LeapRS is a safe wrapper for LeapC, the Leap Motion C API. It uses the generated binding provided by leap-sys.
This is an API for accessing Leap Motion/Ultraleap hand tracking device. It only works on Windows.
**Warning**: This library is not complete and not fully tested. Moreover, it includes unsafe code to interact with the C API. It should be treated with caution in its current state. It has not yet been used in any actual application.
The goal of LeapRS is to cover entirely LeapC in a safe way. It is intended to be as close as possible to the original C library. As such, it's fairly low level and carries most of the difficulties of using LeapC.
It is not intended to provide any full featured framework such as having a worker thread and provide an async API. It is intended to be usable to create such framework though.
The current coverage is partial. It includes everything needed to capture hand position in a single device setup. It misses multi-device management and most of the image manipulation methods. It also misses interpolation methods.
To build and run programs, you first need to install the LeapMotion Tracking Software.
This library was created for the version named Geminy (5.6.1).
If you install this software in a custom path, you need to define the
environment variable LEAPSDK_LIB_PATH (default: C:\Program
Files\Ultraleap\LeapSDK\lib\x64)
