| 8 | |
| 9 | |
| 10 | ---Purpose: Defines an Interactive Object by gathering together |
| 11 | -- several object presentations. This is done through a |
| 12 | -- list of interactive objects. These can also be |
| 13 | -- Connected objects. That way memory-costly |
| 14 | -- calculations of presentation are avoided. |

| 39 | ---Purpose: Initializes the Interactive Object with multiple |

| 42 | -- it is projector dependent. |
