我正在尝试更改图像窗口的宽度和级别。

我知道我需要创建 vtkWindowLevelLookupTable。并将其附加到映射器。就像这里描述的那样。

我不明白这个映射器来自哪里以及它的输入连接是什么。我的代码：

 _reader2 = vtkDICOMImageReader.New();
            _reader2.SetDirectoryName(path);
            _reader2.Update();

            // Visualize
            _ImageViewer2 = vtkImageViewer2.New();
            _ImageViewer2.SetInputConnection(_reader2.GetOutputPort());


            var image = _ImageViewer2.GetInput();

            // get range of slices (min is the first index, max is the last index)

            _ImageViewer2.GetSliceRange(ref _MinSlice2, ref _MaxSlice2);

            this.vScrollBar2.Maximum = _MaxSlice2 + 1 + vScrollBar2.LargeChange - 1;
            Debug.WriteLine("slices range from : " + _MinSlice2.ToString() + " to " + _MaxSlice2.ToString());

            vtkRenderWindow renderWindow = renderWindowControl2.RenderWindow;

            _interactorStyle2 = vtkInteractorStyleImage.New();
            _interactorStyle2.MouseWheelForwardEvt += new vtkObject.vtkObjectEventHandler(interactor_MouseWheelForwardEvt2);
            _interactorStyle2.MouseWheelBackwardEvt += new vtkObject.vtkObjectEventHandler(interactor_MouseWheelBackwardEvt2);

            renderWindow.GetInteractor().LeftButtonPressEvt += new …

我candidate function(s) not accessible在调用某些成员时遇到编译错误,尽管我将它们声明为public.当涉及来自vtk的某个类(作为返回类型或参数)并且要调用的类与调用代码不在同一个VS项目中时,我只得到错误.我也试过其他vtk类型没有运气:(

这是一些测试代码:

// A.h, in a seperate class library
#include <vtkActor.h>
public ref class A
{
public:
    A(void);

    void test1(vtkActor* actor);
    vtkActor* test2();
    void test3(char* actor);
    char* test4();
};


// B.h, Same as A but in the same project as the calling code 
#include <vtkActor.h>
ref class B
{
public:
    B(void);

    void test1(vtkActor* actor);
    vtkActor* test2();
    void test3(char* actor);
    char* test4();
};

我试着从同一个项目中调用函数B是这样的:

// calls to class library
A^ …

For example, if i have a cube

(this part of code is from the vtk python example)

import vtk

# create a rendering window and renderer
ren = vtk.vtkRenderer()
renWin = vtk.vtkRenderWindow()
renWin.AddRenderer(ren)

# create a renderwindowinteractor
iren = vtk.vtkRenderWindowInteractor()
iren.SetRenderWindow(renWin)

# create cube
cube = vtk.vtkCubeSource()

# mapper
cubeMapper = vtk.vtkPolyDataMapper()
cubeMapper.SetInput(cube.GetOutput())

# actor
cubeActor = vtk.vtkActor()
cubeActor.SetMapper(cubeMapper)

# assign actor to the renderer
ren.AddActor(cubeActor)

# enable user interface interactor
iren.Initialize()
renWin.Render()
iren.Start()

How can i delete this cube …

给定一个 vtk 图像：

vtkSmartPointer<vtkImageData> VTKImage = vtkSmartPointer<vtkImageData>::New();

这是一个包含分割结果为二进制数据的 3D 图像（分割对象 = 1，背景 = 0），如何提取分割对象的表面并将其保存为 VTKpolyData？
