问题描述
我想做一个能从串口里面读取传感器传入的现实单摆的角度，然后能在WPF上模拟的3D动画，目前已经做出了3D模型和简单动画，但是没法动态修改AxisAngleRotation3D里的Angle值，它只能简单地从From到To……求高人帮忙改改。程序如下~假定我在C#里，传入的角度值是nowangle，目的就是想，让AxisAngleRotation3D的Angle值一直和nowangle保持一致，该怎么写呢？C#代码：publicpartialclassMainWindow:Window{publicdoublenowangle;publicStoryboardsb1=newStoryboard();publicDoubleAnimationda1=newDoubleAnimation();publicMainWindow(){this.InitializeComponent();getanimation();sb1.Begin();}privatevoidgetanimation(){#regionda1.SetValue(Storyboard.TargetNameProperty,"rotation");da1.SetValue(Storyboard.TargetPropertyProperty,newPropertyPath(AxisAngleRotation3D.AngleProperty));da1.From=rotation.Angle;da1.To+=nowangle;//da1.Duration=TimeSpan.FromSeconds(0.5);//da1.AutoReverse=true;//da1.RepeatBehavior=RepeatBehavior.Forever;sb1.Children.Add(da1);this.Resources.Add("Storyboard",sb1);#endregion}}
