Here we’re having a look at individual nodes that work differently in VL in regards to vvvv:
In vvvv an IOBox (String) connected to a pin that takes a filename or directory, automatically adapts to it so that you can right-click on it and get an open-dialog to choose a file or directory accordingly.
In VL there is an IOBox (Path) to handle file and directory paths but it doesn’t know (yet) which you’d want to choose. So by default a rightclick is opening a FileDialog. To get a DirectoryDialog you have to press Shift while rightclicking!
Map and MapRange
But beware of two differences:
There is one difference to take care of: The multiplication order is inverted. VL uses the textbook convention of the quaternion multiplication whereas vvvv is using the DirectX implementation which deviates from the official convention so that quaternions behave in the same way as rotation matrices. But most 3D engines nowadays use the textbook convention and we comply in order to make it easier to read foreign documentation/code that also uses quaternions.
