If an operation has to deal with arrays of different lengths, the shorter array gets repeated to fill up the larger. vvvv includes a feature it calls ''boygrouping'', where one computer controls a number of slave computers to operate in parallel, with all programming and editing done on the master computer.

. vvvv currently supports DirectX 9 (including PS 3 and VS 3 shader techniques) and DirectX 11. In April 1st 2020, vvvv gamma, a new version of the software, reprogrammed from scratch, was publicly released. vvvv was initially developed by the Frankfurt-based media collective MESO as an in-house tool for their own projects, but was then released. vvvv is now maintained by th
