What is not supported or updated? libpd is actively developed and seems to have parity with pd-vanilla 0.51 which most certainly includes [expr] objects already.
You shouln't need to download a dll to make this work. Have you tried by simply using an [expr] object in your patch running on libpd?
This year I've been trying to pick up the project to get it to python3 (and package at pypi.org), some new generators (for vst2/lv2 audio plugins), updated documentation, and some bugfixes submitted by the community.
Currently I've added Distrho Plugin Format (DPF) and Daisy generators, and am looking for better OWL integration (although that will need some transition period on patch compatibility, since they use a separate parameter messaging at the moment).
Check it out here: https://github.com/Wasted-Audio/hvcc
Hopefully we can improve pd-vanilla compatibility and behaviour (we really want [expr] objects that could help a ton with optimizations).
Ok, on the mailing-list this external was mentioned:
I figured out how to build it using flext:
It automatically connects to the leap software and I can get it to spit out data.
Now I'm slowly trying to understand how it works and how the data can be used efficiently. A help-file like mentioned of the 'aka.leapmotion' would be great to have eventually. Maybe with some standard send-objects that can be hooked in to later.
If anyone can try this and play with it maybe we can make a nice help-file with some examples
they claim that a linux sdk will be made available soon.
It's out now and quite stable. They do regular updates and the basic demos are quite usable (can use the Leap in Google Earth now for instance).
there is a max external:
if everyone is happy with the general display, it should be easy to port it to pd
Neat. Would be great to have in Pd!
