MAC OS X上的编译：
https://www.vtk.org/Wiki/VTK/Building/MacOSX
编译vtk使得QT版本为5
cmake configure:
cmake ./ -G "Unix Makefiles" \
-DVTK_USE_QVTK:BOOL=ON \
-DCMAKE_INSTALL_PREFIX=/usr/local \
-DVTK_USE_GUISUPPORT:BOOL=ON \
-DVTK_QT_VERSION=5 \
-DModule_vtkGUISupportQt:BOOL=ON \
-DModule_vtkGUISupportQtOpenGL:BOOL=ON \
-DModule_vtkGUISupportQtSQL:BOOL=ON \
-DModule_vtkGUISupportQtWebkit:BOOL=OFF \
-DModule_vtkRenderingQt:BOOL=ON \
-DModule_vtkViewsQt:BOOL=ON
then make and make install
vtk在mac上的编译安装就完成了。

Unix平台编译，查看CMakeCache.txt中的值是有效的。链接路径为LD_LIBRARY_PATH。
The basic setup of source -> mapper -> actor -> renderer -> renderwindow is typical of most VTK programs.

搜索cpp 的类：
vtkRegularPolygonSource类对应的URL是：
https://www.vtk.org/doc/nightly/html/classvtkRegularPolygonSource.html
如果要搜索其他的类介绍，可以直接将classvtkRegularPolygonSource换成class + 类名 即可。

写、读STL文件
#include <vtkPolyData.h>
#include <vtkSTLWriter.h>
#include <vtkSTLReader.h>
#include <vtkConeSource.h>
#include <vtkSmartPointer.h>
#include <vtkPolyDataMapper.h>
#include <vtkActor.h>
#include <vtkRenderWindow.h>
#include <vtkRenderer.h>
#include <vtkRenderWindowInteractor.h>
#include <vtkProperty.h>
void generateSTL( std::string filename )
{
vtkSmartPointer<vtkConeSource> coneSource =
vtkSmartPointer<vtkConeSource>::New();
coneSource->Update();
vtkSmartPointer<vtkSTLWriter> stlWriter =
vtkSmartPointer<vtkSTLWriter>::New();
stlWriter->SetFileName(filename.c_str());
stlWriter->SetInputConnection(coneSource->GetOutputPort());
stlWriter->Write();
}
void readSTL( std::string inputFilename )
{
vtkSmartPointer<vtkSTLReader> reader =
vtkSmartPointer<vtkSTLReader>::New();
reader->SetFileName( inputFilename.c_str() );
reader->Update();
vtkSmartPointer<vtkPolyDataMapper> mapper =
vtkSmartPointer<vtkPolyDataMapper>::New();
mapper->SetInputConnection( reader->GetOutputPort() );
vtkSmartPointer<vtkActor> actor =
vtkSmartPointer<vtkActor>::New();
actor->GetProperty()->SetColor( 0, 1, 0 );
actor->SetMapper( mapper );
vtkSmartPointer<vtkRenderer> renderer =
vtkSmartPointer<vtkRenderer>::New();
vtkSmartPointer<vtkRenderWindow> renderWindow =
vtkSmartPointer<vtkRenderWindow>::New();
renderWindow->AddRenderer( renderer );
vtkSmartPointer<vtkRenderWindowInteractor> renderWindowInteractor =
vtkSmartPointer<vtkRenderWindowInteractor>::New();
renderWindowInteractor->SetRenderWindow( renderWindow );
actor->SetPosition( 0 , 0, 0 );
renderer->AddActor(actor);
renderer->SetBackground( 0, 0, 0 ); // Background color green
renderWindow->Render();
renderWindowInteractor->Start();
}
int main(int argc, char *argv[])
{
if(argc != 2)
{
std::cout << "Required parameters: filename.stl" << std::endl;
return EXIT_FAILURE;
}
generateSTL( argv[1] );
readSTL( argv[1] );
return EXIT_SUCCESS;
}
相关CMakeLists.txt为：
cmake_minimum_required(VERSION 2.8)
PROJECT(vtkLearn)
find_package(VTK REQUIRED)
include(${VTK_USE_FILE})
add_executable(${PROJECT_NAME} main.cpp )
target_link_libraries(${PROJECT_NAME} ${VTK_LIBRARIES})
编译运行：
cmake ./
make
./vtkLearn cone.stl
得到：
关于vtkObject中的PrintSelf:
PrintSelf的接口是这样的：
void PrintSelf(ostream& os, vtkIndent indent) override; 想要打印到标准输出中，我们可以这样：
ostream out( std::cout.rdbuf() );
renWin->PrintSelf( out, *vtkIndent::New() );
// renWin是指向vtkRenderWindow对象的指针
