在轮询模型中什么不能获得骨架？ [英] what can't obtain skeleton in polling model ?
本文介绍了在轮询模型中什么不能获得骨架？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
大家好。
using WPF and polling-model。
我有一个问题 获得
hipcenter of skeleton。
我想在我的代码中读取HipCenter1的位置值，但我无法获取数据 。
数据有trackID，但没有骨架信息 trackID 。
我不知道该怎么办。
任何建议都很好。

解决方案
由于有超过3个不同的区域，因此很难理解您的代码你正试图抓住骨架信息。我不确定你是否知道，但WPF不适用于这种类型的轮询，应该避免。您可能想要研究
这样做的问题。
至于获取联合信息，您应该只有一个 CopySkeletonDataTo （ 此 。 <跨度> skeletonData <跨度>）;
这将确保您使用一份数据。这应该只对每1/30秒有效，所以保持它。至于获取骨架联合信息，请遵循样本和文档提供的模式。

您需要确保正确跟踪要跟踪的正文并且信息有效。
Hi, guys.
using WPF and polling-model.
I have a problem which to obtain hipcenter of skeleton.
I want to read position values of HipCenter1 in my code, but i can't get the data.
The data have trackID, but have not the skeleton information of trackID.
I don't know how to do.
Any suggestions are good.

解决方案
It is very difficult to understand your code as there are over 3 different areas where you are trying to grab skeleton information. I am not sure if you are aware, but WPF is not designed for this type of polling and should be avoided. You may want to research the issues with doing that.
As for getting joint information, you should only have one CopySkeletonDataTo(this.skeletonData); This will ensure you are working with one copy of the data. This should only be valid for every 1/30 of a second so keep it around. As for getting skeleton joint information follow the pattern provided by the samples and docs.
http://msdn.microsoft.com/en-us/library/jj131025.aspx#Active_User_Tracking
You need to ensure you are correctly tracking the body you wish to track and the information is valid.
