在C#中使用VTK(Visualization Toolkit)来绘制坐标轴和网格线可以通过以下步骤实现:
1. 导入VTK库:
```csharp
using Kitware.VTK;
```
2. 创建vtkRenderer和vtkRenderWindow对象:
```csharp
vtkRenderer renderer = vtkRenderer.New();
vtkRenderWindow renderWindow = vtkRenderWindow.New();
renderWindow.AddRenderer(renderer);
```
3. 创建vtkRenderWindowInteractor对象并设置renderWindow:
```csharp
vtkRenderWindowInteractor renderWindowInteractor = vtkRenderWindowInteractor.New();
renderWindowInteractor.SetRenderWindow(renderWindow);
```
4. 创建vtkAxesActor对象来绘制坐标轴:
```csharp
vtkAxesActor axesActor = vtkAxesActor.New();
axesActor.AxisLabelsOff(); // 关闭坐标轴标签
axesActor.SetTotalLength(1, 1, 1); // 设置坐标轴长度
axesActor.SetShaftTypeToCylinder(); // 设置坐标轴形状为圆柱体
axesActor.SetCylinderRadius(0.02); // 设置坐标轴圆柱体半径
axesActor.SetConeRadius(0.1); // 设置坐标轴锥形半径
vtkOrientationMarkerWidget axesWidget = vtkOrientationMarkerWidget.New();
axesWidget.SetOutlineColor(0.9300, 0.5700, 0.1300); // 设置边框颜色
axesWidget.SetOrientationMarker(axesActor);
axesWidget.SetInteractor(renderWindowInteractor);
axesWidget.EnabledOn();
```
5. 创建vtkCellArray和vtkPolyData对象来绘制网格线:
```csharp
vtkCellArray cellArray = vtkCellArray.New();
vtkPolyData polyData = vtkPolyData.New();
polyData.SetPoints(points); // 设置网格点坐标
for (int i = 0; i < numberOfLines; i++)
{
vtkLine line = vtkLine.New();
line.GetPointIds().SetId(0, lineIndices[i, 0]);
line.GetPointIds().SetId(1, lineIndices[i, 1]);
cellArray.InsertNextCell(line);
}
polyData.SetLines(cellArray);
```
6. 创建vtkPolyDataMapper和vtkActor对象来渲染网格线:
```csharp
vtkPolyDataMapper mapper = vtkPolyDataMapper.New();
mapper.SetInputData(polyData);
vtkActor actor = vtkActor.New();
actor.SetMapper(mapper);
actor.GetProperty().SetColor(1, 1, 1); // 设置网格线颜色
renderer.AddViewProp(actor);
```
7. 最后,启动渲染循环:
```csharp
renderWindow.Render();
renderWindowInteractor.Start();
```
以上是简单的示例代码,你可以根据你的需求进行修改和扩展。希望对你有所帮助!
