MFC集成OpenCascade

1、OpenCasCad环境变量设置

在我的电脑的环境变量中增加OpenCasCade的相关配置信息

头文件：CSF_OCCTIncludePath：D:\Program Files\OpenCASCADE-7.3.0-vc14-64\opencascade-7.3.0\inc

Lib文件：CSF_OCCTLibPath：D:\Program Files\OpenCASCADE-7.3.0-vc14-64\opencascade-7.3.0\win64\vc14\lib

bin文件： PATH路径中增加occt的相关路径，特别注意标红的路径

 

 

2、新建MFC应用

打开VS2019->新建项目->MFC应用（没有的话使用左下VS安装程序下载MFC板块）->确定

创建完成之后，一定要先将上面的x86改成x64 ，再进行配置

 

3、配置VS项目

右键项目->属性->VC++目录中设置包含目录，及库目录

 

 

 在连接器中增加所依赖的lib文件

 

 技巧：

在openCasCade的lib路径中，输入cmd，在命令行中输入dir /b >lib.txt，将会把该目录中的所有lib文件名重定向到lib.txt中，然后讲所有的lib列表添加到依赖项中

 

 

4、修改pch.h中，在pch.h中将常用的opencascad里的头文件

#include <Interface_Static.hxx>  
#include <OpenGl_GraphicDriver.hxx>

5、修改项目中的各个类

xxxApp.h

    Handle(Graphic3d_GraphicDriver) m_GraphicDriver;
    Handle(Graphic3d_GraphicDriver) GetGraphicDriver() { return m_GraphicDriver; }

添加包含的头文件

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

 

在相应类的构造函数中添加

    try
    {
        Handle(Aspect_DisplayConnection) aDisplayConnection;
        m_GraphicDriver = new OpenGl_GraphicDriver(aDisplayConnection);
    }
    catch(Standard_Failure)
    {
        AfxMessageBox(_T("Error ocured in Initializing the Opencascad graphic variable."));
    }

 

 

注意如果new报错（因为该文件开头对new做了重定义），有下面两种方法，一是把整个#define Debug注释掉

另一种是仅把define new DEBUG_NEW注释掉

 

 

 

 

xxxdoc类的修改

xxxdoc.h

    Handle(AIS_InteractiveContext) m_AISContext;
    Handle(V3d_Viewer) m_Viewer;

 

 

 xxxdoc.cpp 在构造函数中添加

    Handle(Graphic3d_GraphicDriver) theGraphicDriver = ((COCCDemoApp*)AfxGetApp())->GetGraphicDriver();
    m_Viewer = new V3d_Viewer(theGraphicDriver);
    m_Viewer->SetDefaultLights();
    m_Viewer->SetLightOn();

    m_AISContext = new AIS_InteractiveContext(m_Viewer);
    m_AISContext->SetDisplayMode(AIS_Shaded, true);
    m_AISContext->SetAutomaticHilight(Standard_False);

 

 

 

xxxview类的修改

xxxview.h

Handle(V3d_View) m_View;
void FitAll();

virtual void OnInitialUpdate();

 

 

xxxview.cpp中的添加

void COCCDemoView::FitAll()
{
    // TODO: 在此处添加实现代码.
    if (!m_View.IsNull())
    {
        m_View->FitAll();
        m_View->ZFitAll();
    }
}

void COCCDemoView::OnInitialUpdate()
{
    CView::OnInitialUpdate();

    // TODO: 在此添加专用代码和/或调用基类
    m_View = GetDocument()->GetViewer()->CreateView();
    m_View->SetShadingModel(V3d_GOURAUD);

    Handle(Graphic3d_GraphicDriver) theGraphicDriver = ((COCCDemoApp*)AfxGetApp())->GetGraphicDriver();

    Aspect_Handle aWindowHandle = (Aspect_Handle)GetSafeHwnd();
    Handle(WNT_Window) aWntWindow = new WNT_Window(GetSafeHwnd());
    m_View->SetWindow(aWntWindow);
    if (!aWntWindow->IsMapped())
    {
        aWntWindow->Map();
    }

    Standard_Integer w = 100;
    Standard_Integer h = 100;
    aWntWindow->Size(w, h);
    ::PostMessage(GetSafeHwnd(), WM_SIZE, SIZE_RESTORED, w + h * 65536);
    m_View->FitAll();

    m_View->ZBufferTriedronSetup(Quantity_NOC_RED, Quantity_NOC_GREEN, Quantity_NOC_BLUE1, 0.8, 0.05, 12);
    m_View->TriedronDisplay(Aspect_TOTP_LEFT_LOWER, Quantity_NOC_WHITE, 0.2, V3d_ZBUFFER);
}

 

 在绘制函数中OnDraw中添加

    if (m_View)
    {
        m_View->MustBeResized();
        m_View->Update();
    }
