MFC VS2010 Open CASCADE新建自己的工程

最近磕磕绊绊的去尝试用open cascade建立自己需要的工程文件，终于成功了，一直从网上获取方法，今天自己写一点心得，分享给大家。

一、准备：

1、安装 open cascade ，我安装后目录是： C:\OpenCASCADE7.1.0-vc10-64\opencascade-7.1.0 （注意这个是64bit的库），如果是其它目录，请在后续操作，做出对应调整。后面会用到的是lib、inc、src，安装方法很简单，下载官网的安装包，直接安装就好，安装好后目录内容如下：

2、IDE使用的是：VS2010

二、建立MFC工程

建立工程可以参考这个网友的方法和流程：

http://www.zyh1690.org/used-in-the-mfc-opencascade-example/

2.1 点击VS的文件 - 新建 - 项目，输入工程名字“myBottle111”，如下图

2.2 点确定后，在弹出的界面，点下一步，选择单文档，选择MFC标准，然后点完成即可

2.3 设置工程为x64, 因为使用的lib和dll都是64位的，点击VS的项目 - 属性，在弹出界面的右上角点击 “配置管理器”，在弹出的界面，按照下图，点击“新建”

2.4 在弹出界面，点击确定

设置成功后，变成下图界面

2.5配置包含路径，点击VS的项目 - 属性，点右边的配置属性下一级的 “VC++目录”，分别编辑 “包含目录”、“库目录”、“源目录”

依次各增加一个路径

“C:\OpenCASCADE7.1.0-vc10-64\opencascade-7.1.0\inc”

“C:\OpenCASCADE7.1.0-vc10-64\opencascade-7.1.0\win64\vc10\lib”

“C:\OpenCASCADE7.1.0-vc10-64\opencascade-7.1.0\src”

三、编辑工程

3.1 在工程，解决方案视图，找到“stdafx.h” ，打开后，添加以下头文件

3.2 在解决方案视图，给解决方案新建一个文件夹，右键“myBottle111”，文件夹命名为“lib”

3.3 添加cascade库文件，右键“lib”文件夹 —— 添加 —— 现有项

在弹出界面中，定位到“C:\OpenCASCADE7.1.0-vc10-64\opencascade-7.1.0\win64\vc10\lib”目录，然后选中全部的lib，点击添加。这里不知道后续会用到哪些lib，所以讲全部的lib都添加进工程。

3.4 接下来，点击VS的调试 - 启动调试，则会弹出确实dll文件，这是第三方库的依赖，需要将这些dll文件拷贝到工程输出的文件，本次使用的是debug文件夹，所以要拷贝到debug文件夹目录下。四个dll文件可在这个链接下载

https://download.csdn.net/download/zxc2008/11195744

本教程的目录是“..\myBottle111\x64\Debug”

拷贝过去后就能成功了

以上就已经完成了对open cascade环境的搭建支持。

后续操作就跟网友的完全一致了，http://www.zyh1690.org/used-in-the-mfc-opencascade-example/

四、画一个瓶子

4.1 在APP类头文件中添加标准宏定义和图形设备头文件

#include <Standard_Macro.hxx>
#include <Graphic3d_GraphicDriver.hxx>

4.2 在APP类添加以下成员变量和方法（不理解的，需要重新学习C++知识，ps：我就是这么过来的）：

   //头文件注意，别把下面这几行代码放在DECLARE_MESSAGE_MAP()后面了！
   Handle_Graphic3d_GraphicDriver myGraphicDriver;
   Handle_Graphic3d_GraphicDriver GetGraphicDriver()const {return myGraphicDriver;} ;

4.3 在APP类的构造函数中完成对设备环境生成和初始化：

try
{
Handle(Aspect_DisplayConnection) aDisplayConnection;
myGraphicDriver = new OpenGl_GraphicDriver (aDisplayConnection);
}
catch(Standard_Failure)
{
// AfxMessageBox ("Fatal error during graphic initialization", MB_ICONSTOP);
ExitProcess (1);
}

此时编译会提示如下错误：

原因是因为OpenCascade对new操作符进行了重载，与VS中的定义存在冲突，屏蔽CPP文件前面的以下代码就可以解决了。

#ifdef _DEBUG

/*#define new DEBUG_NEW*/

#endif

后面OpenCascade使用new操作符的地方，都需同样的方法解决。更多请阅读：

五、接下来：在Document类中添加OpenCasCade间接设备环境和图形接口

5.1在Doc类的头文件中添加OpenCasCade成员变量和方法：

//几个方法的声明和定义分开写，在调用时会有LNK2019错误，原因不明（我才特么没有写错字母），知道的亲还请留言告知，(∩_∩)
public:
   Handle(V3d_Viewer) myViewer;
   Handle(AIS_InteractiveContext) myAISContext;
   Handle(AIS_InteractiveContext)& GetAISContext(){ return myAISContext;}
   Handle(V3d_Viewer) GetViewer(){   return myViewer;}
   Handle(AIS_InteractiveContext)& GetInteractiveContext(){ return myAISContext;}

5.2 接着在Doc类的构造函数中完成对OpenCasCade变量初始化设置：

// TODO: 在此添加一次性构造代码
Handle(Graphic3d_GraphicDriver) aGraphicDriver = ((CmyBottle111App*)AfxGetApp())->GetGraphicDriver();

TCollection_ExtendedString a3DName("Visu3D");
myViewer = new V3d_Viewer(aGraphicDriver,a3DName.ToExtString());

   myViewer->SetDefaultLights();
   myViewer->SetLightOn();
   //myViewer->SetDefaultBackgroundColor(Quantity_NOC_BLUE1);//改变背景颜色

   myAISContext =new AIS_InteractiveContext(myViewer); //创建一个交互文档
   myAISContext->DefaultDrawer()->UIsoAspect()->SetNumber(11);
   myAISContext->DefaultDrawer()->VIsoAspect()->SetNumber(11);

   //这里设置实体的显示模式
   myAISContext->SetDisplayMode(AIS_Shaded,Standard_False);

六、View类中的OpenCasCade变量设置以及图形显示设置

6.1 添加变量：

private:
Handle_V3d_View myView;
Standard_Boolean myHlrModeIsOn;

6.2 添加OnInitialUpdate() ，在类视图中，右键 CView，选择类向导，在点弹框的“虚函数”，选中OnInitialUpdate() 后，双击，然后点弹框的应用 ——确定。

6.3 重写 OnInitialUpdate() 函数，添加如下代码：

   CView::OnInitialUpdate();
// TODO: 在此添加专用代码和/或调用基类
   myView =((CmyBottle111Doc*)GetDocument())->GetViewer()->CreateView();
   myHlrModeIsOn = Standard_False;
   myView -> SetComputedMode(myHlrModeIsOn);
   Handle(Graphic3d_GraphicDriver) aGraphicDriver = ((CmyBottle111App*)AfxGetApp())->GetGraphicDriver();
   Handle(WNT_Window) aWNTWindow = new WNT_Window(GetSafeHwnd());
   myView->SetWindow(aWNTWindow);

if (!aWNTWindow->IsMapped()) aWNTWindow->Map();
aWNTWindow->SetBackground(Quantity_NOC_SLATEBLUE2);

6.4 在OnDraw函数中添加OpenCasCade的重绘代码：

void CneedAVView::OnDraw(CDC* /*pDC*/)
{
   CneedAVDoc* pDoc = GetDocument();
   ASSERT_VALID(pDoc);
   if (!pDoc)
       return;

myView->Redraw();
// TODO: 在此处为本机数据添加绘制代码
}

至此，运行程序，你便可以看到 OpenCasCade 灰灰的窗口了

七、开始画瓶子

后面可以使用OpenCasCade工作。直接用官方给的画瓶子的函数代码即可（给View类添加MakeBottle方法，很多人因为这个出错，请大家仔细看教程），MakeBottle函数代码如下（所需的头文件，已全部在stdafx.h，类方法的构造都在lib文件中）

TopoDS_Shape CmyBottle111View::MakeBottle(const Standard_Real myWidth, const Standard_Real myHeight,const Standard_Real myThickness)
{
   // Profile : Define Support Points
   gp_Pnt aPnt1(-myWidth / 2., 0, 0);

   TopoDS_Edge anEdge1 = BRepBuilderAPI_MakeEdge(aSegment1);

   mkWire.Add(aWire);
   mkWire.Add(aMirroredWire);
   TopoDS_Wire myWireProfile = mkWire.Wire();

   // Body : Prism the Profile
   TopoDS_Face myFaceProfile = BRepBuilderAPI_MakeFace(myWireProfile);

   TopoDS_Shape myBody = BRepPrimAPI_MakePrism(myFaceProfile, aPrismVec);

   // Body : Apply Fillets
   BRepFilletAPI_MakeFillet mkFillet(myBody);
   TopExp_Explorer anEdgeExplorer(myBody, TopAbs_EDGE);
   while(anEdgeExplorer.More()){
       TopoDS_Edge anEdge = TopoDS::Edge(anEdgeExplorer.Current());
       //Add edge to fillet algorithm
       mkFillet.Add(myThickness / 12., anEdge);
       anEdgeExplorer.Next();
   }

myBody = mkFillet.Shape();

   // Body : Add the Neck
   gp_Pnt neckLocation(0, 0, myHeight);
   gp_Dir neckAxis = gp::DZ();
   gp_Ax2 neckAx2(neckLocation, neckAxis);

Standard_Real myNeckRadius = myThickness / 4.;
Standard_Real myNeckHeight = myHeight / 10.;

BRepPrimAPI_MakeCylinder MKCylinder(neckAx2, myNeckRadius, myNeckHeight);
TopoDS_Shape myNeck = MKCylinder.Shape();

myBody = BRepAlgoAPI_Fuse(myBody, myNeck);

   // Body : Create a Hollowed Solid
   TopoDS_Face faceToRemove;
   Standard_Real zMax = -1;

   for(TopExp_Explorer aFaceExplorer(myBody, TopAbs_FACE); aFaceExplorer.More(); aFaceExplorer.Next()){
       TopoDS_Face aFace = TopoDS::Face(aFaceExplorer.Current());
       // Check if <aFace> is the top face of the bottle抯 neck
       Handle(Geom_Surface) aSurface = BRep_Tool::Surface(aFace);
       if(aSurface->DynamicType() == STANDARD_TYPE(Geom_Plane)){

           gp_Pnt aPnt = aPlane->Location();
           Standard_Real aZ = aPnt.Z();
           if(aZ > zMax){
               zMax = aZ;
