KinectV2 in Qt 在Qt中使用KinectV2编程-小明编程

配置了下，原来在Qt中是可以使用KinectV2编程的，我之前一直以为必须中visual studio囧~

Github代码

这次放出最简单的KinectV2数据在Qt中显示的例子。有个地方很怪，kinect数据本来是按照b、g、r、a排列，可以用这个Qt QImage方法显示（qt教程中说The image is stored using a 32-bit RGB format (0xffRRGGBB).这个32bit的数字，在windows x86下内存恰好按照从低到高排序，也就是0xBB 0xGG 0xRR 0xff，因此恰恰对应上了）。由于Kinect中的a数据默认是0，所以一般请不要使用，不然就全透明无法显示了。。
