SIGVerse Web
SIGVerse Web とは？ †
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
セットアップ †
Webuser アカウントの登録 †
SIGVerse のインストール/アンインストール †
- メインページで， Connect to Socio の下に，必要のバージョンを選択し，SIGVerse をインストール/アンインストールする。
- *重要* Install ボタンをクリックした後，出力の長いリストが表示されるまで，処理のためにいくつかの時間を（〜5分）できるようにしてください。処理中に他のボタンを押さないでください。
- インストールが完了すると，Go ボタンをクリックして， Workspace にアクセスする。
* Socio サーバーのアクセス †
- 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 a permanent access account OR you can use the following method for temporary access (monthly renewal).
- Download the SSH-Key (On the main page after login to SIGVerse Web) and extract the files (id_rsa and id_rsa.pub) into (SIGViewer installed directory)\SIGViewer-<version>\SIGViewer\.ssh folder (* Default directory is C:\Program Files\).
- Please find the passphrase in the passphrase.txt.
- For security reason, the key and the passphrase will expired at the end of every month. Please renew the key at the beginning of every month.
- Follow the guide below (SSH Connection) to establish the SSH connection using SIGViewer.

- Passphrase: (as written in passphrase.txt)
#ref(): File not found: "ssh_connect2.jpg" at page "SSH接続"
- Check the Use RSA key to login.
- Enable port forwarding (in most cases blocked by firewall) by the following steps.
- Check Local port forwarding with login and input the following details:
- Local port: Port on local machine
- Listen host: Listening machine（normally localhost)
- Remote port: Port on server
#ref(): File not found: "ssh_connect3.jpg" at page "SSH接続"
- Check Remote port forwarding with login and input the following details:
- Server port: Port on local machine
- Listen host: Listening machine（normally localhost)
- Local port: Port on server
#ref(): File not found: "ssh_connect4jpg.jpg" at page "SSH接続"
- * In normal cases, please use 9001 and above for local port forwarding, and 8001 and above for remote port forwarding. If the port number is currently in used, please try other number.
- Check Download shape file for automatically update shape files from server.
- Press Connect, the SSH connection is established if the message "SSH Authentication succeeded (server host name)" appears on the bottom left of SIGViewer.

チュートリアル †
最初のテスト (Tutorial01) †
- To simulate a falling object due to gravitational and external forces.
- ① 新しいプロジェクトの作成
- 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.
- ② エージェントコントローラの作成
- 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.
- ③ コントローラー·コードのコンパイル
- Create a file named "Makefile" with "txt" file type.
- Insert the following codes into the Editor Area and click SAVE.
Makefile.txt
- In the Control Panel, insert the project name "Tutorial01" for work/ and click Make. Refresh the Project Directory to ensure the creation of "MoveController.so" file. If "MoveController.so" file is not created, means there is a compilation error during Make. Check your programming codes. Also, in the Makefile.txt, ensure that there is no any extra space in front and behind the lines, and the spacing in front of the last line (...g++) is a tab and not multiple space bar.
- ④ エージェントと仮想世界の作成
- 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.
- ⑤ シミュレーションの実行
- 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.
- If you see "cannot bind socket: Address already in use", just try another port number other than 9001.
Try bigger number, e.g. 9002, 9003, 9004, ... There are various reasons why the port is temporary being used.
- 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.
- * View controls for SIGViewer:
- Turn around - Right click
- Zoom - Ctrl + Right click
- Pan - Shift + Right click
#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.
- ⑥ 外力の加える
- To apply an external force to the agent, edit the agent controller as follows:
MoveController.cpp
↓
- Make, Build and Run the simulation as above.
- The agent moves forward as below.

SIGVerse Web と一般的な開発の違い †
SIGVerse Web is developed with the aim to ease and reduce learning curve for novice users (who are not familiar to Linux environment) to begin with SIGVerse development. The development process explained above is slightly different to manual programming developments illustrated in the rest of the tutorials in this wiki.
- The files system in SIGVerse Web is organized based on "Project". You can develop all related files (.cpp, .so, .xml, .wrl, .x3d, etc.) under the same project folder. By using "Build", SIGVerse Web will automatically build all the files into the respective folders of the current SIGVerse version that you are working on. This files system will provide a better files organization and enables "Import" and "Export" of projects for backup and sharing purposes.
- *違い* In World files (.xml), the path to the controller's shared object file (.so) is always at the current directory, example:
- In SIGVerse Web, you can install and execute all available versions of SIGVerse servers in the same development environment. Because of the independent files system, the same project codes can be executed in different SIGVerse versions based on your selection when you enter the workspace.
- *違い* To make sure the Makefile indicates the current SIGVerse version in your workspace during compilation, please make sure the first line of the Makefile.txt is as follows:

- World Gallery
- Living Room (Small)
- Living Room (Big)
- Kitchen
