如何使用libfreenect2爲OSX上的骨架跟蹤設置OpenNI2和NITE？

Question

我剛剛在OSX 10.11.5上設置了libfreenect2，我可以成功運行顯示RGB /紅外/深度流的Protonect演示，但我還想使用OpenNI/NITE進行骨架跟蹤。

我已經按照在OpenNI回購的README文件中的指令，但是當我試圖運行NiViewer我得到這個：

NiViewer 
openDevice failed: 
    DeviceOpen using default: no devices found 

Press any key to continue . . . 

我目前正在經歷libfreenect2問題在GitHub和記錄了我試着和結果here。任何提示/提示都很有幫助。

什麼是最簡單的方法來設置和測試在OSX上使用Kinect v2的libfreenect2的OpenNI/NITE？

原來我的時候，我應該一直在使用NiTE2.2 我只是從libfreenect2/build/lib到NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers/複製libfreenect2-openni2.0.dylib然後跑了SimpleUserTracker樣本和它的工作使用NITE 1.5！

還有一個問題：打印到控制檯的樣本運行，但打開窗口和渲染的樣本不起作用。沒有窗口被渲染，就像該線程被阻塞了一樣。 那是當我使用集成英特爾GPU。如果我使用離散nVidia GPU應用程序崩潰：

我該如何克服這個問題？

Answer 1

此處僅供參考，以aswer作爲參考。 這就是我使用libfreenect2獲取OpenNI2/NITE2.2骨架跟蹤以及它的OpenNI2驅動程序。我有：

1. 編譯通過自制安裝OpenNI2並用OpenNI2支持按照github repo's readme instructions
2. 下載NITE2.2（替換Nite1.5其中我被前missusing）
3. 複製libfreenect2 OpenNI2驅動器（ibfreenect2 /編譯libfreenect2 build/lib/libfreenect2-openni2.0.dylib）到我需要運行NITE2的Drivers文件夾（例如NiTE-MacOSX-x64-2.2/Samples/Bin/OpenNI2/Drivers）。

我已經想通了的道路是錯誤的通過設置日誌級別的OpenNI.ini爲verbose：

[Log] 
; 0 - Verbose; 1 - Info; 2 - Warning; 3 - Error. Default - None 
Verbosity=0 
LogToConsole=1 
LogToFile=1 

[Device] 
;Override="" 

[Drivers] 
; Location of the drivers specified by a relative path based on OpenNI's shared library or an absolute path. 
; Path separator "/" can be used to be portable for any platforms. 
; Default - OpenNI2/Drivers 
Repository=OpenNI2/Drivers 

西蒙Kaliski遵循的筆記和寫使用OpenFrameworks輝煌Kinect 2 on OSX with skeleton tracking後，一定要一探究竟！

而且，一旦libfreenect2被編譯與openni2支持它甚至可以在處理中被使用，簡單地丟棄libfreenect2-openni2.0.dylib在/Documents/Processing3/libraries/SimpleOpenNI/library/osx/OpenNI2（在OSX）：
