在C#/XAML中通过滑块旋转模型的问题

Question

晚安，

我目前正在尝试使用缩放范围为0-360'的滑块围绕给定轴旋转"关节1"。我已经绑定了滑块来获取值，并将其放入函数"Move_Joint1"中，该函数应该根据用户输入的滑块对对象应用旋转。然而，当把函数放在我的主窗口中时，但函数似乎没有执行。我曾尝试使用console.writeline来尝试输出该值，但没有输出任何值。没有错误或警告。

如有任何帮助，我们将不胜感激。

下面是XAML和C#代码片段。

更新-

检查值已更改的事件，然后在创建的事件处理程序中发布代码以旋转模型似乎已经奏效。然而，0-360似乎让我的模型旋转了不止一圈

private void slJoint1_ValueChanged(object sender, RoutedPropertyChangedEventArgs<double> e)
{
Matrix3D transformationMatrix7 = Shoulder1.Transform.Value; //Gets the matrix indicating the current transformation value
transformationMatrix7.Rotate(new Quaternion(new Vector3D(0, 0, 1), slJoint1.Value)); ; //Makes a rotation transformation over this matrix
Shoulder1.Transform = new MatrixTransform3D(transformationMatrix7);
}

Answer 1

使用事件，我将角度从GUI传递到代码后面，然后使用下面的代码更新模型的旋转角度。

public void Move_Joint1(double angle1,double angle2)
{
Transform3DGroup Joint1Group = new Transform3DGroup();

Joint1Group.Children.Add(new TranslateTransform3D(new Vector3D(0, 0, 185)));
Joint1Group.Children.Add(new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(0, 0, 1), angle1)));
Shoulder1.Transform = Joint1Group;
Move_Joint2(angle1,angle2);
}

public void Move_Joint2(double angle1,double angle2)
{
Transform3DGroup Joint2Group = new Transform3DGroup();
Joint2Group.Children.Add(new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(0, 0, 1), -90)));
Joint2Group.Children.Add(new TranslateTransform3D(new Vector3D(150, 0, 253)));
RotateTransform3D Joint2Rotation1 = new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(0, 0, 1), angle1));
Joint2Rotation1.CenterX = Joint2Group.Transform(new Point3D(0, -150, 0)).X;
Joint2Rotation1.CenterY = Joint2Group.Transform(new Point3D(0, -150, 0)).Y;
Joint2Rotation1.CenterZ = Joint2Group.Transform(new Point3D(0, -150, 0)).Z;
Joint2Group.Children.Add(Joint2Rotation1);
Point3D origin = Joint2Group.Transform(new Point3D(0, 0, -70));
RotateTransform3D Joint2Rotation = new RotateTransform3D(new AxisAngleRotation3D(new Vector3D(0.1, 0, 0), angle2));
Joint2Rotation.CenterX = origin.X;
Joint2Rotation.CenterY = origin.Y;
Joint2Rotation.CenterZ = origin.Z;
Joint2Group.Children.Add(Joint2Rotation);
Arm1.Transform = Joint2Group;
}
