VTK是一个基于面向对象的开源三维绘图软件包，安装过程并不复杂，简单的cmake就可以编译安装，具体过程还是要记录一下，以便翻看。
一、安装
1.下载VTK6，可以上官网自行下载：http://www.vtk.org/download/
2.解压到当前目录
3.进入目录创建build文件夹，存放编译文件。
4.进入build文件夹进行配置，进行配置ccmake .. (注意ccmake与..之间有空格，".."代表上一级目录)
5.运行步骤4的代码会跳出一下配置：
如果没有编译过的会提示没有缓存，可以按c进行配置，之后就会出现这个界面，用上下建选择条目，BUILD_SHARE_LIBS 选择ON ，VTK_Group_Qt选择 On就可以了，其它的可以不做更改，再次按c进行配置确认，按g保存配置。
6.执行make
7.最后安装 sudo make install
这样就安装完成了。
二、测试
新建Plane.cxx,写入代码：
#include <vtkVersion.h>
#include <vtkPlaneSource.h>
#include <vtkPolyData.h>
#include <vtkSmartPointer.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>
int main(int, char *[])
{
// Create a plane
vtkSmartPointer<vtkPlaneSource> planeSource =
vtkSmartPointer<vtkPlaneSource>::New();
planeSource->SetCenter(1.0, 0.0, 0.0);
planeSource->SetNormal(1.0, 0.0, 1.0);
planeSource->Update();
vtkPolyData* plane = planeSource->GetOutput();
// Create a mapper and actor
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
#if VTK_MAJOR_VERSION <= 5
mapper->SetInput(plane);
#else
mapper->SetInputData(plane);
#endif
vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
actor->SetMapper(mapper);
// Create a renderer, render window and interactor
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer(renderer);
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow(renderWindow);
// Add the actors to the scene
renderer->AddActor(actor);
renderer->SetBackground(.1,.2,.3); // Background color dark blue
// Render and interact
renderWindow->Render();
renderWindowInteractor->Start();
return EXIT_SUCCESS;
}
新建CMakeLists.txt，写入代码：
cmake_minimum_required(VERSION 2.8)
PROJECT(Plane)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
add_executable(Plane MACOSX_BUNDLE Plane)
if(VTK_LIBRARIES)
target_link_libraries(Plane ${VTK_LIBRARIES})
else()
target_link_libraries(Plane vtkHybrid vtkWidgets)
endif()
之后运行：
cmake ..
make
./Plane
运行效果如下：
如果想要将VTK6的界面在Qt中显示，可以将目录build/lib/libQVTKWidgetPlugin.so文件放置到/usr/lib/x86_64-linux-gnu/qt4/plugins/designer中，记得使用最高权限。
如过是VTK5的版本，libQVTKWidgetPlugin.so文件在build/bin/文件夹下。
问题：
CMake Warning at CMakeLists.txt:5 (FIND_PACKAGE):
By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project
has asked CMake to find a package configuration file provided by
"Qt5Widgets", but CMake did not find one.
Could not find a package configuration file provided by "Qt5Widgets" with
any of the following names:
Qt5WidgetsConfig.cmake
qt5widgets-config.cmake
Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set
"Qt5Widgets_DIR" to a directory containing one of the above files. If
"Qt5Widgets" provides a separate development package or SDK, be sure it has
been installed.
新建CMAKE_PREFIX_PATH到qtbase就可以了。
