HOWTO use pot2surf through V_Sim to create a .surf file. Originnally written by Luc Billard for his program VISUALIZE, pot2surf allows you to create .surf files from .pot files. Please refer to V_Sim's website to learn about .pot files specifications. To use pot2surf through V_Sim, you need to select the "pot2surf" tab under the "convert" button of the "isosurfaces" module. You must then select a .pot file from which to build a .surf file and a name for the .surf file to build (notice that if you first select a .pot file, the other field will be auto filled by V_Sim but you can always specify the file names you want by yourself). Once you've selected your .pot file, pot_min and pot_max fields are automatically filled by V_Sim. These are the min and max values V_Sim found in your .pot file. Of course you can't create surfaces which isovalues aren't in the ]pot_min, pot_max[ range. You can now add surfaces to build by using the "+" button on the right column. Surfaces' names are auto-filled but you can change them by selecting and clicking them. Surfaces' name can't contain space character, but can contain any other you want. They should always by with the 'surface_' prefix. You can also specify the value of a surface by selecting and clicking the value field of a surface. You can remove any surface by clicking the "-" button, or re-orders them all by using the up and down arrows. The order is important if you want to use the "Play" function of the "isosurface" tab. Once you've added several surfaces to the list, you can click the "Build target .surf file" button to have your .surf file created. If no error message appears, it means the surf file you specified have been created succesfully. If you have selected "Autoload", your .surf file should be displayed in V_Sim (don't forget to check the "Use isosurfaces" button in the main panel !). Buttons in the toolbar are used to save/restore settings by exporting/reading it as a .instruc file.
