环境：win7_64 + VS2012 + VTK6.0 + CMake2.8

说明：实例使用CMake搭建工程

准备：新建目录E:\vtk_Exercise，在该目录下新建3个文件，分别是CMakeLists.txt，RenderCylinder.h，RenderCylinder.cpp

代码引用：https://blog.csdn.net/www_doling_net/article/details/8536376

步骤

step1：编写CMakeLists.txt，其内容如下

CMAKE_MINIMUM_REQUIRED(VERSION 2.8.11)
MARK_AS_ADVANCED(CMAKE_BACKWARDS_COMPATIBILITY)
SET(CMAKE_ALLOW_LOOSE_LOOP_CONSTRUCTS TRUE)
SET(VTK_DIR E:/Thirdparty/x64/VTK)

project(RenderCylinder)

INCLUDE_DIRECTORIES(
    ${VTK_DIR}/include/vtk-6.0
)
LINK_DIRECTORIES(
    ${VTK_DIR}/lib/${ConfigurationName}
)
add_executable(${PROJECT_NAME} RenderCylinder.cpp RenderCylinder.h)

target_link_libraries(${PROJECT_NAME}
	vtkFiltersGeometry-6.0
	vtkIOGeometry-6.0
	vtkIOCore-6.0
	vtkCommonCore-6.0
	vtkInteractionStyle-6.0
	vtkRenderingOpenGL-6.0
	vtkCommonDataModel-6.0
	vtkfilterscore-6.0
	vtkRenderingCore-6.0
	vtkCommonExecutionModel-6.0
	vtkFiltersSources-6.0
)

step2：编写RenderCylinder.h

#ifndef _RENDERCYLINDER_H_
#define _RENDERCYLINDER_H_

//这两行代码必须有，否则编译成功，但运行时报错“no override found for。。。”
//适用VTK6.0及之前的版本,关于这点解释，参见https://www.cnblogs.com/cqu-qxl/p/6234763.html
#define vtkRenderingCore_AUTOINIT 2(vtkInteractionStyle,vtkRenderingOpenGL)
#define vtkRenderingVolume_AUTOINIT 1(vtkRenderingVolumeOpenGL)

#include "vtkSmartPointer.h"

#include "vtkRenderWindow.h"

#include "vtkRenderer.h"

#include "vtkRenderWindowInteractor.h"

#include "vtkInteractorStyleTrackballCamera.h"

#include "vtkCylinderSource.h"

#include "vtkPolyDataMapper.h"

#include "vtkActor.h"

#endif

step3：编写RenderCylinder.cpp

#include "RenderCylinder.h"

int main()
{
    vtkSmartPointer<vtkCylinderSource> cylinder = vtkSmartPointer<vtkCylinderSource>::New();

    cylinder->SetHeight( 3.0 );
    cylinder->SetRadius( 1.0 );
    cylinder->SetResolution( 10 );

    vtkSmartPointer<vtkPolyDataMapper> cylinderMapper = vtkSmartPointer<vtkPolyDataMapper>::New();

    cylinderMapper->SetInputConnection(cylinder->GetOutputPort()); 

    vtkSmartPointer<vtkActor> cylinderActor = vtkSmartPointer<vtkActor>::New();

    cylinderActor->SetMapper( cylinderMapper );


    vtkSmartPointer<vtkRenderer> renderer = vtkSmartPointer<vtkRenderer>::New();

    renderer->AddActor( cylinderActor );

    renderer->SetBackground( 0.1, 0.2, 0.4 );

    vtkSmartPointer<vtkRenderWindow> renWin = vtkSmartPointer<vtkRenderWindow>::New();
    renWin->AddRenderer( renderer );
    renWin->SetSize( 300, 300 );

    vtkSmartPointer<vtkRenderWindowInteractor> iren = vtkSmartPointer<vtkRenderWindowInteractor>::New();

    iren->SetRenderWindow(renWin);

    vtkSmartPointer<vtkInteractorStyleTrackballCamera> style = vtkSmartPointer<vtkInteractorStyleTrackballCamera>::New();

    iren->SetInteractorStyle(style);

    iren->Initialize();

    iren->Start();

    return 0;

}

step4：打开cmake-gui.exe，在where is the source code栏填入路径E:\vtk_Exercise，在where to build the binaries栏填入E:\vtk_Exercise\bin（新建bin文件夹，存放*.sln，CMAKE临时文件等），单击左下角Configure，选择Visual Studio 11 Win64，单击Finish

step5：单击Generate

step6：构建工程结束。查看目录E:\vtk_Exercise\bin下，发现很多文件，打开RenderCylinder.sln，将工程RenderCylinder设为Set as Start Project，按下快捷键F7，开始Build工程，等待结束即可。

step7：我build的Debug版，所以再目录E:\vtk_Exercise\bin\Debug，生成RenderCylinder.exe。双击打开即可。实例运行。
