作了较全面的封装 将各 种三维模型的存储 运算 显示 交互等内容全都以类的方式封装起来了 并且提供比 OpenGL 强大得多的功能 可惜 VTK 最大的缺点是 没有免费的教程 它只提供免费的 API 手册 其中只是对各个类的功能罗列而已 而参考书籍则需要花几十美元去购买 所以学 习 VTK 只 能依靠它的大量 Example 了 由于我的项目需要兼故未来跨平台的可能 目前只在 Windows 下 所以必须使用一套跨 平台的开发库 在 VTK Examples GUI 的例子里 Windows 平台下只有 SDK MFC C Builder 这几个例子 另外还有 Motif Python Tcl 选择是不少 但是 Motif 听说编程 比较麻烦 我也从来没有接触过 Tcl 和 Python 作为脚本语言 其性能和安全性则有些令 人担忧 也就是说 这里面没有一个是我能使用的 说起跨平台 由于单位里项目的 关系 我接触得比较 多的就是 QT 了 所以 在未选定 VTK 之前 其实我是打算使用 QT OpenGL 的组合方式来开发这个软件的 其实 如果不考虑跨平台 我还是会选择 QT 因为它的事件处理方式对于用惯 Delphi 的我而言 更为顺手 那么现在使用了 VTK 是否 还能将 VTK 和 QT 组合起来使用呢 作为试验 我仿照 VTK Examples GUI Win32 SampleMFC 制作了以下这个小程序 很顺利 结果证明了我的猜想 QT 和 VTK 是可以很方便的结合起来的 下面就跟我来一步步制作这 个程序吧 1 从 http www vtk org 下 载 VTK 的最新版本 我用的是 4 2 该包中只有程序文件 你还需要自己编译 为此你还需要 CMake 用来生成 VC 的 dsw dsp 文件 然后用 VC 打开 生成的工程文件 并进行编译 最后将编译后生成的目录 VTK bin Debug 加入到 Windows 系统环境的 Path 中 2 下载 QT 我目前使用的是 QT334 打开 VC 的 Tools Options Directories 将 QT 的 bin include lib 路径分别加入其中 3 在 VC 中 建立一个新的 Win32 Console Application 工程 建立一个 main cpp 作为 main 函数的入口 代码如下 include include testwindow h int main int argc char argv QApplication app argc argv TestWindow testwin testwin show app connect 精品文档 2欢迎下载 return app exec 其中的 testwindow h 是程序的主窗口 TestWindow 的头文件 一会将会建立该文件 这段程序所做的是 初始化 QApplication 并将 TestWindow 显示出来 并进入主程序的消 息循环 app exec 下面实现 TestWindow 类 分别建立 testwindow h 和 testwindow cpp testwindow h include class TestWindow public QMainWindow Q OBJECT public TestWindow TestWindow testwindow cpp include testwindow h include moc testwindow h TestWindow TestWindow TestWindow TestWindow 你 是否注意到了 testwindow cpp 中的 include moc testwindow h 一行 这个 moc testwindow h 将会建立 TestWindow 的 RTTI 信息 并且绑定消息等 它并不 需要我们 自己实现 而是由 qt 的一个名为 moc 的程序建立 在 VC 的 FileView 中 右键点击 testwindow h 并选择 Settings 然 后在打开的 Project Settings 对话框中选择 Custom Build 页 在 Commands 中填入 moc i testwindow h o moc testwindow h 意思是调用 moc 程序 根据 testwindow h 的内容 自动生成一个名为 moc testwindow h 的 moc 文件 在 Outputs 中填入 moc testwindow h 精品文档 3欢迎下载 然后 在 Project Settings 中选中 projct 在 Link 页的 Object library modules 中加入 qt mt334 lib 精品文档 4欢迎下载 编译程序 如果顺利 一个简单的 QT 程序就写好了 它会在启动后显示一个空白的窗口 3 加入 VTK 的代码 这些代码都可以参考 Examples GUI Win32 SampleMFC 程序 将 testwindow h 改造成如下 include include

TutorialTutorial forfor usingusing QtQt withwith VTKVTK Hi I am a newbie in VTK and Qt For some time now I have been trying to use VTK with Qt but faced a lot of problems getting started and configuring them In the end it worked thanks to Anja Ende Clinton Stimpson and everyone who helped me get started I am writing down the procedure to get VTK to work with Qt in visual studio 2005 environment Hopefully this document will help other newbies save a lot of time I have tested the following procedure with MS Visual Studio 2005 Professional on Windows XP Pro X64 1 Install and get Qt working as per the instructions here This works fine and you can start using Qt with visual studio for those who just want to use Qt with Visual Studio this is how we do it 2 Install and configure VTK using Cmake with a VTK USE GUISUPPORT option and b VTK USE QVTK option set to ON If Qt is installed after VTK you will need to reconfigure VTK to find Qt 3 Now it s time to test the configuration with a code which uses both Qt and VTK You can try it with the example in VTK source Examples GUI Qt Imageviewer Copy this code only the cxx file to a new directory 4 I use qmake to generate build files The method to build this example using qmake is a open visual studio command prompt go to the directory containing the cxx file and type qmake project this makes a pro file Open this file in an editor and modify it as below Automatically generated by qmake 2 00a Wed Oct 11 17 14 01 2006 TEMPLATE vcapp this was originally app modify it to vcapp TARGET DEPENDPATH INCLUDEPATH here include the path to all the directories containing the 精品文档 10欢迎下载 header files LIBS add this line and include all the libraries Qt and VTK needed for the application Input SOURCES main cxx b Save the pro file and run qmake from the command prompt again This will generate a vcproj file Open this file in visual studio and build it there If you included all the libraries and include paths this should build and run perfectly I used qmake for building because I didn t know how to do it with Cmake But if the experts here can throw light on that it would help many Also if someone knows of any other way probably easier and smarter to use Qt with VTK please add to this document Thanks Ashish Go to the top of the page Quote Skip user information alexiuk Beginner Posts 2 2 Thursday May 10th 2007 6 04pm 精品文档

working fine when compiled with CMAKE now l try to compile the same examples with Qtcreator and his qmake funtion doesn t work I updated my pro with the includepath and library but doesn t work do you

QTQT VTKVTK inin LinuxLinux Hi just wanted to share my experience on a jump start with using Qt VTK As I don t have experience with using Qt I decided to go the easiest possible way downloaded Qt4 and the QtCreator The steps I took next 1 Built Qt4 from source and installed it 2 Added usr local Trolltech to my PATH environment variable 3 Downloaded the source for VTK 5 4 4 Launched ccmake in the root of the source tree 5 Switched ON VTK USE GUISUPPORT VTK USE QVTK 6 Pressed c to configure in ccmake and specified the version of Qt 4 0 7 After configuring in ccmake launched cmake and then make and make install 8 The needed QVTKWidget h will be in the usr bin local include vtk 5 4 9 Now we launch QtCreator and create the simple application 10 In the mainwindow h I add these headers
