From the April 2014 Leap Motion V2 hackathon. Pitched by Walter Gray.
- Leap Motion V2 SDK or newer
- SWIG 3.0.0 or newer
- D compiler
- A C++ compiler such as g++ or clang++ that comes with Xcode
On OS X, one can install the SWIG and D prerequisites via MacPorts:
sudo port install swig swig-d dmd
The installation steps for HomeBrew are likely similar, as would
be installing via apt on Linux. Using this under Visual Studio
is possible but likely more involved.
swig -c++ -d -d2 -o LeapD.cpp -wrapperlibrary LeapD Leap.i
clang++ LeapD.cpp libLeap.dylib -shared -o libLeapD.dylib
dmd Leap.d Leap_im.d -run Sample.d
If your Leap Motion device is streaming frames, you should see some valid frame data, e.g.:
frame id = -1
frame id = 90364
frame id = 90367
frame id = 90370
...
In case you have trouble with SWIG or clang, the intermediate
source files and binaries (at least for Xcode) are included
here so you may skip to running dmd on OS X.
