C# bindings for Leap SDK 4.0.0



It seems leap dropped their own C# bindings completely and we need to build them on our own. I’ve started with this already using CppSharp - but nothing committed yet, will do as soon as I’ve more to show.


a quick test with these looks promising:

building those into a .dll only required to outcomment a few debug-calls. dropping the .dll into vl, connecting 4 nodes, returns what we need…

Leap (Devices) VL

so Orion has all things gestures, tools and pointables removed. other than that it is pretty much the same as before.

initial working version here:


  • get images to work
  • de/serialization
  • cleanup


Hi guys,

I,m pretty insterested to try the orion version, do i have to put some files somewhere vl says no device found althouhg it is connected properly.

does the vl have any example with hand skeleton ?



did you build the sources?


Hi joreg, yes it seems compiled correctly.

do i have to put the VL.Devices.LeapOrion folder in an specific place ?


yes, needs to be in \packs, like so:


but beware: while it basically works, it also needs a proper cleanup still. coordinate system is not vvvv-style and some nodes may still output non-normalized values.


hi joreg,

ok thanks , seems to outputs some values now.

I,ll wait for the proper cleanup ;D but great staff so far.
