VTK编译出现no override found for 'vtkPolyDataMapper'
我出现no override found for 'vtkPolyDataMapper'，这种问题是因为没有用cmake，而是直接用控制台结合VTK的库函数进行开发的。
参考博文 https://blog.csdn.net/thecentry/article/details/79111295
demo运行结果：
一个vtkRender可添加多个actor，同时显示，结合上面代码：
1 vtkSmartPointer<vtkCylinderSource>cylinder1 = vtkSmartPointer<vtkCylinderSource>
::New();
2 cylinder1->SetHeight(
6.0);
3 cylinder1->SetRadius(
1.0);
4 cylinder1->SetResolution(
10);

7 vtkSmartPointer<vtkPolyDataMapper> cylinderMapper1 = vtkSmartPointer<vtkPolyDataMapper>
::New();
8 cylinderMapper1->SetInputConnection(cylinder1->
GetOutputPort());
9
10 vtkSmartPointer<vtkActor> cylinderActor1 = vtkSmartPointer<vtkActor>
::New();
11 cylinderActor1->
SetMapper(cylinderMapper1);
12 //
13 vtkSmartPointer<vtkRenderer> cylinderRender = vtkSmartPointer<vtkRenderer>
::New();
14 cylinderRender->
AddActor(cylinderActor);
15 cylinderRender->
AddActor(cylinderActor1);
16 cylinderRender->SetBackground(
0.1,
0.2,
0.4);
类的介绍
（1）vtkCylinderSource
该类派生自vtkPolyDataAlgorithm。该类生成的数据类型是vtkPolyData，生成一个中心在渲染场景原点的柱体。
（2）vtkPolyDataMapper
该类用于渲染多边形几何数据（vtkPolyData），派生自类vtkMapper，将输入的数据转换为集合图元（点/线/多边形）进行渲染。
vtkPolyDataMapper::SetInputConnection(): VTK可视化管线的输入数据接口。
（3）vtkActor
该类派生自vtkProp类，渲染场景中的数据的可视化表达通过vtkProp的自类负责。
（4）vtkRenderWindow
(5)vtkRender
(6)vtkRenderWindowInteractor
(7) vtkInteractorStyleTrackballCamera
