SIMulateur TAbleur DYNamique

Compilation (Linux or OS X): You'll need MySQL, GTK+2 and Legacy OpenGL and sorry the original Makefile has been lost ! Call one of the script shell depending on your OS:

cd src/
./build-ubuntu.sh

or:

cd src/
./build-osx.sh

Note concerning OSX:

• if an error message "ld: library not found for -lssl clang: error: linker command failed with exit code 1 (use -v to see invocation)" try to type in your console: xcode-select --install
• OpenGL is now badly supported with GTK+ (while working well in 2004): the current bug is the OpenGL background color covering all GTK+ widgets :(

This is the version made in 2004 by students having just learnt C. So this is not a finished application.

In a frist Linux console, start MySQL:

/etc/init.d/mysql start

Since that make >15 years I did not practice MySQL and lost root password I do the following hack and working on root mode. Please do not follow this bad practice ! Live safe !

/etc/init.d/mysql stop
sudo mysqld_safe --skip-grant-tables

In a second Linux console, start SimTaDyn:

./SimTaDyn

• Drag to the left the vertical pan to show the Forth menu.
• Connect to MySQL server:
  • Click from menu Carte/Fichier > Connexion to MySQL
  • On the popup window, configure:
    • Host: localhost
    • User: root (for example)
    • Password: admin (for example)
    • If this is the first time: Gestion des carte: Nouvelle: mymap or if one has already been created Gestion des carte: Database: mymap. Click on the corresponding Validate button.

If this step is not done, SimTaDyn will crash when trying to add a cell !

• Click on the red button Passer en mode SOMMET and click on the plus button Ajouter une cellule.
• Click two times at 2 different position on the black window on the left. You have added two nodes.
• Click on the green button Passer en mode ARC and click on the plus button Ajouter une cellule.
• Click at on each node. You have added an arc.
• Continue the operation to create a triangle shape.
• Click on the house button Passer en mode ZONE and click on the plus button Ajouter une cellule.
• Click at on each arc. Click again on the first arc. You have added an area.
• To save it, type >TABLE on the Forth intrepeter in the right side, near the notebook tab Nouveau.

In the frist Linux console, type:

mysql -u root

Inside MySQL, type:

use mymap;
show tables;
SELECT * FROM arc;

• On the Forth intrepeter in the right side, near the notebook tab Nouveau, you can type

1 2 +

• Press Ctl-Enterkey or press the Executer button. You will see *** OK ***.
• Click on the floating window Montreur de champs and click on Pile, you will in the stack the number 3.
• On the Forth intrepeter again, execute . you will notice the number 3 has disapeared in the stack and a message 3 *** OK *** appeared.

• Now on the tab Carte in the floating window Montreur de champs unroll list and click on the different fields, you will see the map shows the selected information (cost, name, id, forth words ...).
• Click on the green button Passer en mode ARC and click on the plus button Selectionner une cellule.
• Now, select Arcs > Cout.
• With the mouse select a region of the map to select several arcs.
• Type on the entry box on the top position of the map and type a number ie 42. Type enter. The selected arcs have now the cost 42.
• Now, select Sommets > Forth, select and type a forth word, see the selected arcs have the new forth word on them.
• Note that selected cells are pushed on the stack Pile. When deselecting cells they are poped off. You can execute Forth command on selected cells.

• Click on the button Executer N times the map. A basic example could be each node computes the mean of costs of its neighbor.

• Rhe Forth interpreter have some words manipulating the map. For example
  • 1 2 A+ allows to add a new arc from nodes 1 and 2 (Note a bug the window has to be refreshed to see the operation).
  • 1 DEG . show the degree of the node 1.

The 2d mode is the most evolved but you cannot move the map, the 3d mode has not really be made and the camera control (mouse and keyboard) is a total disaster :)
