vtk画折线，并且禁止鼠标交互

VTK画图，禁止鼠标拖动时滚动图形，鼠标滚轮滚动时放大/缩小图形的方法。

renderLine.InteractiveOff();

下面是VTK画折线的代码

// Create five points
            double[,] p = new double[,] {
                { 0.0, 0.0, 0.0 },
                { 1.0, 0.0, 0.0 },
                { 0.0, 1.0, 0.0 },
                { 0.0, 1.0, 2.0 },
                { 0.0, 3.0, 3.0 }
            };

            // Create the points
            vtkPoints points = vtkPoints.New();
            for (int i = 0; i < 5; i++)
                points.InsertNextPoint(p[i, 0], p[i, 1], p[i, 2]);


            vtkPolyLine polyLine = vtkPolyLine.New();
            polyLine.GetPointIds().SetNumberOfIds(5);
            for (int i = 0; i < 5; i++)
                polyLine.GetPointIds().SetId(i, i);

            // Create a cell array to store the lines in and add the lines to it
            vtkCellArray cells = vtkCellArray.New();
            cells.InsertNextCell(polyLine);

            vtkPolyData polyData = vtkPolyData.New();
            polyData.SetPoints(points);
            polyData.SetLines(cells);

            vtkPolyDataMapper mapper = vtkPolyDataMapper.New();
            mapper.SetInput(polyData);
            vtkActor actor = vtkActor.New();
            actor.SetMapper(mapper);
            //vtkRenderWindow renderWindow = renderWindowControl1.RenderWindow;
            //vtkRenderer renderer = renderWindow.GetRenderers().GetFirstRenderer();

            //vtkRenderer renderLine = vtkRenderer.New();
            //renderLine.SetBackground(0.2, 0.3, 0.4);
            renderLine.AddActor(actor);

            renderLine.ResetCamera();
            vtkCamera camera = renderLine.GetActiveCamera();
            camera.Zoom(1.5);


            //渲染窗口添加网格渲染器
            renderWindow.AddRenderer(renderLine);

            //渲染窗口开启双缓冲
            renderWindow.SetDoubleBuffer(1);
            renderWindow.Render();
