.sh).
Check - To view output of the execution (for possible error).
Kill - To terminate SIGServer.

First Test (Tutorial01) †

To simulate a falling object due to gravitational and external forces.
Step 1: Create a new project
- Click the Add Folder icon on the top of the left Project Directory.
- Insert "Tutorial01" and click SAVE.
- A new folder named "Tutorial01" appears on the Project Directory.

Step 2: Create an agent controller
- An agent is an autonomous object controlled by a controller.
- Click into "Tutorial01" and click Add File to create the controller source code.
- Insert "MoveController" and select "cpp" as the file type.
- Insert the following codes into the Editor Area and click SAVE.

MoveController.cpp

The above controller codes do nothing except execute "onAction" on every 5 s.

Step 3: Compiling the controller codes
- Create a file named "Makefile" with "txt" file type.
- Insert the following codes into the Editor Area and click SAVE.

Makefile.txt

Click Make and refresh the Project Directory to ensure the creation of "MoveController.so" file.

Step 4: Create a virtual world with the agent
- Create a new file named "NewWorld" with "xml" file type.
- Insert the following codes into the Editor Area and click SAVE.

NewWorld.xml

The above codes create a virtual world named "myworld".
In the world, an agent named "Toy_D" using the instance of "seToy_D.xml" is created.
The "implementation" attribute attaches "MoveController.so" as the controller of the agent.
With the "dynamics" attribute value set to "true", the agent is subjected to dynamics simulation.
The initial position (x,y,z) and mass are set.

Step 5: Execute the simulation
- On the Control Panel, build the project by using Build.
- Set "Port" to 9001 and "World" to "NewWorld.xml"
- Click Run to execute SIGVerse.
- Click Check to check the last line of the output is " Java VM start ok" for successful execution.
- Run SIGViewer. Establish SSH connection under Setting. Set host name as "localhost" and port no. to "9001". Click Connect to SimServer.
- An agent in a virtual world appears as follows.

#ref(): File not found: "toy_1.jpg" at page "動力学シミュレーションのサンプル"

Click Send under SIM_CTRL_CMD (START) to start the simulation.
The agent falls straight down the ground.
Disconnect SimServer in SIGViewer and Kill in the Control Panel to terminate the simulation.

Step 6: Apply external force
- To apply an external force to the agent, edit the agent controller as follows:
