VL Convex Hull

Hey guys, first of all, happy new year!

I’m a relatively new user of vvvv, and I’m following Takuma Nakata’s tutorials to get to know the software a little bit better. I’m now trying to replicate this patch(,

I’m having some issues in replicating this effect, due to the fact that the image pack is now outdated and some of the essential nodes for this work are no longer present.
I know that OpenCV is integrated with VL in vvvv and most of the image pack functions should be present there, but I’m having some troubles in figuring out what to do, especially with grouping and scattering points on the perimeter.

Does anyone have any tips, advice, or help patches that could make me achieve the intended effect?

Thanks :)
