以下是使用Helix Toolkit、WPF和C#建立三维坐标系,添加坐标网格,并绘制三维折线图的示例代码:
```csharp
using HelixToolkit.Wpf;
using System.Windows;
using System.Windows.Media;
using System.Windows.Media.Media3D;
namespace WpfApp1
{
public partial class MainWindow : Window
{
public MainWindow()
{
InitializeComponent();
// 创建一个Viewport3D对象
var viewport = new Viewport3D();
// 创建一个ModelVisual3D对象,用于存放3D模型
var modelVisual = new ModelVisual3D();
// 创建一个坐标系
var coordinateSystem = new CoordinateSystemVisual3D()
{
ShowXAxis = true,
ShowYAxis = true,
ShowZAxis = true,
ArrowLengths = new Vector3D(0.2, 0.2, 0.2),
FontSize = 0.1,
FontWeight = FontWeights.Bold,
Labels = new List<string>() { "X", "Y", "Z" },
LabelColors = new List<Color>() { Colors.Red, Colors.Green, Colors.Blue }
};
// 创建一个坐标网格
var grid = new GridLinesVisual3D()
{
Width = 10,
Length = 10,
Thickness = 0.01,
MajorDistance = 1,
MinorDistance = 0.5,
Center = new Point3D(0, 0, 0),
Normal = new Vector3D(0, 0, 1),
UpDirection = new Vector3D(0, -1, 0),
MajorGridLineBrush = Brushes.LightGray,
MinorGridLineBrush = Brushes.Gray
};
// 创建一个三维折线图
var helix = new HelixToolkit.Wpf.HelixViewport3D();
var lineBuilder = new LineBuilder();
for (double t = 0; t < 20 * Math.PI; t += 0.1)
{
double x = Math.Cos(t);
double y = Math.Sin(t);
double z = t / (20 * Math.PI);
lineBuilder.AddLine(new Point3D(x, y, z), new Point3D(x + 0.1, y + 0.1, z + 0.1));
}
var linesGeometry = lineBuilder.ToLineGeometry3D();
var linesModel = new GeometryModel3D()
{
Geometry = linesGeometry,
Material = Materials.Red,
BackMaterial = Materials.Red
};
helix.Children.Add(new ModelVisual3D() { Content = linesModel });
// 将坐标系、坐标网格和三维折线图添加到ModelVisual3D对象中
modelVisual.Children.Add(coordinateSystem);
modelVisual.Children.Add(grid);
modelVisual.Children.Add(helix);
// 将ModelVisual3D对象添加到Viewport3D对象中
viewport.Children.Add(modelVisual);
// 将Viewport3D对象添加到窗口中
this.Content = viewport;
}
}
}
```
