在场景中创建实时更新“图形”

Question

我目前正在使用带有Kinect的visual python来跟踪一个人右手的移动数据。通过我现在的程序，一个人的身体被跟踪屏幕上显示的骨架。我希望根据一个人在该区域更频繁地移动手的情况来绘制实时更新和增长的球体。基本上这些球体将代表运动密度。我没有运气让球体更新。任何/所有帮助将不胜感激，谢谢！

以下是我对球体的代码。我没有包含骨架代码，因为它正常工作。我是VPython /编码的业余爱好者，所以它可能不是最有效或最有组织的代码

<ion-view hide-back-button="true" view-title="{{vm.title}}">
