手邊還有一台快生鏽的leap motion,閑來無事搗鼓下，先來寫幾篇入門的教程，之後會寫點簡單好玩的demo~~~
準備工作：
LeapmotionSDK下載下傳：
https://developer.leapmotion.com/get-started?id=v3-developer-beta&platform=windows&version=3.1.3.41910
解壓之後輕按兩下EXE安裝SDK
安裝完SDK之後打開App Home，注冊登入之後就可以試下最簡單的ｄｅｍｏ感受下效果，如果提示leap motion未連接配接，可以拔掉重試或者點開桌面右下角leap motion的圖示檢查故障，如果能正常運作程式那麼說明我們的硬體部分沒有問題。
下面可以打開Leap_Motion_SDK_Win_3.1.3\LeapSDK\samples目錄下的sln檔案測試C++能否正常運作，本文用的VS2015，提示版本不相容的時候直接升版本就好，如果用的VS2010或者VS2012選擇對應版本的Sln即可。
下面介紹如何建立一個Leap motion項目配置環境并成功運作示例程式。
類似于opencv的配置環境，我們需要做三件事兒：
1. 把dll添加進環境變量（如果不想添加進環境變量可以把dll拷貝進調試目錄）
路徑為：C:\Users\zmdsj\Desktop\Leap_Motion_SDK_Win_3.1.3\LeapSDK\lib\x86
2. 添加附加依賴項
項目-屬性-連接配接器-輸入-附加依賴項添加Leap.lib
3. 添加包含目錄和庫目錄
包含目錄C:\Users\zmdsj\Desktop\Leap_Motion_SDK_Win_3.1.3\LeapSDK\include
庫目錄：C:\Users\zmdsj\Desktop\Leap_Motion_SDK_Win_3.1.3\LeapSDK\lib
下面建立一個cpp檔案将以下代碼複制粘貼上即可（就是sample.cpp）
