The project file controls the outlook and the behavior of the model. The file structure is as follows:

• 1st line: the magic number. Must be S2HB (case sensitive). This serves only identification purposes, as the software, which evaluates it first reads these 4 characters and if it is not S2HB, then it rejects to read the rest.
• 2nd line: Version section: [VERSION]
• 3rd line: Version number. Current version number is 1.
• 4th line: Colors section: [COLORS]

5th line up to the volumes section: Color definition of the different volume sets.

• 1st column: Volume set name
• 2nd column: Red color component (integer 0..255)
• 3rd column: Green color component (integer 0..255)
• 4th column: Blue color component (integer 0..255)

Volumes section: [VOLUMES]

Following lines till the end: Volume definitions. Each line defines a volume.

• 1st column: Volume number. Begins with 1, in each line increases by 1. This is redundant information for the software, but might be useful for the user, if he/she wants to modify the file in a text editor. It helps to quickly find any entry.
• 2nd column: X component of the displacement vector (in the model length unit)
• 3rd column: Y component of the displacement vector (in the model length unit)
• 4th column: Z component of the displacement vector (in the model length unit)
• 5th column: File name (currently STL, OBJ and OFF formats are supported), without folder path.
• 6th column: Volume set name. Must match with one of the entries in the colors section. Different volumes can belong to the same volume name set. The different volumes in the same set can be shown, or suppressed in the same time. It makes your presentation manageable and organized.
• 7th column: Volume description. Can take multiple lines. Line break is marked by <br>. This column is optional.

The project file is a necessary item. It takes probably the most time to prepare (apart from the model of course). It is recommended to do the preparation in a spreadsheet software (e.g.: Excel, LibreOffice Calc) and when it is completed, just copy+paste it into a text file. Therefore the columns will be separated by TABULATOR instead of SPACE. The file must have .dat extension and this file must be the only one with such extension. If you upload multiple .dat files, then one of them will be randomly chosen as the project file.
